I have a shutoff valve that gets a pin size amount of a water bubble around one spot of the threads on the inlet side when I run a few minutes of hot water to the sink. It does not leak any other time. Do I dare attempt to tighten the nut (probably compression) or leave it alone as there is no steady leak?
Actually, I am confused as to why it would only leak once the pipe heats up with a run of hot water?
Thanks for your time and input.
