The HydroStopper is a patented device, which closes the flow of water to the washing machine, when it detects any water underneath the washing machine, from either a leak in one of the hoses, or the washing machine.

The HydroStopper is mounted between the faucet and the hose, and has a sensor placed on the floor.

As soon as water reaches the sensor, the HydroStopper closes the water supply.
