How to Install a Water Shut Off Valve

Water leaks!!

If there’s ever a time to freak out it’s during a water leak.

They lead to damaged drywall, mold, etc etc.

Nasty stuff can happen as a result.

Shut off valves can help prevent this from happening.

I’m currently remodeling a bathroom in one of my rentals.

The shower needed a shut off valve, so…

Today you’ll learn how to install a water shut off valve in a shower or tub.

You’ll also save about $100-$125 by not calling a someone else to do this for you!!

Let’s do it.

If you’re read my tutorials on plumbing you know I Love SharkBites.

They simply push on and that’s it.

There are a few steps but not many.

I’ll show you every one of them and you can repeat what we do today.


Here are the supplies you need

By the way, this old bathroom I’m working on…I’m gonna show you all the ins and outs of the remodel.

Stay tuned.


How to Install a Water Shut Off Valve

First step, turn off the water to your house.

Usually the water main will be in a basement or garage.

Turn if off and drain your home at the lowest point.

Usually this is a laundry tub, outdoor spigot, or kitchen faucet.

Plan where you’ll place the shut off valve.

Then cut copper pipe with an AutoCut tool.

I love this little tool.

It’s great for tight spaces and slices through copper in 7-10 revolutions.

Deburr the inside of your copper pipe.

When you cut copper pipes you create a little lip.

This needs to be removed otherwise the SharkBite fitting may not work.

Use either a deburring tool on a Ridgid No. 15 pipe cutter or a utility knife.

Clean the inside and first 1 inch of the copper pipe using a cleaning tool/brush

Emery cloth also is great for cleaning the first 1 inch.

Place the SharkBite depth tool on copper pipe and make a mark 1 inch from the edge.

Now all you have to do is slide the SharkBite water shut off valve onto the pipe.


You’re done.

Well, almost done.

The final step is to test your work by slowly turning the water back on.

If all is good, you should have no leaks.

If for some reason you do have a leak, you can turn the water off and slide the SharkBite off the pipe.

I show you how to do this in my video…by the way, the house in the video was my very first rental ever.

We’ve had it for 12 years and it’s been a journey, let me tell you, haha.

Watch the video for a surprise at the end 🙂

  1. Teresa Hoye says:

    This is so great! I am getting ready to put shut off valves in both bathrooms and this would make it so easy, even I could do it. Thank you.

  2. Jeffrey Conboy says:

    I prefer to sweat pipes. I guess I am old school. But there are some tight spaces where I would consider using it where the flame of the torch could start a fire. Do they also make connectors? I hate pin hole leaks. They are usually in the hardest places to get to. Awesome idea.

  3. Renovating a basement complete with bathroom. Could use these tools during the process. Really enjoy your videos and have found numerous hints and tips. Keep up the good work.

  4. Jim Brohman says:

    I could use the tool give away because we retired and moved into an older home for financial reasons, we need to renovate the home I have started the renovations. All of the taps and shut offs leak and I am trying to repair as I go. By the way I am 71 yrs young and still renovating, many large jobs as I said the whole house needs renovations. I want to upgrade the main bathroom and install a basement bathroom for convenience. I was a home inspector …. fully qualified RHI in Ontario before I retired, I find your videos very helpful. I always research my projects before I start, you can never be over prepared.
    Thank you for all your help

  5. Peter Mazzaraco says:

    I am sort of my neighborhood handy man and I believe that kit would be a great help.

  6. Neal Cissel says:

    I watched the video on the sharkBite connection. I will be needing to do this on my hot water heater as I know I am going to need to replace it sometime this year. I hope I win
    Thanks for your DIY video’s they have been helpful to me.

  7. Sunil says:

    Hi Jeff, You made is sound so easy which it actually is and I realized it after I changed one for the first time. The key challenge for me the first time at my home was the mineral deposits around the old valve made the removal a challenge. And the valve was inside the bathroom cabinet which made it all the more inconvenient.

    After changing a few at my home, with all the required confidence I ventured to change one at one of my rental homes. Though all my prior experience came by handy, I had a new challenge. Even though the main water supply valve to the home, was fully closed, water kept oozing out when I unscrewed the old shut off valve. I had also help the taps open to drain out but this oozing would’nt stop. I then had to hurry up with changing the shut off valve while mopping up the small puddles.

    Now wondering if the main valve needs a change too. 🙂


  8. kevin ngo says:

    Touching or doing anything to a water pipe has always scared me but this video made me felt so at ease. This tutorial would come in handy since I need to tackle this at my tenant’s bathroom.
    Thank you so much.

  9. Phil McBurney says:

    Could use this kit when remodeling my daughter’s bathroom in her condo. Have used Sharkbite fitting before and love them. I haven’t seen that cutting tool before. I have a small cutting tool I use, but this looks much better.

  10. Josh Mitch says:

    What a great system! It’s hard to believe that this doesn’t leak. I’ve sweated a lot of copper joints in the past, and I’ve tell ya, I’m not real good at it – the flux always seems to burn. So I have 10 shut-off valves I have to replace (they’re too old and don’t work) and this kit would come in handy. Thanks for the opportunity to try it out without buying it first 🙂

  11. MGillman says:

    I already had shut-off valves in my bathrooms, but when I went to replace the sink, the old hot water valve (28 years old) began leaking when the copper pipe to the sink was disconnected. I installed new connectors, a new sink, new faucets, and new valves! All this after I faux-finished the existing vanity top (not a standard size). The projects were easy after viewing Jeff’s tutorials. I know Grandma can do it as I am a Grandma and 70 years old! My children are so proud because they didn’t have to drive from 4 different states to help me do this project. Looking forward to more of Jeff’s tutorials

  12. Norman says:

    I panicked when I had my last leak and the plumber took advantage of the situation. I could sure use your kit for my bathroom.

  13. Dempsey Lowe says:

    None of the shut off valves work in my house. All need replacing. Going to try replacing them after watching your very helpful video. Thank you.

  14. Paul says:

    I have changed a couple of valves in the distant past but the old way. I would love to have thses tools for my next project, though it will likely take me a little more than 9 minutes. 🙂
    Thank you for sharing.

  15. Bob says:

    As soon as my son finishes up his kitchen remodel (all done by him, his son, & the old man)… only has his flooring, and finishes to complete- He is moving on to doing he & his wife’s bathroom. Watching the video on the shut-off valves was informative & helpful to me, and I am forwarding it to my son for his bathroom. Thanks, Bob

  16. dennis allen says:

    another great video jeff. I can use a few of these. on my water heater, my main shut off valve. under all my sinks. keep up the great work.

  17. John McLaughlin says:

    H E L P !!!!!!!!!!!!!!

  18. Ed Kautz Sr says:

    Good info at the right time. I need to move my washing machine in the laundry room to make it more efficient for the wife. Found out only shut off on water in house is at the well pump entry to the house. All other faucets and bath have none. Real bother when I might have a problem. Kit would really help in moving wash machine now that your tutorial has shown me how to do it. I can then install other places too in the house as needed. Thanks for these good DIY articles. Ed

  19. Rick Stuart says:

    As you said, this is a super easy way to replace a shut off valve. I love how you break it down for us. Many thanks and hope I am the random recipient of the kit

  20. Edward Balek says:

    Getting ready to do a bathroom remodel, followed by adding an additional half bath in the basement. This kit will be a great help.

  21. Jerry Herrman says:

    I would do this myself. It looks to be easier than soldering copper pipe.

  22. Michelle Devero says:

    Thank you for your videos. I just purchased my first rental and have some projects to tackle. Hiring a handyman or contractor is a night mare. I have to replace the shut off valve in the front of the house because the knob is missing. I am hoping it will be as easy as yours. What does deburring mean? Thanks again

  23. Jim says:

    Great video, love the shark bite products, could use the kit for the toolbox. Have a rental unit and repair business too.where the kit would be useful.

  24. Mike Whaley says:

    Getting ready to add a wet bar to basement and will need these for sure. Thanks for the chance to win them.

  25. Dan says:

    There are some gate valves on the galvanized pipe that are turning blue. I fear just touching them will cause them to leak for a while until crusted over with time again? Is brass gates to galvanized even ok or will that cause electrolysis reaction? Will have to use local turn-offs like you show, Jeff. Then what to do with the old valves?

  26. If you have an older home with galvanized pipes, I suggest hiring a plumber to do the switchout. Unscrewing the old valve and screwing on a new one may seem easy enough. But if the pipe is rusted internally or the threads are rotted, this “simple” plumbing job can turn into a plumbing nightmare. If your home is plumbed with PEX or plastic pipe, these instructions don’t apply.

    1. I’d like to clarify what you said Lucy and say SharkBites can be used with PEX and CPVC, I think that’s what you were inferring in your last sentence 😉

  27. Ricky Carpenter says:

    I’m replacing the plumbing under my kitchen sink, because I apparently had a leak and the cabinet floor boards have rotted because of a leak under my sink. I am also installing SharkBites instead of trying to sweat copper pipes . I have been told that SharkBites are the way to go. I am also doing some plumbing in my shower so I want to put some shut off valves in the bathroom so that I can work on my shower if needed.
