This demonstration uses a Moen valve and trim, but the principles are similiar for other single-handle units. Although this set-up uses copper for the supply pipes, your system may use CPVC or PEX. Although they present their own challenges, installs with those materials are generally easier. Feel free to comment with any questions!

Nice guy, soft spoken, yet terse.

Excellent! Thank you

Nice to know that there are repair sleeves for copper pipe. That would make it easier to do. Thank you for this information.

@shelbymarieclohossey 4 года назад

I have access from behind. I dont have the width that you had behind. The elbows are right next to the existing valve with little to no space between the joint. My new valve is larger. Am I going to have to add pipe to space them out around the new valve? Can they be on an angle bowing out or do the have to run straight?

@Teach2Build 4 года назад

A lot of that depends on whether you're using copper or pex. It can be challenging when things are a tight fit, but with the right fittings and a dose of patience, you can do this. Best of luck!

@JRS-iq9pz 4 года назад

You can't unsolder the pipes and re-attach them with a new shower control?

@Teach2Build 4 года назад

You can, but it's not as easy as it sounds. You have to get the pipe very clean of existing solder in order to get it inserted in the new valve, and that involves heating and wiping while it's still hot enough for the solder to flow. It can be done that way, though, yes.

No water coming out of the faucet.

@Teach2Build 3 года назад

Oh man. That's a bummer, with lots of potential causes. If it's a recent development, you probably need a replacement cartridge. Best of luck!

@charlescoates5761 2 года назад

Why don't you just replace the cartridge that takes care of all those issues

@jonwesley1885 2 года назад

I've had two of these valves fail, that were less than 12 years old. The brass part of the valve cracked at a seam. Replacing the cartridge wouldn't help I'm afraid. I'd love to know how old valves lasted a lifetime and the new stuff breaks in 11 years ? I don't want to disparage a brand but it rhymes with Owen :)

My 25 yrs old Moen shower valve had to be replaced, but it got stuck and I struggled to get it out, the cold and hot CPVC lines snapped, didn't know what to do, emergency call to plumber who placed 2 sharkbite caps to stop the flow so I can turn the water back on in the house. I am in the middle of replacing it myself, got a quote for $1500 (part+labor). I called Moen, their stuff is lifetime warranty, they sent me a free replacement posi-temp valve. I purchased a few things I didn't have (torch, copper fittings & pipe, sharkebite fittings, pex-A pipe, pex-a expansion tool) I accessed the valve from the back, added an access panel for future use, added 2 ball valves (pex-a). I'm still not done completely, I take my time, it's great to have another shower I can use. Quite a project, will have some tile work to do too, but I'm confident this will save me a bunch.

@rejeanpaquet4375 stories like yours inspire us all to tackle that project, and save a little money along the way. Thanks for sharing, and take care!

@gadasavideos8564 5 месяцев назад

Why are you slip coupler. Couldn't you move uprights enough to fit regular coupler?

@Teach2Build 5 месяцев назад

You often can, yes, but moving the ends that way risks damage to the pipes. Lots to consider.

@mikebrabant4170 4 года назад

I had to access my valve from the tub side and that meant knocking out three wall tiles to gain enough room to replace the valve with a new one, a bit of a messy job but had no choice. Have to replace the tiles and cement board also. But it was all done but took some time to complete.

@Teach2Build 4 года назад

Those can be tough. Search Amazon for a "remodel shower plate" and see if one of those might cover the hole. They look nice and can save a lot of hassle. Best of luck on your project!

@SadChadrick Год назад

160-300$? Man, thats a grand in WA now. Great video. Super helpful and clear. Awesome content.

@Teach2Build Год назад

Yeah, pricing didn't age well. Pretty big jumps in cost since this video was produced 12 years ago...

@gadasavideos8564 5 месяцев назад

Why change it? Why not just replace the cartridge ?

@Teach2Build 5 месяцев назад

That's definitely the cost-effective way to go, but sometimes folks want a fresh look they can't get with the current mixing valve. Also, occasionally, a bad cartridge will m pretty much weld itself in there.

@maddawgzzzz Месяц назад

You don’t want your old faucet from the 90s hanging around lol

@gadasavideos8564 5 месяцев назад

Water hammer arrestors not required?

@Teach2Build 5 месяцев назад

While always a good idea, if you're replacing an existing mixing valve, you may not be looking to try to add them. They're simple enough, but would add a lot of complexity to this job. I always add them, though, if it's plumbed in copper or CPVC. If is plumbed in PEX, I skip them as they're unnecessary due to the PEX ability to absorb water hammer.

Thank you so much, you're a great instructor

@RLH007 3 года назад

Got enough solder bud?

@Teach2Build 3 года назад

Right? As I mentioned, my joints aren't exactly gorgeous, but they're tight. And they never leak due to not enough solder, that's for sure.

@williamd2451 3 года назад

Did he really apply the flux inside the pipe 🤦‍♂️

@Teach2Build 3 года назад

Nope. It goes on the outside of the pipe and the inside of fittings.

@bobnethery5488 3 года назад

Excellent.

@thecommonsenseconservative5576 3 года назад

So I am assuming you can't just replace the valve at the threads you have to sweat in new pipes or can you do it just at the threads

@Teach2Build 3 года назад

Hello! The problem is that you can't turn the fittings without cutting the copper. Therefore, you could choose to cut the copper just back from the fitting, replace the valve, then reattach the copper by soldering in new couplings.

@thecommonsenseconservative5576 3 года назад

@@Teach2Build gotcha. That's kind of what I was figuring. There is no access to the back through a closet or anything so this isn't looking great. THANK YOU THOUGH FOR THE QUICK RESPONSE!!

Sounds like you have your work cut out for you. Best of luck!
