Customer Questions and Answers for Washer Siphon Break Kit by Whirlpool

This siphon break kit installs on the washer's drain hose connection to prevent water from siphoning back into the machine during a wash cycle. It acts as a one-way valve that allows water to drain out while stopping reverse flow. Replace this kit if your washer drains water unexpectedly, fills slowly, or if you notice water siphoning back into the tub after it has been pumped out.
