: Much cheaper solution. Plug the pipe with some cheap paste bread (Wonder – type bread). It will hod the water back, allowing you to sweat the joint, then dissolve when you turn the water back on. Works every time.: PS I am sure regular bakery bread will work too, but make sure you donot use crust. Paste bread seems to dissolve better.This bread thing drives me crazy.Im a professional, never have I or never will I use bread. If you know what your doing its easy.
