Abstract

A toilet tank flush valve for use in the demand mode, and which includes a discharge control and closure valve for controlling the flow of water from the tank or reservoir to the bowl, and with the valve further having a generally cylindrical configuration with an open top and a closed bottom defining a water retaining chamber, with the chamber extending upwardly above the discharge drain opening and being designed to retain a fill of a certain first quantity of water. Pivotal opening of the valve, while tipping a portion of the water outwardly of the enclosure, will not discharge more than about 70% of the volume of water retained within the enclosure so as to permit a more positive seal of the valve onto the discharge drain opening. A stopper installed in the end of the tubing that goes into the hole in the standpipe from the ballcock or a plastic tubing stopper with an internal bore that fits on the fitting on the top of the ballcock outlet stops a large amount of water from going into the toilet bowl through the standpipe by about 60% saving. The toilet tank water level guage allows the operater of the toilet to know when to release the flush lever on the toilet tank when the collar or washer goes down with the rod and rests on the top of the rod guide to shut off the water from going out of the toilet tank through the drain at the bottom of the toilet tank when there is enough water going out of the toilet tank to get a flush.

In combination with a toilet tank having a water reservoir covered by a tank lid, a water supply line coupled to said tank a discharge drain opening for delivering water from said reservoir to the toilet bowl disposed therebeneath, a ball cock valve controlling the flow, of water from said supply line to said reservoir, a stand-pipe fill tube extending from said ball cock valve to said stand-pipe and a water impervious discharge control and closure valve for controlling the flow of water from said reservoir to said discharge drain, the improvement comprising:

(a) said discharge control and closure valve having a generally cylindrical configuration with an open top and a closed bottom defining a water retaining chamber having an upstanding wall, and with the outer diameter of said chamber being such that the inner diameter of said discharge drain opening is immediately adjacent thereto when said valve is closed to define a sealing surface,
(b) said discharge control and closure valve being adapted to pivot upwardly about pivot points disposed laterally away from said sealing surface, and with the height of said chamber being sufficient to retain at least about 70% of the volume of water of said chamber therewithin whenever said discharge control and closure valve is pivoted upwardly for opening said discharge drain opening;
(c) a stopper installed in an end of said fill tube so as to prevent at least a portion of fill water from passing therethrough;
(d) a water level indicator gauge comprising a float having one end of an upstanding rod attached thereto, the other end of said rod having an adjustable collar attached thereto;
(e) said tank lid being provided with an opening therethrough for passage of said rod and a rod guide in alignment with said opening, wherein said adjustable collar may be placed on said rod at a position such that upon descent of said float and rod with descent of water in said tank, said collar upon touching said rod guide will indicate the amount of water drained from said tank.
