My plumber fitted a compression isolation valve under the bath for me. The joint was weeping very slowly so he tightened the nut. But I later noticed water built up on the nut. The water wasn’t enough to be an issue, so I left it to deal with later. Now a week later, the joint seems to have dried and no more weeping is present.
Should I now not bother with putting any ptfe tape, as the joint seems to be sealed? Or could the seal be temporary and should I apply some ptfe to the olive and re-tighten it?
