I have this valve under my sink that is meant for a dishwasher, but it has a weird size to the outlet and its old, and I want to replace it. The two lines above this one lead into the sink (hot/cold)
A few specific questions:
- Is the water supply line going into it a PEX supply line or pvc? I'm not sure how to tell.
- Is what is there currently there compression with a ferrule? What can I expect to see when I remove it?
- Can I, should I, reuse the ferrule (if that's what is under this old one)? If not what is the safe way to remove it without damaging the pipe?
- What should I do if I reach some point of no return and can't attach a valve? I don't want to leave my house's water off forever, and because of covid calling a plumber CAN happen but I want to try and prevent that. Can I cap it off temporarily if something goes wrong?
- Is there a specific type of valve I should get? I know quarter turn are preferred. I also don't want to get the wrong kind of connection for this kind of supply line
Edit: I realize I have another question about this same valve, but that question was "what kind of outlet fitting can I get" and the answer was "you probably can't get it, so replace it". This question is about replacing it without making a mess of things, because its hard to tell what kind of pipe is there (appears to be painted copper)
