Water heater and water tank failures can happen at any time, often without warning, and can cause substantial flooding and property damage if nobody is nearby to detect the leak right away. When tanks are in the space between the structural ceiling and the dropped ceiling, the scale of the damage from an undetected leak can be even greater.
FloodMaster’s RS-094-MK6 Water Heater Leak Alarm and Automatic Shut-Off Kit with step-down transformer and plenum-rated wires is ideal for minimizing water damage when these failures occur in plenum spaces. Simply install the FloodMaster valve to the feed water line for the water tank and place the sensor puck on, under or near the tank, in a pan near the pressure relief valve drain tube or in a position where the leaking water would first accumulate. Wire the actuator to the provided step-down transformer (120, 208 or 240 VAC to 24 VAC) for power. When the FloodMaster sensor detects leaking water, the system will automatically shut off the feed water intake and sound an audible alarm. This closed-loop system disables the cold water supply line to hot water tanks or similar applications with basic plumbing installation.
