This FloodStop unit can hook up to your Sensaphone or home security system to alert you that it was activated!

Easily prevent water damage from leaking water heaters, water softeners, or even the water main! This unit will detect a leak, sound an alarm, and automatically turn off the water supply to the offending appliance or pipe to prevent further damage. Powered by AC adapter/Transformer and 4 AA Batteries as a battery backup in case of a power outage, or the batteries may serve as the sole power source if there’s no nearby electrical outlet to utilize the transformer. The controller will beep to alert you of low or no batteries. The controller has "one" output contact (normally open) that can be connected to an Alarm, Home Automation or Auto-Dialer systems if desired.

How FloodStop (FS 1/2-NPT) Works:

• The FloodStop valve is installed between the appliance (water heaters, water softeners, or water main) and its manual shutoff valve.
• Water/leak sensor is placed at the base of the water heaters, water softeners, or water main
• Valve stays open until water loss is detected
• Water on sensor closes FloodStop valve and sounds alarm
• Valve stays closed until problem is attended to and system is reset
