Elbow Trap (J Bend) # P-53408B

An Elbow Trap, also called a J-Bend, is a U- or J-shaped bend in the plumbing under a sink. Its purpose is to create a natural spot to form a clog, so when a clog does form, it is in a convenient location to clean out. If the elbow trap were not there, the clog might occur farther down the piping, behind a wall or under a floor, where it would be harder to get to. Elbow traps also catch wedding rings, contact lenses, plastic caps, and other small things you might accidentally drop into the sink. Chances are the lost item won't make it past the elbow trap if you shut off the water right away, and can be retrieved by removing the trap.
