Whirlpool WP356471 Siphon Break Cap for Washer

The Whirlpool WP356471 Washer Siphon Break Cap is a small plastic component that is installed on the input pipe of the washing machine. This part plays a role in the water delivery system during wash cycles. It creates an air gap between the end of the hose and the water level inside the washer, which helps prevent the backflow of contaminated water into the clean water supply. This design addresses the issue of siphoning that can occur due to pressure changes, where dirty water could otherwise be drawn back into the clean water line. The siphon break cap is an important part of the washing machine's operation, ensuring separation between contaminated and clean water sources.
