  • Multiple valve assembly for reducing water loss from a leak
    Patent number: 8166998
    Abstract: A valve assembly for reducing water loss from a leak from a water device. The valve assembly includes a first passage through which water flows from a water source to the water device and a second passage through which water flows from the water device. A first valve is in fluid communication with the first passage and the second passage. The first valve is operable for obstructing the first passage in response to a change in pressure differential between water in the first passage and water in the second passage resulting from a leak of water from the water device. The valve assembly also includes a second valve in fluid communication with the first passage. The second valve is responsive to the obstruction of the first passage to close the first passage and thereby stop water from flowing from the water source to the water device.
