Typical Installation

The legacy FloodMaster RS-090 is most commonly installed in conjunction with residential washing machines, in-line between the hot and cold water faucets and the water line connections on the washer. While typical installations have a manual lever for water flow shut-off, these require hands-on action to shut down the water flow. If no one is home when a leak occurs, the resulting water damage can be catastrophic! The FloodMaster system provides constant monitoring and automatic water shutoff when leaking water comes in contact with the sensor puck. Place the sensor on the floor near or under the washer where water is likely to accumulate during a leak, and we’ll take care of the rest!
