Washing Machine Leak Detection & Automatic Water Shut-Off System with Integrated Outlet Box

Model RS-090-E

The RS-090-E is a complete, installation-ready solution for managing and reducing losses caused by washing machine failures. Washing machine leaks and burst hoses can quickly overcome floor drains and catch pans, causing thousands of dollars in water damage in a short amount of time. The threat is compounded when units are located on upper floors and in apartment buildings.

The system consists of an outlet box with built-in leak detection receiver for simultaneous automatic hot and cold water shut-off. The RS-090-E kit also includes pre-installed water hammer arrestors on both the hot and cold water lines and a water leak detection sensor which sits on the floor next to or under the washer. System installation is easy with provided mounting straps and trim plate. The system works off standard 120V AC wall power – no hard wiring required.

When the sensor detects a leak, the system will signal both the hot and cold feed lines to automatically close. The red LED lights up and an audible alarm sounds. The easy push-button reset restores the water flow after the leak has been addressed.
