ABSTRACT:
Water leak detection and prevention systems and methods in which water is only delivered to the water pipes in the building when a faucet or appliance demands water and water is delivered through a normally closed shut off water valve. During the period that the main water is shut off, the water pressure in the water pipes is continuously monitored to detect a water leak in the building. Detection of a leak causes an alarm to be sounded and a continued closure of the shut off valve.
