Water Heater Leak Alarm & Shut-Off Systems

Water heater and water tank failures can happen at any time, often without warning, and can cause substantial flooding and property damage if a leak goes undetected. Reliance Detection Technologies has options for you. The RS-074 and RS-094 series water heater leak alarm and automatic shut-off systems are ideal for minimizing water damage when these failures occur – even in plenum spaces.

The commercial grade FloodMaster RS-094 valve can be simply installed to the feed water line for the water tank and the sensor placed on the floor, in a pan near the pressure relief valve drain tube, or in a position where the leaking water would first appear. When the water sensor detects leaking water, the system will sound an alarm and automatically shut off the feed water intake to the tank to minimize water damage.

The RS-074 is an economical solution for any home. The battery-operated shut-off unit is installed on the cold-water feed line, and the attached water sensor is placed at the base of the tank. If the sensor detects a leak, an alarm sounds and the valve automatically closes to prevent extensive flooding and water damage.
