FloodMaster RS-094 Water Heater Leak Alarm with Automatic Shut-Off

Proven, effective protection for water heaters. This compact shut-off valve sounds an alarm and stops the water when a leak is detected. No Wi-Fi, no subscriptions. Choose the valve size that matches your water heater supply line: ½", ¾", 1" or 1¼".

• Magnetized leak sensor sits directly in the drain pan or under the tank with a 1/16" stand-off to reduce false alarms caused by humidity
• Audible alarm sounds when water is detected
• Sensor installs securely using the included metal plate, horizontal or vertical

• Plugs into a standard wall outlet, no special wiring required
