Question for Plumbers and those in home construction.

[McDad]

I've got failing 3/4 CPVC coupling joints under my house. There isnt much play in the pipe and its brittle (21 years old). Cant just add another coupling without risking damage elsewhere.
I can repair with 4 90 elbows and a 3 lengths of new cpvc.
I can use a slip coupling (I think; never used before).

Which should I do?

Is there another method not mentioned?

Thanks.

Simple easy fix, if you don’t want to redo the entire piece.

Re-plumb

Wreck it out back until you've got good material.

 

[McDad]

Ok. For really reelz, I'm not going to replumb all the hot and cold supply lines unless I absolutely must. I've got 3 leaky joints. There's no need in getting all extra with the job.

PEX and SharkBite fittings????

If you are planning to stay in your house for another 4-5 years, re-plumb the entire house. CPVC piping is terrible and you probably have more problems than you think.

I'll not do it unless absolutely necessary. 2 story house with 5 bathrooms. Even if I replumbed underneath, I'm not tearing into walls to replace.

I’ve just witnessed the damage from those brittle leaking pipes in some of my wife’s properties. They have had to re-plumb entire complexes.

CPVC should last 50 years+ perhaps the wrong adhesive was used?
I probably would not replace inside pipes right now, but if you start having problems inside---

it should but there was a lot made in China and not to spec.

I get it. I've had some catastrophic failures at my duplex with cpvc.

The pipe is fine. The weak areas come at the joints, rough-in fittings, and where it's prone to be struck with something unintentionally.

The leaky points are all along two lines. I suspect the installer was rushing or running low on pipe cement or something.

I am surprised at how patent the pipes are after 21 years. No build up of minerals at all.
