I'm replacing the shut-off valves, supply lines, and the faucet they connect to and I'm having an issue with one of the shut-off valves.
The shut-off valve is a brass (BrassCraft) quarter turn angle valve with a compression ring/nut and I'm connecting it to 1/2" copper pipe (from the wall).
For the first valve (the hot one), I removed the old valve (the compression ring puller I bought worked like a charm), installed the new one, and then tightened it until it stopped leaking. Everything worked great!
For the second valve (the cold one), I followed the same process, but I was never able to get it to stop leaking. I'd check it, tighten it about 1/4 turn, then check again, and I repeated that process until I started to see the brass compression ring sticking out behind the non-threaded side (wall side) of the compression nut. For comparison, this second compression nut is screwed on MUCH further than the one on the first (non-leaky) valve.
After taking the valve all the way off, the compression ring is practically embedded in the copper pipe.
Any ideas on how to proceed? I'm suspicious that the compression nut has been over-tightened (at least, I'm afraid to tighten it any further).
Should the compression ring be embedded so far into the copper pipe that I can't remove it (even with my compression ring/nut puller)? Am I going to need to cut off the end of the pipe and try again with a new compression fitting?
The good news is that the leak is pretty slow (maybe 1 drop per minute), so I have some time to plan my next move
Thanks in advance!
