RS-094 Hot Water Heater Leak Shut-Off

A leaking water heater can keep receiving water long after a problem begins. The FloodMaster RS-094 pairs a wired water sensor with an automatic shut-off valve: when the sensor detects water, the system sounds an alarm and closes the water supply to the tank.

How it works

Position the sensor in the drain pan or the area beneath the water heater where a leak would collect. When water reaches the sensor, the system activates the alarm and shut-off valve. Once the leak has been addressed, the system can be manually reset for continued use.

Choose your valve size

• RS-094-1/2: ½-inch valve
• RS-094-3/4: ¾-inch valve
• RS-094-1: 1-inch valve
• RS-094-1-1/4: 1¼-inch valve

Have your installer confirm the supply-line size and installation requirements before ordering.
