Abstract
The toilet water saver includes a toilet tank and flushing valve assembly that efficiently uses the water in the tank for the particular waste being flushed. The flushing valve assembly has two flapper valves, one flapper valve disposed vertically higher than the other, and an actuator that operates one valve singly or both flapper valves simultaneously at the user's option. The disposition of the valves with respect to the maximum tank capacity level defines respective first and second volumes of water to be used. The higher disposed flapper valve is operated to drain a smaller volume of water for the common liquid wastes while the lower disposed flapper valve is operated to drain a much greater volume for solid waste.
Claims7
A toilet water saver, comprising:
- a toilet tank adapted for holding water for flushing a toilet bowl, the tank having an outlet adapted for connection to a toilet bowl;
- a water refill assembly extending into the tank, the refill assembly being adapted for maintaining the flush water at a predetermined level in the tank;
- a flush valve assembly having:
- a valve body including an elongated pipe having at an upper end at a first differential depth below the predetermined water level and a lower end connected to the tank outlet;
- a first flapper valve disposed at the upper end of the valve body, the first flapper valve permitting a first volume of flush water to pass through the valve body and the tank outlet when the first flapper valve is in an open position, the first volume of flush water being defined by the first differential depth and being adequate to flush liquid waste from the toilet bowl;
- and
- a second flapper valve disposed adjacent the lower end of the valve body pipe, the second flapper valve being disposed at a second differential depth below the predetermined water level, the second flapper valve permitting a second volume of flush water to pass through the valve body and the tank outlet when the first and second flapper valves are simultaneously in the open position, the second flush volume being defined by the second differential depth and being adequate to flush both liquid and solid waste from the toilet bowl;
- and
- an actuator for selectively actuating either the first flapper valve alone or both the first and the second flapper valves simultaneously at a user's option.
