Hi All I just discovered a slow leak at the hot water pipe on the water heater, the plumber installed 2 yrs ago but looks like a bad soldering job. The leak is very, very small, I only own a butane torch for building brass frames for slot cars, could it be used on this joint? I was thinking of putting some flux on it and heating it till the existing solder flows right. Would that work? I never worked with copper pipe before.
TIA
