Leak Detectors/Automatic Shutoff valves

Floodstop products are designed to protect your home or business from costly water damage BEFORE it becomes a problem. In addition to sounding an alarm when a water leak is detected, the FloodStop line features automatic water shut-off valves to protect you. Appliances develop mechanical failures, and water-lines and hoses can burst from normal everyday use. Each FloodStop product is an easily installed appliance-specific or whole house (water main) solution depending on the model. Its just a matter of time appliances in your home will leak and they will cause damage.


Water Heaters have a limited life, then leak after years of corrosion. Water Heaters are generally considered a maintenance-free appliance, but they are also one of the single most damaging appliances in the home.

Since they are continually under pressure, even small pressurized leaks can quickly flood and devastate a home. Whether at home, at work, or on vacation these flooding events can go undetected for hours or even days.

The FloodStop kit automatically shuts off the water supply to the Water Heater and sounds an alarm, leaving all other household fixtures and appliances operational.

Washing Machine related flooding can happen at any time, from hoses with ruptures or cracked fittings, to internal failures from clamps, valves, pumps, drains and failed switches.

Floodstop Washing Machine models automatically shut off hot and cold water to only the washing machine. Sounds an alarm. All other household plumbing fixtures and appliances are unaffected. Unlike expensive "Whole-House" water shut off systems that are expensive require professional installation, these "Point-of-Use" systems are affordable and easily installed

The kit contains everything you need to protect your property:

  • Two 3/4" motorized ball valves with hose fittings to install on both hot and cold water inlets.
  • Water sensor to place on the floor. If there is a washing machine drain pan, purchase another sensor to place inside pan.
  • The Control Unit to be mounted with screws or Velcro (included). AC Adapter and/or batteries for power source.

Burst pipes can happen anywhere, anytime

There are additional Floodstop models for:

  • Dishwashers
  • Refrigerator ice maker & water lines
  • Sinks
  • Toilets
  • Inside & Outside Water lines


Additional Sensors can be added to any Floodstop model by wiring one sensor to another in a chain format. There is no max # of sensors.

How FloodStop Works:

  • The FloodStop valve is connected to the supply line

  • Water/leak sensor is placed at the base of the appliance

  • 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
