Toilets, Sinks, Showers, Tubs and Disposals - Replacing Shut-Off Valve

I was having a leak in my upstairs sink and noticed that it was coming from where the CPVC pipe goes into the shut-off valve. In trying to tighten the valve the pipe broke off. It seemed like it already had a small crack in it. Well anyway, all of the documentation (all my books and online) show how to install a shut-off valve, but only for metal piping. How would I do it for CPVC? What type of tools, material (teflon tape?, pipe compound?) do I need and what type of procedure should I follow and does anyone have any ideas as to how I can use my water until this is done.

Use CPVC glue on a new CPVC shut-off valve.
Good Luck!

Thanks, I fixed it. I just used the same type of valve that was on there before. I don't think the type I used (and the type that are on the other sinks) are the correct type to use. They are BrassCraft metal shut-off stop compression valves. The box says to only use on copper. Is this a common practice, to use these type of valves on CPVC? I asked the guy at Home Depot and he said that the compression type was the right one. Is it better to use plastic valves?

If so I will eventually replace all of the valves with the correct type. At least the leak has been fixed for now.

The problem with using a metal compression valve (or any other metal compression fitting) on CPVC is the word "compression". When you tighten up the compression nut, it presses the ring into the surface of the pipe. Since metal is harder than plastic, it puts the plastic in a strain. This could cause a crack in the pipe. Plastic compression fittings have plastic compression rings. I,personally, am not a big fan of plastic valves. I use metal valves and male plastic adapters threaded into the valve. Just MY reasoning. Good luck.

Yeah that's what I kind of figured. Thanks for the tip. I will try that.
