  • Water shut-off valve and control system
    Patent number: 5794653
    Abstract: 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.
