FloodStop is a point-of-use leak detection device that automatically shuts off the water supply to an appliance or fixture the moment a leak is detected. Once water is detected, the motorized ball valves close and sound an alarm. FloodStop is a durable and multi-use device, which limits potentially devastating flood damage, allowing the plumber, builder, and homeowner to have peace-of-mind knowing no flood caused by an appliance or fixture will go unnoticed. STOP FLOOD DAMAGE BEFORE IT EVER STARTS.
