How to Replace a Plumbing Shut-Off Valve | This Old House

[@80a7x]

I had a similar situation recently , so I called a few people off Kijiji (Canadian classified) and was quoted 250$ for a new valve , I was flabbergasted, and when told the person that estimate seemed steep, they were very offended....in conclusion , I bought a new valve for about 15$ from home Depot . Thank you again for the great content :)

[@beantown_billy2405]

That's about what it costs for a plumber to come out and do an hour job

[@pgreenx]

⁠@@beantown_billy2405I agree with you. I am not a plumber but everyone with a good skill set needs to make a living and the fee includes traveling to the home, time to purchase the replacement valve, the expertise etc. same goes for me as a CPA and people complain about when I do a tax return for my fee.

[@GWoldstuff]

After you cut the pipe make markings at 1/2 inch and at 3/4 of an inch away from each cut. Once the valve is in position you can only guess that you are grabbing enough pipe on each side. .the black marks will come in handy then

[@andrewthomas9602]

I know this video is 10 years old, but dang I need some help from the This Old House team. My wife, son, daughter, and I recently moved from a tiny cabin starter home out to a historic 100+ year old home in peanut farmin’ Wakefield VA. It was a dream home for us and we still can’t believe we are in it now, but knew it would come with some surprises. It has original slate roof (with a bunch of leaks in attic I found out!), some old school wiring in places, and copper water pipes and endless corroded shutoff valves EVERYWHERE! I’m honestly sketched out a leak will spring any moment, or there already are pinholes I don’t even know about yet. Wondering if I should get ahead of it and start proactively swapping with something more modern as I’m able to get materials. FYI I am extremely thankful and appreciative for all your videos and work. I’ve learned a lot from your show, going back to watching in middle and high school shop class.

Ball valve are more expensive the a regular valve. It might run as much as $2.00 more in so stores! Stick with replacing it with the same type of valve unless money is no object or you have a million dollar home.

[@stashorama]

I saw this segment years ago. I don't know why anyone would replace an existing stop valve that has soldered connections with stop valve with compression connections when some simple maintenance would have sufficed. He should have shown the homeowner how to replace the faucet washer and add to or replace the stem packing. And then, gave him advice on how to snug-up the packing nut as needed instead of letting it leak from the stem for years as evidenced by the build-up of green copper corrosion and calcium on the exterior of original valve.

How do you deal with the situation of not having any play in the pipe? In the video there was a lot of play so one could just insert the new valve into the existing pipe, that doesn't work so well when there is zero play in the pipe on either side of the existing valve. With PVC they have an extending coupling to deal with the situation, haven't seen anything like that for copper.

you'd have to add additional pipe with a coupler.

Should hand tighten those compression nuts and then do about a half a turn. turn water on and test. if it leaks go another 1/4 or as necessary to stop it. Usually a 1/4 to 1/2 turn after hand tight is enough. Overtightening a compression fitting is suboptimal and not recommended.

[@Nativtexan2]

It's called sand cloth and found in the plumbing area. It doesn't have a grit number like what you use for wood.

[@YouTubestopsharingmyrealname]

it's emery cloth which is aluminum oxide abrasive glued to fabric. for copper pipe you'd use 120 to 180 grit

[@namrednop]

I've always used what's called crocus cloth on copper pipe. It'll really clean-up copper pipe really slick and pretty. It's an abrasive sheet (You can also buy it in a roll) that's similar to sandpaper (Closer to emery cloth), but covered with a layer of very fine, loose, iron oxide particles rather than with an abrasive like sandpaper.

[@rawbacon]

I used one 20 some years ago at my Dad's place when the main shut off was still dripping and I couldn't solder.

[@justenhansen]

I did this exactly but it leaks because the ferrule curled around the end of the pipe. Make sure the ferrule slides completely on to the pipe and doesn't overhang. I think the only way this method will work is if your pipe has a little play so you can close the gap a little. My pipes are fixed so this method doesn't work.

[@gmoneyb5559]

Justen Hansen yep. You have to make sure both ends of copper pipe are fully seated into the valve then compress nuts

[@Free-g8r]

You can try wrapping the ferrule with Teflon tape. I find that works like magic whenever I have a leaky compression connection

[@bobbaker9230]

Heh, I just learned this the hard way. Was trying to avoid using a torch in the location I'm working as I have very little space, but the pipe has no play and the gap is too large to get a decent seal. Tried the teflon, but it still drips as the ferrule still gets pulled past the edge of the pipe when I tighten. Looking around hoping I can find another valve with just a tiny longer width, but it doesn't look like that exists. I keep getting recommended shark bite instead, might have to resort to that instead.

[@PaulbylPaulbyl]

Aren't the pipes on opposite sides of the new valve pulling outward? Long term will that unseat the ferrell seals?

[@workingshlub8861]

compression fittings are fine if done correctly...make sure they are accessible and not hidden in walls etc.. and make sure pipes are well supported and not flapping around..wont have problems.

[@AStanton1966]

I would put a little pipe tread sealer on all ferrules for a little added measure. You can also put it on Teflon tape.

[@rocketrider1405]

how many teeth per inch should the minihacksaw have to cut through the copper pipe?

[@richardtuhro2955]

it is often best to have several teeth of the saw engage the cross section you are cutting. for the relatively thin copper pipe this would require many teeth per inch. 32 might be close, but if you cant find one that fine use as many as you can get.

You would need to solder on an extension, or do a Sharkbite install.

Shark bite has a slip install so it is not a fixed length. That may be needed if the pipes are fixed. But you need to move the pipe slightly to get it on.

[@frankjames1955]

some times logic doesn't make it into code as it SHOULD.. a compression is better down in the basement where drains are and because they can be tweaked to stop leaking in a moments notice where as other leaking joints can not be serviced so easily behind closed walls etc. another example of code failure is concerning the requirements for apartments and condos to have only metal drains under the kitchen abd bathroom sinks , based on fire safety concerns..yet most cupboards are made of combustible woods and material and most folks store plastics containers and combustibles under their sink, likewise forbidding ABS pipe isn't logical at all.. in fact ABS pipe outlasts the metal counterparts and is more leak proof.

[@mrbig4532]

Timothy Champagne you need to find two threads in the area of the old valve , so the old valve will unscrew that’s one thread than you have to replace the pipe down to the next thread in line. Once you have two threads than you screw on a thread ball valve , they are the best valve out there and they work for your lifetime, second go to the second thread and screw on a copper female adapter with a piece of copper already soldered Into the adapter, and than screw a copper male adapter into the house side of new valve with a piece of copper soldered onto that fitting also and you want your two new pieces of copper that are not threaded to butt up against each other , than just put a copper coupler on the ends of the new copper and solder that last fitting.

[@linkinprk1981]

Many old houses have galvanized steel supply lines well before copper was common practice. When possible (access and financial means), it's best to replace all of the old pipes because the old pipes will rust up and give you hard water and rust stains as they age. You just have to make sure you use a brass or dielectric connection between the old and new pipes or you'll have a bad time (bad chemical reactions between zinc and copper)

[@mrbig4532]

Timothy Champagne galvanized pipe doesn’t rust that’s why it’s acceptable to use for potable water.

Shark bites don't hold on copper if there is a freeze. They pop right off.

[@BobbieGWhiz]

I just did this project, but was concerned about the extra longitudinal tension put on the pipes because of the loss of pipe length from sawing out the valve. It made me feel uncomfortable that it might pull out of the compression fitting someday, or leak at some nearby joint. So I added a Sharkbite slip fitting to extend the pipe. No leaks and no tension. I’m thinking of buying a WiFi water leak sensor for further peace of mind. I just found out that my water heater is 17 years old. Yikes! I won’t be doing that one on my own.

[@MontageCenter1]

Steve Kunkel when you place the valve handle down it increases the chance of debris settling in the valve which could potentially cause the valve to not close when needed. However in this situation since he used a shutoff that has the drain on it, placing the valve handle upwards renders the drain useless. Placing it on the side usually makes it so little to no debris settles in the valve, and then the drain would work the way it were designed.

This is great when you have a lot of space, my pipe had less than an inch clearance. There should be more conditioning of the pipe and deburring the inside.

I'm pretty sure it would work if the valve wasn't so tight for space.

[@AStanton1966]

The first time I replaced one of these valves and tried sweating it, it ended up like the Three Stooges--water everywhere. Luckily I was able to get a plumber before the wife got home to cook dinner.

its not good practice to use a hacksaw on an old water line (like the one in the video) you could shake it too much and break a fitting down the line also the stop and waste you pulled out was installed correctly with the drain facing down so you can drain the pipe completely the way you installed the new one when its used to drain will leave water in the bottom of the pipe
