ABSTRACT:
A water conservation system for toilets is provided. The system comprises an auxiliary water supply including a storage tank for collecting and storing recycled or gray water and a water line hydraulically connecting the storage tank to a toilet tank. A dual action valve is disposed in the toilet tank. The valve includes a first valve segment connected to the fresh water supply and a second valve segment connected to the water line from the storage tank. One or two floats, which are responsive to the fill level in the toilet tank, open and close the first and second valves. The dual action valve may further include a pilot valve disposed inline between the fresh water supply and the first valve for switching the fresh water supply regardless of whether the first valve is in a closed or open condition. The pilot valve communicates with the water line from the storage tank and is responsive to pressure in the water line.
