Stop using bread We've all tried bread to stop that annoying leak on a job. The problems with bread, and the reasons we invented Jet Swets are: 1: Bread holds almost no pressure at all. There's nothing more annoying than working on a pipe with bread in it when the bread gives way and the released water ruins your solder seal. Jet Swets hold 65 lbs. of pressure instantly and all day long! 2: You still have to wait for a long time until the water gets down to enough of a trickle where you can use bread. Jet Swets can be used instantly upon getting to the job and turning off the water. 3: When that chunk of bread finally dissolves, it gums up the fixture and valves in the system. 4: It just looks unprofessional.
