  • Universal toilet tank shut-off assembly
    Patent number: 4633534
    Abstract: A universal shut-off device for stopping the flow of water from a toilet tank to a toilet bowl during the flushing of the toilet. The device is mountable on toilet tanks having a handle on either the right-hand side or the left hand-side of the tank. The device has a stop handle accessible from the exterior of the toilet tank. If the plumbing is partially or completely plugged up and the toilet bowl begins to overflow during flushing, the flow of water into the bowl can immediately be shut off during the flushing operation. This is carried out by turning a stop handle which causes the tank ball to move against the valve seat and stop the flow of water from the toilet tank to the toilet bowl. A bendable and ductile operator arm is shaped by the user to push against the tank ball.
