Whirlpool WPW10116738 Siphon Break Elbow for Washer

The Whirlpool WPW10116738 Washer Siphon Break Elbow is a critical component used in washer/dryer combos to prevent the entry of sewer gases into the laundry area. This L-shaped plastic piece connects the drain hose to the washer's internal drainage system. It is designed to retain a small amount of water within its structure, creating a barrier that stops sewer gases from traveling back through the drain pipe. As the washing machine drains, the retained water exits through the elbow and into the drain pipe. This water barrier is important due to the potential hazards and odors associated with sewer gases. Additionally, in certain washing machine models, the siphon break is essential for the proper functioning of the vent system.
