I have a leaky 1/4 turn angle compression stop valve under the lavatory sink. When I tried to tighten it up (using two crescent wrenches) the leak got bigger. I shut off the main and removed the screw-out part of the valve to find that the male threads had split. I installed a new valve, using the old nut and ferrule, but the same thing happened again. I tried NOT to overtighten it, but it leaked a bit, so I tightened it some more, and it leaked even worse. I assume the valve threads are split again, but I swear I did not "gorilla" tighten this valve.
In order to try to remove the old nut and ferrule, I have to cut open the back of the vanity to get to them. Could using teflon tape on the male threads of the valve prevent it from leaking if the ferrule has become deformed a bit?
Can someone explain what else might be going on here?
