I replaced the supply valve on my bathroom sink with this ¼-turn angle valve.
Both valves (hot and cold) are leaking about 1 drop every few seconds at the valve's input. I got them hand tight, then added about 2 full turns with a wrench. Should I tighten them more, or are they leaking because of over-tightening?
Before installing the valve, I shined the copper pipe with scotch brite, and I put 3 wraps of PTFE tape on the male threads. I am reusing the nut and ferrule that was there.
