[0.5" NPT threaded fitting.] Prevent Water Heaters from flooding your property, water heaters will eventually leak after years of corrosion. Though they are generally considered maintenance-free appliances, the small pressurized leaks can quickly flood and devastate a home. The FloodStop for Water Heaters automatically shuts off the water supply to the Water Heater and sounds an alarm, leaving all other household fixtures and appliances operational. It is easily installed in fifteen minutes.

How FloodStop (FS 1/2-NPT) Works:
Simply connect the FloodStop valve between the Water Heater and manual shutoff valve, and place the water/leak sensor at the base of the water heater. When the sensor detects water, the FloodStop valve automatically closes and sounds an alarm. The valve stays closed until problem is attended to and system is reset.

Use this item for any 0.5" NPT application.
