My water line going to the dishwasher was leaking so I replaced it. Now I've figured out that the shut off valve is leaking at the nut that goes over top of the PVC pipe. I bought a replacement valve but can't figure out how to get the old one off the PVC pipe. I'm assuming it has glue/cement inside holding it on. How can I get that off?

Thanks!

Does your shut off valve look like this? (see image)

Nope, it's straight. The water would be going straight through and the turning thing is on the side.

Is it metal or plastic? How about this one?"(see image)

The shut off valve is metal. The guy at Lowe's gave me the new one to replace it with that has a piece of PVC coming out of the metal part that I'd insert into the supply PVC and cement together, then the nut screws back on that. Seems pretty easy, but I just can't figure out how to get the old one off.

It looks like this... and I've drawn a dotted line to show where the new one has the inner pvc that I'm supposed to glue to the existing pipe.

If I understand you right...

We don't use pvc for water anywhere around here that I know of... CPVC... but not pvc.

But if you are sure you have pvc pipe there...

You just need to CUT the old pvc pipe/nut off (use hacksaw) and then prime/cement the pvc adapter with nut onto cut pipe.

Let dry as directed on cement can and then install/tighten (use two pair pliers... hold against yourself).

That sound reasonable.. Let us know... Mark
