  • Water conservation system for home installation
    Patent number: 5465434
    Abstract: A system for recycling water used in a bathtub/shower is disclosed. The system alternatively directs water drained from the shower or bathtub to either a recycled water storage tank or a sewer line. The water in the recyclable water tank is subsequently pumped to a sprinkler system or an outdoor faucet. The water is directed to either the sewer line or the storage tank through the use of a valve with a first inlet for accepting water from the drain of the bathtub, a second inlet for accepting water from the overflow drain of the bathtub, a first outlet leading to the sewer line, and a second outlet leading to the recycled water storage tank. The valve is operative for blocking either the first inlet, the first outlet or the said second outlet only, and all other parts remain open. The position of a rotatable element of the valve is controlled by a lever mounted on the bathtub overflow plate.
