ABSTRACT:
A toilet having a water inlet valve apparatus has a flush tank with a water inlet tube connecting from a water source into the flush tank. A water cutoff is attached to the water inlet tube and has a valve seat in a floating valve element positioned in the water inlet tube to seat in the valve seat responsive to water in the water inlet tube so that the water is cut off from entering the toilet tank when the valve element is seated in the valve seat. A removably attached ballcock valve assembly is removably attached to the water cutoff valve and water inlet tube and has a valve opening member positioned to hold the floating valve element in the water cutoff valve from the valve seat when the ballcock valve is attached to the water cutoff valve. Removing the ballcock valve from the water cutoff valve closes the water cutoff valve and stops the flow of water into the tank from the water inlet tube. The ballcock valve includes a floating valve element mounted in the valve body beneath a valve seat so that water from the inlet valve pushes the floating valve element into the valve seat to cut off the water entering the flush tank. A float is mounted to a pair of movable arms which are connected to a cam positioned over the valve seat of the ballcock valve assembly such that the falling float will rotate the cam to push the floating valve element off the valve seat to allow the filling of the flush tank.
