摘要： A water distribution system protects against water leaks by shutting off the water if a pre-determined flow is detected for more than a set period of time. The time may be changed to any value between one minute and four or more hours. When the pre-determined flow continues past the set time, the main shut off will activate for two seconds, closing the system.

摘要： A water shut-off valve assembly comprises a valve that is moveable by a motor between open and closed positions. The water shut-off valve assembly is adapted to be connected to a water line. A sensor is also associated with a valve assembly for sensing leakages that occurred downstream from the valve assembly. A controller is operatively connected to the water shut-off valve assembly for actuating the electric motor which in turn actuates the valve therein. From time to time, the water shut-off valve assembly exercises or moves the valve within the valve assembly so as to prevent the valve from becoming clogged due to inactivity over a period of time.
