How To Repair a Galvanized Pipe Using Dresser Couplings
Dresser couplings are a style of repair coupling used to
splice plumbing pipes. They are used on galvanized, pvc, and abs drainage
lines, copper water lines, pvc and cpvc water lines, and galvanized water lines.
If a water line freezes and breaks, you may not be able to repair it with a
brass compression fitting or a fitting from the same material as the pipe. In a
case like this, try a Dresser coupling. Sometimes on old galvanized water lines
the threads are corroded to the point of uselessness and you cannot rethread
the pipe. You may be able to use a Dresser coupling here to repair the line if
it is not corroded as well.
