Delta Bathroom Faucet Leaks: A Simple Fix in Less Than 5 Minutes

Delta Bathroom Faucet Leaks-A Simple Fix in Less Than 5 Minutes

How can I stop the annoying drip coming from my bathroom faucet, it’s driving me crazy?

Have you ever asked yourself this question? I have plenty of times.

A bathroom faucet leak can be one of the most frustrating things about being a homeowner.

But don’t fear this common problem. You can do this fix yourself and save your money for the movies instead.

What’s the worst that could happen? You could forget to turn off the water at the shutoff valve and have a gusher.

Okay, I admit I’ve done this πŸ™‚

This post deals with repairing a Delta bath sink two-handle centerset faucet. If that isn’t a mouthful I really don’t know what is. The faucet in question is in the picture.

This small quick project requires the following supplies:

  • Delta Universal Seats & Springs Repair Kit ($4.47)(Part RP4993)
  • Delta Stem Unit Assembly ($13.26) (Part RP25513)
  • Allen wrench ($10.97)
  • Channel Locks ($13.96)
  • Needle Nose Pliers ($5.00)

If you have all of these tools or can borrow them the cost for the Delta replacement parts is under $20.00.

I’m sharing this tutorial because I’ve had to do this repair many times and discovered a few tips that will help you make it quick and painless. Plus, there’s a video for your viewing enjoyment. Don’t bother grabbing popcorn, it’s only 3 minutes long (tight budget, haha).

So let’s do it!

Determine Where the Delta Bathroom Faucet is Leaking

The first step is to identify the type of faucet you have. In this case I’m repairing a bathroom sink two-handle centerset faucet.

Then you’ll need to determine the area of the faucet that is leaking.

Is the leak coming from under the Delta bathroom faucet handle or is the leak coming from the aerator?

I knew the leak was coming from the aerator because I saw it first thing in the morning when I shuffled into the bathroom to begin my day. The pop-up stopper was always wet which indicated a persistent drip.

Turn the hot water shutoff valve under the sink to the off position (completely to the right). Check to see if the leak is still there. If the leak is gone you know the hot water side of the faucet is the culprit.

If the drip persists then you know the cold water side of the faucet is to blame.

You can also follow this flow chart to figure out HOW to fix the Delta bathroom faucet leak.

(A special thanks to Powell Svendsen for pointing out an error on the first version of my flow chart :))


Using a Delta Bathroom Faucet Repair Kit

Before you do anything make sure the water is turned off to faucet. You’ll only have to shut off the water to the corresponding handle that was causing the drip.

As promised, here’s the video that walks you through this entire fix but you can also view the pictures below if you prefer that instead.


[tubepress video = “WcEh7gMm-7A”]


To access the Delta faucet cartridge and seats & springs you’ll have to remove the faucet handle & body.

Unscrew the delta faucet handle by hand and use an allen wrench to loosen the set screw that holds the handle body in place. Remove the faucet handle body and set it aside.

Unscrew the stem unit nut with channel locks.

Take a picture of the stem unit before you remove it with the channel locks. Believe it or not there is a proper way to reinstall it and a picture comes in handy.

Remove the old delta faucet cartridge with channel locks or needle nose pliers.

If you need to replace the little rubber seat and metal spring you can use needle nose pliers to do so. I tried using my wife’s tweezers but they didn’t work (don’t tell her, she wouldn’t be happy).


Delta Bathroom Faucet Leaks-Extract the old seat and spring


I always put the new seat and spring down into the faucet together as one unit. Just make sure they are oriented like in the picture below with the wider side of the spring facing down into the faucet.

Firmly press the seat & spring into the faucet. If you need to replace the cartridge because you had a drip coming from the aerator go ahead and do that now following the tips in my video. As an FYI, one of my readers (Powell Svendsen) was able to clean the O-rings on the cartridge and eliminate a leak coming from the aerator. So you could give this a try before buying a new cartridge unit.

Thanks Powell for sharing your great tip!!

Screw the stem unit lock nut onto the faucet base and put the Delta faucet handle back in place.

You’re done!!!

    Are we living in some parallel universe or something? Our bathtub faucet was leaking this weekend, I went ahead and replaced the stems and all. But, I also have a sink faucet that dribbles when on full force. I’m pretty sure it is clogged in the faucet and the aerator just crumbled in my hands. So, I’m off to get a new faucet…and it will be a Delta for sure!

    • Jeff Patterson November 21, 2012, 1:22 PM

      Parallel universe indeed, haha.

      You can’t go wrong with Delta, Moen, or American Standard. There are so many awesome styles to choose from. Please let us all know which faucet you choose over on prettyhandygirl.com πŸ™‚

  • jsid November 22, 2012, 11:23 AM

    Thank you for this valuable info.

    My bathtub shower has a single knob and the drip is from the spout. Delta model #1600, cartridge # RP1991, purchased & installed in December 24,2007.

    Delta company wants me to send them the UPC number on the box or a receipt from the store. In 2005, we had hurricane Katrina,then later years ,Gustavo and recently Issac.It is very difficult to keep all the receipts of the last 4 years and to find the box.So the company refused to give any replacement part, even under 5 year warranty.They quoted my the price for the cartridge at $23.55. I found the same cartridge on http://www.ebay.com for $13.00(free shipping). I am hoping to replace the cartridge to stop the leak…..thank you jeff….:)

    • Jeff Patterson November 25, 2012, 8:33 PM

      You’ve been through a lot!!!

      I can’t blame you for being frustrated. Usually the big companies like Delta are pretty good about warranties.

      The cartridges are pricey and buying name brand is sometimes worth it just for the peace of mind. Let me know how you make out and if your drip gets fixed.

      I am super happy I was able to help πŸ™‚

  • Ira Morse November 22, 2012, 8:01 PM

    Wow, what nice tips you have here…the good thing about this Delta Bathroom Faucet is that it has a repair kit, so it is easy to fix it.

    • Jeff Patterson November 25, 2012, 8:17 PM

      You brought up a great point Ira, buy faucets that you know have repair kits.

      Here in the states Moen, Delta, American Standard, and Kohler are the brands that have easily accessible repair parts. Sometimes the faucets are a bit pricier but it’s worth it because they have warranties and last longer than cheaper varieties.

      I’ve bought cost effective (aka low quality) faucets in the past and have always had problems with them within a few years. Lesson learned πŸ™‚

  • Leida December 11, 2012, 9:21 PM

    I have one of those faucets, and this tutorial sure helps. Thanks so much for this well prepared video.

    • Jeff Patterson December 11, 2012, 9:23 PM

      Glad it was helpful Leida. Always feel free to ask any question, I’d be more than happy to assist πŸ™‚

  • Stephanie January 29, 2013, 12:27 AM

    This was an easy fix until i tried to put the cartridge back in. I cannot do this to save my life. The seal and spring are as pictured, but the cartridge wont fit back down – I tried aligning the white tabs with the slots on the cartridge holder; tried pushing the cartridge down with a 12 pound weight, but it won’t go far enough in to allow the bonnet nut to engage. Any tips before I have to call a plumber to clean up this “easy fix”?

    • Jeff Patterson January 29, 2013, 5:44 AM

      Hmmm, was your cartridge exactly the same as the one in the post Stephanie?

      Do you mind send me some pictures at jeff@homerepairtutor.com and that way I can see what the problem might me?

  • Karen Mortensen March 17, 2013, 4:35 PM

    I saw your wonderful video but my handle just is not willing to come off after I removed the set screw.

    I have wd40ed and pryed and pryed it just won’t come off. Is there a trick?

    On the video you just pulled it right up and off. Mine will not do that so I can’t get to the innerds to pull out the stuff to be replaced. Please help.

    • Jeff Patterson March 19, 2013, 5:34 AM

      Karen, would you mind sending me a picture of your handle? Send it to jeff@homerepairtutor.com.

      Sorry to hear you’re having so much trouble with this fix. We’ll figure it out together πŸ™‚

  • Armando Sardanopoli May 7, 2013, 6:05 PM

    have a delta bath sink faucet with a swivel neck. The leak is comin from the base of the swivel neck. Can this be fixed or is it the nature of this design?

  • Carl May 27, 2013, 6:01 PM

    Thanks Jeff. Your video truly made this a 5 minute repair!!

    • Jeff Patterson May 29, 2013, 4:29 PM

      Awesome Carl. You just encouraged me to make more videos πŸ™‚

  • Marty Rhoden June 20, 2013, 6:22 PM

    Hi Jeff,
    I replaced a stem, seat and springs on my dripping Peerless bathroom faucet after watching a tutorial. I was patting myself on the back for a job well done. It didn’t drip for a few weeks and then oh my gosh a stream was coming out… for several hours while I was out in the yard. I just set the spring and seat on the little hole and placed the stem back on. The video said nothing about pressing down on the seat and spring. So how exactly do you press it down (how firmly)….with the needle nose pliers? Would that have been why all of a sudden it started streaming out? Also I used a universal stem …for several different faucets….should I stick with a Peerless stem? The universal one doesn’t have metal on the bottom like the original Peerless one. Okay one more question….In setting the stem I couldn’t push it all the way down to slide in the notches….how do you do that at the same time your screwing the nut back on? Thanks

    • Jeff Patterson June 21, 2013, 5:55 AM

      Marty, thanks for your questions. Always use the manufacturer’s step instead of a universal variety. I’ve made the same mistake and it just stinks when something wrong happens like in your case. You mentioned that the stem couldn’t be pushed completely down to engage the notches. So this is one clue that the stem wasn’t fitting correctly. If you have the old stem take it to the hardware store or a plumbing store and get the name brand replacement part. The replacement stem should completely sit down into the faucet in the notches then you can tighten the nut.

      You can push the seat and spring down into the faucet until they don’t go any further. Sorry I didn’t explain this in the video. Use your index finger to accomplish this job instead of something like the pliers so that the rubber seat doesn’t get ruined or torn. Hope this helps πŸ™‚

  • Jey July 22, 2013, 9:07 PM

    Hi Jeff,

    Thank you for the great info. It was a big help!! I may have the answer to one of your readers question. Hard water (calcium) hardens the assembly and it becomes almost impossible to unscrew a part. I sprayed Lime Away on the part (make the part more accessible to Lime Away by opening anything that you possibly can) then cover with a towel, spray some more Lime Away, and finally cover with an air tight plastic bag. Leave overnight or even more and it should come off. Hope this helps!!

    • Jeff Patterson July 24, 2013, 7:02 AM

      Hi Jey,

      Lime Away-cool!!! For some reason my thick head never thought of using it. Thanks so much for the great DIY Insider Tip!!



  • Chloe Benson August 13, 2013, 1:55 PM

    Thank you for the great article! I have a Peerless bathroom faucet currently installed…I tried fixing it but I was unable to do so! Instead I just had to buy a new one, thank goodness for PlumbersStock, the online retailer I purchased it from, because I could actually afford it! XO

    • Jeff Patterson August 13, 2013, 2:39 PM

      Hi Chloe,

      Sorry to hear that you needed to replace your faucet. Bummer πŸ™

      Thanks for bringing Plumbers Stock to our attention. I’ll have to check it out the next time we need some supplies-which seems like all the time!!



  • Tom October 28, 2013, 2:42 PM

    Thanks for the article. I have a delta bathroom faucet that was leaking. I followed your directions. I have everything in place, but two issues: 1.) it appears that when I put the handle on to the stem, it doesn’t go all the way down to the base. It is really loose. Not sure if I don’t have the spring and washer all the way down? 2.) the set screw does not seem to want to “catch” onto the stem. Any tips for making this easier? Thanks, Tom

    • Jeff Patterson October 28, 2013, 9:15 PM

      Hi Tom, thanks for your questions. Make sure the cartridge is in the correct way and the whole way down. There is likely a slot on the faucet base that the cartridge should fit into. One way to see if the cartridge is in the right way is to remove the other handle and compare the setup. I’d do it if you lived close to the Burgh, Tom πŸ™‚

      This could also explain why the set screw isn’t catching properly. Let me know if this helps Tom.


      • Jennifer February 11, 2016, 7:48 PM

        I have the same problem. I am sure that the pieces are all correctly placed, but the handle will not go all the way on. When I look inside the hollow handle, there seems to be some residue – not enough for me to think it would stop the handle going on, though. Hard water residue? I live in OR, in a fairly new subdivision. Anything you can recommend for me to try?

        • Jeff Patterson February 13, 2016, 7:32 AM

          It could be that your cartridge isn’t installed correctly Jennifer, hard to say without seeing it. The stem has to be lined up correctly as well for some handles to fit back onto the cartridge.

  • Helen November 17, 2013, 8:06 PM

    I replaced the spring and seat, since I had an infrequent drip from the faucet. I’ve replaced these several times over the years and all has been well.

    This time, my drippy faucet is fixed, but I have a pretty steady leak underneath the sink where the hot water line connects to the sink basin. Help! I’m afraid to tighten anything under the sink. This is foreign territory for me.

    • Jeff Patterson November 17, 2013, 8:36 PM

      Hi Helen,

      Don’t be afraid, you can fix this drip. It sounds like the connection between the supply line and the faucet needs to be tightened by 1/4 to 1/2 turn.

      Chances are you’ll need a basin wrench to tighten the nut on the supply line. This tool costs $15 to $20 and helps you reach the nut without removing the sink.

      You can buy basin wrenched at any hardware store.

      If you are looking up at the connection from under the sink, turn the nut clockwise to tighten it.

      If you cannot fit under the sink (like me) you can still tighten the nut with the basin wrench. But turn it counterclockwise from this perspective in order to tighten the nut.

      I hope this helps and let me know if you’ve got more questions.

      • Helen November 17, 2013, 9:29 PM


        There’s a thin white plastic fitting between the brass supply pipe and the sink base. It’s kind of hard to describe. I’m worried I’ll break that with a wrench.

        • Jeff Patterson November 17, 2013, 10:06 PM

          That nut holds the faucet tight to the sink. The nut you’d need to tighten is on the supply.

      • Helen November 17, 2013, 9:31 PM

        I wonder if I’ve put something back in wrong or perhaps I need a new stem. Would that cause a leak under the sink? I also see some water appearing under the faucet handle base when I turn on the water. That was not happening before.

        • Jeff Patterson November 17, 2013, 9:45 PM

          Hi Helen,

          If you didn’t tighten the nut enough that holds the stem in place then water will leak from under the handle.

          Here’s my prescription:

          1. Tighten the nut by 1/4 to 1/2 turn clockwise that holds the stem in place

          2. If you still see water dripping from under the handle then take the stem to the store and get a replacement.

          I hope this makes sense πŸ™‚

          • Helen November 17, 2013, 10:35 PM


            Yes it does. I’ll try tightening the nut first. I don’t think I’ve ever replaced this stem–only the seat and spring. Perhaps it’s time for a replacement.

            I emailed you a picture of the hard-to-describe new leak from underneath.

            I love this page, by the way. Makes me feel “almost” handy.


          • Jeff Patterson November 19, 2013, 5:22 AM


            Let me know if tightening the nut helps or if the cartridge needed to be replaced. Either way, I hope this helps you πŸ™‚

  • PeggySue November 18, 2013, 11:20 PM

    Hi, I watched your video but my handle will not come off. The handle is off and I removed the set screw but the handle body will not budge! I have 2 sinks with leaky handles, neither one will come off!

    I have used WD 40 and tried prying with a screwdriver but they won’t come off. Do you have any other suggestions?

    I have cold water on one sink and hot on the other, not very convenient.

    • Jeff Patterson November 19, 2013, 5:29 AM

      Hi PeggySue,

      Do you mind sending me a few pictures of your handles? That will help me figure out this conundrum πŸ™‚

      Send them to jeff@homerepairtutor.com

      • mike February 15, 2015, 11:30 AM


        Did you ever figure this out? I am having the same issues… cannot get the handle off…


  • Todd January 8, 2014, 12:22 AM

    Hi Jeff–I’m REALLY frustrated with my Delta single handle tub faucet (Monitot 13 Series). A few days ago, water started dripping steadily from the bathtub spout even with the faucet handle all the way in the off position. I took the faucet apart and replaced the old cartridge with a new one (Part# RP19804). I reassembled the faucet, but the steady drip from the end of the spout still persists even with the hanbdle in the off position. The spout is a generic model in which the shower diverter is activated by pulling down on the round collar at the end of the spout where the water comes out. What could cause this drip? Did I just waste $45 for a new cartridge?

    • Jeff Patterson January 12, 2014, 3:17 PM

      Thanks Todd for your question.

      So you still have a drip coming from the spout. Okay, does your cartridge slot have seats and springs? That’s one thing that you might need to replace if you have them. You’ll have to pull the cartridge out to reach them but if they’re bad you’ll still have a drip coming from the shower head or tub spout.

      Please let me know if you have seats and springs because I’d like to help you figure out this problem.

  • Duncan P February 6, 2014, 2:22 AM

    Thanks for the video, and the parts list. I wanted to mention that the replacement cartridge comes with an extra plastic ‘tooth’. I did not understand it’s use until I realized that in order to get the two faucets to rotate in the correct opposite directions, one had to add a plastic tooth to one of the cartridges (look carefully at the leaking one to see where you need to add that tooth in). In my case it was to the cold water side.

    • Jeff Patterson February 7, 2014, 3:05 PM

      Yah, that’s right. I forgot about the extra insert Duncan. Thanks for pointing that out. This is super important since often times it’s easy to forget to replace the insert in the right position. Or it might just get lost during the repair process.

      I lose stuff all the time. Oh, and another tip I just thought about. Make sure to put the pop-up stopper in the down position so that nothing gets lost down the drain!!!

      Yep, this has happened to me a few times.

  • Abbey February 18, 2014, 12:23 AM

    Jeff-I replaced the seat and the spring and it seemed that all went well till I put everything back together and turned the water on now the water runs if the faucet is turned on or off. What did I do wrong?

    • Jeff Patterson February 18, 2014, 5:29 AM

      Hi Abbey, thanks for your question. The good news is that this is easy to fix. You likely inserted the cartridge the wrong way.

      When this is done the water will run continually. Simply turn the cartridge 180 degrees and your faucet should work the right way.

      Hope this helps. It’s a bit alarming when you see the faucet behave the way you did. But you can fix it πŸ™‚

  • Susan March 22, 2014, 12:31 PM

    When we moved into our house, we discovered that the master shower handle temperature control is weird. Off is at four oclock position. As you turn the handle counter clockwise, the water temp goes from cold to warm at one oclock, hottest at twelve oclock and cools off at eleven. Turning the handle all the way counter clockwise to the stop gives cold water! What do you suggest?

    • Jeff Patterson March 29, 2014, 9:00 AM

      I had the exact same situation Susan. It’s most likely a cartridge being inserted incorrectly.

      What kind of shower handle do you have (e.g. Moen, Delta, Kohler)?

  • Chris Schelling April 16, 2014, 8:01 PM

    I have the exact same faucet, and none of my allen wrenches work – none are even close. The size is somewhere in between a 2.5mm and 2mm allen wrench and between a 3/32 and 5/64. The bigger ones don’t go in and the smaller ones just slip. What gives? And what am I supposed to do?

    • Jeff Patterson April 18, 2014, 5:34 PM

      Chris, I’ve run into the same issue. And the ultimate problem was a stripped set screw, bummer! So I decided to call Delta and ask them for a new handle. They sent two replacements in the mail for free, which was awesome since the handles were expensive.

      I had to drill out the set screw with a small bit. This ruined the existing screw but it was already toast. The drill put a small hole in the cartridge stem but that wasn’t a big deal and the new handles slipped on with no problem.

      Sorry I don’t have a better solution but figured I’d share my experience πŸ™‚

  • John May 18, 2014, 7:23 PM

    I just fixed my bathroom faucet with your advice. It was quick and simple. thank you.

    • Jeff Patterson May 26, 2014, 7:34 AM

      Sweet!!! Thanks John for letting me know.

      If you have any questions on other stuff just let me know.

  • Joe July 26, 2014, 10:50 PM

    Thanks for the video. I learn better by seeing than reading.

    This would have been a 5 minute fix but… How did you get the spring to stay in the seat ? Mine just kept falling out. Finally just put the spring in and attempted to get the seat on top of it. I guess time will tell if I did it right.

    • Jeff Patterson July 27, 2014, 9:05 AM

      Sounds like you did it right Joe. You’ll know right away if you did it wrong. The cartridge won’t sit properly.

      One thing I like to do is put the spring down in the hole then add the seat. It’s not easy if you’ve got chubby fingers like me but works.

      You could also put the spring & seat together on an Allen wrench and fish the wrench end down into the hole. This is a good option as well.

  • Le August 12, 2014, 12:12 AM

    The handles on my Roman Tub faucet do not line up. I was attempting to fix a constant drip. I changed the cartridges and began tightening the bonnet nut and the entire valve twisted. Now the handles do not line up when I align the cartridge with the notches. What do I need to do to fix this? Water is now leaking from under the base around the tub where the handle is attached.

    • Jeff Patterson August 12, 2014, 4:56 AM

      Hmmm, send me a picture Le of your setup. It sounds like there’s another nut that needs to be tightened. Hence the valve movement.

  • Mack September 28, 2014, 11:31 AM

    I replaced the seats, springs, and cartridges in my bathroom delta sink which had a leak. Now no water will flow out of the faucet. I have made sure that the water is on under the sink, and have tried multiple aerator configurations with no success. What am I missing?

    • Jeff Patterson September 29, 2014, 5:36 AM

      Hey Mack, this sounds like you reversed the cartridge in the faucet. If you did you won’t see the water run at all. Take the cartridge up out of the faucet and spin it 180 degrees. I bet you’ll see the faucet work properly after that πŸ™‚

  • missy sturgeon October 9, 2014, 2:22 PM

    Jeff-I had the exact same issue as Abbey did on 2/14/14-reassembled everything and when I turned the water supply on the cold side was running without turning the handle. I tried flipping the cartridge 180 degrees, but when I put the 1/4 turn stop in that way, the handle does not fit back down over the cylinder. There are only 2 different ways that cylinder can go in, right? When I did get the handle on the second time, the water was still running and the handle had to be turned backwards, instead of forward to turn on. Help!

  • Missy October 10, 2014, 10:18 AM

    Jeff — I had the same issue as Abbey did (2/18/14 comment) where I installed everything and turned the main water source back on and the water began coming out of the cold side of the faucet without even turning the handle–continuous flow. I tried flipping the cylinder/stem the 180 degrees, but then my handle will not fit back down onto the cylinder. It seems there are only 2 ways the stem can fit back down into the fixture, either way I can’t get it to work–one way the handle won’t fit back down over it or the other way the turning of the handle is backwards. It does have a 1/4 turn stop that I’ve tried putting in both ways and still no luck. I tried to replicate the identical faucet assembly on the other side and everything looks right, but obviously I’m doing something wrong. Help!

    • Jeff Patterson October 14, 2014, 5:40 PM

      Hey Missy, it sounds like your stem got turned around. You’ll have to compare the stem position on the other cartridge and see it’s orientation. Then turn the stem on the cartridge you removed to match that orientation.

      If you’d like you can take a picture of both stems and I’d be happy to look at them.

    You rock! Thank you so much for the detailed instructions. I am so excited I fixed this myself.

    • Jeff Patterson October 19, 2014, 11:33 AM

      That’s awesome Nalani!!!!

      So glad to hear your fix went smoothly πŸ˜€

  • Alan December 19, 2014, 7:10 PM

    I’m trying to service a one-lever Delta kitchen faucet (the old generic style) and the spout just won’t come off. I’m pulling hard enough to break something and it just won’t come off. Do you have any ideas that I could try? (No I am not just grabbing the spout and pulling at an angle.)
    Thank you kindly.

    • Jeff Patterson December 19, 2014, 9:22 PM

      Thanks Alan for your question. Does the faucet have a set screw?

  • Tom January 18, 2015, 2:36 PM

    I have a 2-handle tub faucet (Delta H64). The handles move 180 degrees from closed to full open. The faucet was dripping unless the cold handle was SLIGHTLY moved off the fully-closed position. Then it stops dripping. I replaced the valve body (Delta RP25513) and the rubber seat and spring. However, the problem persists. The orientation of the valve body is set by the 2 locating tabs so I wonder if the locating tabs and the ports in the bottom of the valve could somehow be misaligned? If so, what’s the fix. Or is it something else? Thanks!

    jeff: I have a delta bathroom faucet that has been leaking. I replaced the stems and the seals and sprigs bt te

  • Stan Sleva January 18, 2015, 3:20 PM

    Jeff: After replacing my delta stems and seats and springs my hot water starts leaking after one or two days. I replaced the hot water seals and springs three times but it once again leaks after a day or two. I have replaced the seals and springs before but this has never happened before. Any advice before I replaced the Delta faucet. It is only about three years old. Thanks so much.

    • Dane October 30, 2015, 12:22 AM

      I’m facing the same issue. Delta says you have to flush the lines to ensure there isn’t sediment or debris in the faucet somewhere that’s causing issues with the stems. Haven’t tried yet but I’m really hoping it works. May not be buying Delta again if it doesn’t.

  • DavidKeller January 18, 2015, 4:31 PM

    Jeff, I have a delta shower faucet, Monitor 1400 series installed in 1998. It started dripping recently. Delta sent a free replacement cartridge and I installed it. The original cartridge was difficult to remove, probably due to calcium buildup. I have hard water where I live. The replacement cartridge was also difficult to install. I was finally able to get the plastic tabs on the cartridge to align with the notches on the brass body. The faucet still drips. I contacted DELTA and they sent a 2nd cartridge, not knowing if the first was defective. After installing and using DANCO waterproof grease on the O-rings to make it easier to install, the shower faucet is still dripping. Any ideas.

  • Ed January 24, 2015, 10:49 AM

    You have a very informative site. Thank you!
    I tried to fix a leak in my delta faucet and after removing screw with Allen wrench the handle body would not separate from the stem unit with adequate pull. Any tips?

  • Sandi January 27, 2015, 11:27 PM

    I have an older Delta T2710 brass roman style faucet with matching sink and shower faucets. One of the sink faucets was leaking and when my husband took it apart a piece broke. It is a discontinued line so we thought we would replace all the fixtures. Decided on the Delta Lahara series in champagne bronze. I have ordered the sink faucets first and am waiting for them now. I wasn’t sure if I needed new rough in cartridges or not so contacted Delta. After several back and forth emails, I have found out that I am unable to replace the T2710 for the tub because the drilled holes in the fiberglass tub are too large for any other trim kit. Is there not something I can do to make these holes smaller so I can replace the tub faucets? I have not been able to find the replacement brass faucet for the sink anywhere. I don’t want the same faucets anyway, they are really out of date and I never did like them. I don’t want to get a whole new tub either. Any suggestions?

  • SG January 30, 2015, 5:42 PM

    Most reputable companies’s faucets (Delta, Moen, etc) come with a lifetime warranty on the parts. If you know the model of your faucet, its pretty straightforward and they will send you replacement parts for free. If you don’t know the model, you can use the “faucet finder” links on their websites to find your model, or send them a picture and they will help. The only downside is you will have to wait for the parts to arrive, but then you get expensive parts like cartridges, for free!

    • Dane October 30, 2015, 12:20 AM

  • Mimi March 17, 2015, 7:03 PM

    Thank you for all the information here–this is not a 5 minute job! Delta faucet will not stop running after all parts (including cartridge/spark plug thing) replaced. We have turned it every way–180, 90, 360–but upside down. Nothing will stop the steady stream of water when we turn the water back on. I think we have the wrong size–is that possible? We even put the old parts back in thinking it would stop the water and we would have the leak–it didn’t. Now I have a leak and steady stream of hot water unless I turn the water off behind the sink. So somewhere we have something backward, but I can not figure out what!! Help!! Thanks!

    • Jeff Patterson March 19, 2015, 4:50 AM

      Sorry to hear about you problem Mimi, that stinks. It sounds like you have seats and springs. Is your spring oriented the correct way? By that I mean the tapered end faces upward. If the tapered end of the spring faces downward into the faucet and you place the rubber seat over it your faucet will leak regardless of how the cartridge is positioned. But of course, you want cartridge installed the right way, too.

  • Iqbal June 23, 2015, 5:15 PM

    Thank you for all the information here, Really appreciate it !

    I have this unique issue , When I turn on my COLD water , the faucet is leaking from under the handle of HOT water handle.

    And When I turn my HOT water handle , there is no leak under the HOT or COLD water handle .

    What do you suspect ? Is this a cartridge issue but with which handle., HOT or COLD ?



    • Dane October 30, 2015, 12:19 AM

      It’s probably the O ring on the hot side. When you do these repairs Delta recommends doing both handles/sides at once because if one goes bad the other is surely not far behind.

  • David Bernick July 16, 2015, 6:11 PM

    Thank you so much for the photos and descriptions ! I was in a hurry and didn’t pay attention as I was dissembling mine and was miffed as to which way the spring went into the seat. After viewing your page, it took me 2 min to put it all back together!!!

  • angie October 11, 2015, 3:32 PM

    Hi Jeff

    I did this in three of my bathrooms. On the fourth, after I was done, even though the handle is in off position the water stays on after putting all together
    Any ideas?

    • Jeff Patterson October 11, 2015, 4:16 PM

      Hey Angie, it sounds like the cartridge may have been installed backwards. Check if that’s the case and simple reverse it, 180 degrees πŸ˜€

  • Will October 20, 2015, 7:51 PM

    Thanks for the great instructions and pictures…made this home repair on my seats and springs a breeze!

  • Larry Lancaster October 29, 2015, 6:16 PM

    Just finished fixing our Delta bathroom faucet. Took me about thirty-minutes to do the job, thanks to your great instructions! I too was a little puzzled about the spring/washer (how to set it correctly), but read the comments and saw the answer. Anyway, great job. I would be messing with this for a full afternoon if not for your help.

  • Dane October 30, 2015, 12:18 AM

    I’ve followed this procedure on both handles and the faucet started leaking from the aerator again in about a week. Delta suggested I had to flush the lines with the stems and seats/springs removed. Funny, because they don’t mention that anywhere in the article on fixing a leak. I have a sneaking suspicion they’ll start leaking again in another week after I flush the faucet/lines/etc. Is my only recourse to buy a new faucet? I can’t imagine the life expectancy of a $300 delta faucet is 8 years.

  • Kal Lauter November 2, 2015, 3:38 AM

    I had a leak from the aerator of the faucet. Took the whole faucet out of the sink and took it to Lowes to see what parts I needed. They recommended seat and springs. Took me awhile to figure out where these were located and I managed to get one side (hot side) fixed. Then when I tried to do the other side and put it back in the sink and turned everything on, I got a leak from the base where the water turn off valve is. So I took it apart again and it looked like the seat wasn’t seated in the hole. Took me another hour to coerce, coax, cajole the spring/seat into the hole. Then when I turned it on, no leak from the faucet, but still leaking from the turn off value. So what is causing this? Does this mean the seat thing is still not in the hole well enough or do I have a leaky water value?

  • Marcia November 20, 2015, 10:42 AM

    I have been dealing with a leaky kitchen faucet. It’s a Peerless, and I’ve been in the house 15 years now, never changed anything on it. I got the cartridges out and took them to the hardware store. The clerk told me I needed the Delta replacement part made by Danco, #10474, 3S-16H/C which compares to Delta RP25513. I don’t know anything else about my faucet except it’s a Peerless. The faucet still leaks when I put the cartridges in. The left one works with a small leak. The right one gushes, lol. When I stand the old cartridge next to the new one, the new one is just a mm taller it seems. Is that why it’s not working right?

  • Sara December 24, 2015, 12:39 AM

    Thanks for the tutorial, I have fixed my leak using a cartridge from the same faucet that I had in another bathroom that I replaced though still good. I fixed the leak but my handl turns backwards instead of forwards. I tried turning the cartridge 180 degrees but the it turns in from forward position to towards the faucet. Still wron way. Is this because I used the cartridge from the cold handle to fix the leak in the hot handle? Or is it something else? Thanks!


    • Jeff Patterson December 26, 2015, 4:53 PM

      If I had to guess Sara your cartridge configuration is simply off. You’ll have to take a look at the half moon shape on the bottom and make sure it’s lined up over the faucet hole when the handle is in the ‘off’ position. Starting there will help get the handle back to normal…but let me know if you have any questions

  • Tom January 6, 2016, 4:04 PM

    Replaced the spring and washer on the hot water side of a horizontal Delta shower setup. No more leaks, but the knob now works in reverse. Water runs when it’s turned clockwise and turns off counterclockwise. Help!

    • Jeff Patterson January 7, 2016, 5:44 AM

      Hey Tom, thanks for your question. It sounds like the cartridge orientation is off a bit. You’ll need to shut the water off and spin the cartridge 180 degrees.

      I also answered your question in my podcast (episode 219)

      You can listen to it here


      But let me know if you have questions πŸ˜€

  • Mike March 14, 2016, 5:25 PM

    Just wanted to get some input on your thoughts Jeff.
    I have a older delta bathroom faucet system but it uses the same cartridge and stem and rubber gasket and spring in your original video.

    Over the years and specially here recently the hot side has started to eat the rubber gaskets up like crazy im talking I have to replace it every three months and have become quite a pro at it, I can do one in less than three minutes now. lol

    I have replaced the entire unit / cartridge several times and im sure not to over tighten the unit, just snug and I also have found that using silicone grease helps everything move smoother and gives me a extra few weeks of use verses when I dont use grease.
    But my question is why does my hot rubber gaskets wear out so dang fast?
    The inside is clean as can be, no deposits what so ever and I make sure that during installation every thing is perfectly clean and percise.
    I have a friend who was a plumber for over 20 years and even he was bum founded, he watched me install it once one time and even he said I was doing a percise job and he couldnt figure out why the gaskets were going bad so fast either.
    He double checked my pressure on the tightening to make good and sure I was just going snug and one time we even broke out a digital torque wrench to make sure neither of us was going to tight.
    He said its one of those things were he would rip the unit out and replace it because something wasnt fitting right but I noticed one thing that might point us in the right direction.
    If I turn the temp of my hot water heater down to its lowest setting the gaskets will last six months.
    Any Advice?

    • Jeff Patterson March 16, 2016, 5:08 AM

      Great questions Mike and I can possibly help with this detective work.

      First, it could be the water pressure.

      If your pressure is over 80 psi then the seats will wear out faster than if the water pressure was less than 80 psi.

      Buy a $10 water pressure gauge and test it over night. Attach the gauge to a hose bib outside or inside…laundry tub would be a good place.

      Do it over night since water pressure spikes around 2-3 am.

      If the pressure is over 80 psi you can either adjust or replace your water pressure regulator or add one.

      Second, it could be chemicals that the water treatment facility is adding.

      This year my plumber has replaced more pipes due to pinhole leaks and they blame the new chemicals at the water treatment plant…kinda scary.

      In that case you could add a water filtration system. I’m seriously considering this at my house!!!

      Let me know if this helps πŸ™‚

      • Mike Bisch April 11, 2016, 5:51 PM

        Well several weeks later and here were are again. lol
        Time to replace the little fart again.
        I did test the water pressure several times over the course of four weeks to see if we could get a spike and its at a perfect 66psi low with a normal median of 69psi and 72 was the highest spike at my main into my house so im satisfied to say that’s pretty darn good and reliable pressure if you ask me.
        I did some research and I do know that The Louisville Kentucky Water company is supposed to have one of the top ten cleanest water supplies in the U.S. so that leads me to think about chemicals in the water now, after all how else do you have that clean of water.
        My only reasoning for ruling out chemical is that the rest of the faucets in the hose used to be the same as the one in the bath tube the trouble maker and no of them ever had any issues like this one.
        The hot water heater is a fairly new 3 year old 50 gallon gas heated smart water heater.
        While im leaning towards ripping the tub unit out and giving up, it would be nice to solve the mystery.
        I just wonder if anyone has ever had this issue before.
        I do know when I rip this guy out im gonna do some measurements with a caliper and mic and see if I can compare to some others but as for now im all out guesses.

  • Heather March 16, 2016, 3:40 PM

    Thx for the easy to use instructions! I was so nervous, but your directions were spot on and the pictures and video made it sooooo easy! What was I waiting for. Thank You!

    I like the flow chart the best.

  • Dani March 20, 2016, 9:25 PM

    Hi, I can’t seem to get the spring out– the seat came out easily but the spring seems really stuck. Tried needle nose pliers etc. Could it be that the wrong spring was put in?

  • Steve March 21, 2016, 11:58 AM

    Really poor design by Delta. That spot where the set screw is located gets full of all kinds of crud. I cleaned it out, but even after that I can’t move that set screw with the allen wrench. Tried WD40 and Liquid Wrench but no luck. Do I have to replace the faucet just to fix a leak?? Really, Delta needs to punish that designer buy sending him/her to every house with a leaky faucet to do the repair.

    Any ideas on loosening that screw?


    • dani March 21, 2016, 1:10 PM

      Sometimes a vinegar soaked rag can get rid of mineral deposits. I would try that

  • Eric May 2, 2016, 8:13 PM


    We had a leaking bathtub faucet. I decided to replace the “bonnets” springs, and seat on both sides.

    It seems we did everything correctly. The leak has stopped! However, when we put the lever handles back on and turn on the water, we cannot completely shut off the water using the levers. Perhaps we can half shut off the water, but not completely. When we take off the levers and just adjust the plastic top of bonnets, we can shut off the water. All this seems to imply we are not seating the levers correctly, but at the moment we are stumped as to how to do this.
