Abstract
A pliable hinged nonbuoyant flapper valve having a frusto conical projection for centering the valve in relation to a toilet drain, and for permitting the flapper valve to contact a toilet drain valve along a continuous line of engagement of seal the toilet valve. A chain connects the flapper valve to a toilet control lever. A ball float having a positive buoyancy slightly greater than the mass of the flapper valve is interposed an an adjusted location between the lever and the flapper valve for holding the flapper valve in an opened position to allow a predetermined volume of water to flow through the toilet drain.
Claims9
A toilet water saving device comprising:
- a pliable hinged non buoyant flapper valve including a sealing surface having a frusto conical projection for registering said valve in relation to a toilet drain and for permitting said flapper valve to contact sealingly a toilet drain valve seat along a continuous line of engagement;
- a chain connecting said flapper valve to a toilet control lever;
- a ball float interposed on said chain between said lever and said flapper valve for holding said flapper valve in an opened position to allow a predetermined volume of water to flow through said drain, said float having a positive buoyancy slightly greater than the mass of said flapper valve;
- and
- means for fixing frictionally said float at an adjusted position on said chain wherein said float includes an axially disposed round tube for disposition therethrough of said chain and said fixing means includes a pliant O-ring disposed within said tube for frictionally engaging said chain.
A method of using a toilet water saving device having a pliable hinged non buoyant flapper valve including a sealing surface having a frusto conical projection for registering said valve in relation to a toilet drain and for permitting said flapper valve to contact sealingly a toilet drain valve seat along a continuous line of engagement, a chain connecting said flapper valve to a toilet control lever, a ball float interposed on said chain between said lever and said flapper valve for holding said flapper valve in an opened position to allow a predetermined volume of water to flow through said drain, said float having a positive buoyancy slightly greater than the mass of said flapper valve, and means for fixing frictionally said float at an adjusted position on said chain wherein said float includes an axially disposed round tube for disposition therethrough of said chain and said fixing means includes a pliant O-ring disposed within said tube for frictionally engaging said chain comprising:
- determining a suitable water volume for each flush;
- connecting the flapper valve to a toilet control lever;
- pivotally connecting the flapper valve to a toilet refill tube;
- and
- locating the float between the flapper valve and the lever wherein said locating includes positioning said float for delivery of the determined water volume.
