FloodStop leak detection devices automatically shut off the water supply to your washer, sink, water heater, dishwasher and more the moment a leak is detected. As soon as the sensors detect water, the motorized ball valves turn off the water supply and give out an audible sound. FloodStop devices limit the potentially devastating issues that can be caused by a large leak or flood, thus allowing the plumber, builder, and homeowner to have peace-of-mind knowing their fixtures and appliances are protected, saving potentially thousands of dollars in home repairs.
