Floodstop V4 Dual Valve Automatic Water Shut Off for Sinks

FloodstopSKU: FS38CD-V4



FloodStop automatic flood prevention devices use a wired water sensor to detect a leak.  When water is sensed, the FloodStop controller automatically closes the water valve to help avoid devastating water damage.  At the same time an alarm sounds.

The FloodStop V4 3/8" Dual Valve model is designed for sinks so that it shuts off both the hot and cold water lines in case of a leak.

The FloodStop V4 controller can be powered with the included plug-in power supply with 4 C batteries as a back up instead of power failure.  Or where a receptacle isn't available for power, it can be run batteries only.  Full time power is recommended where available.

The FloodStop controller has a built in "normally open" relay that closes when triggered.  This relay output can be connected to an auto dialer, alarm system or automation system.
