Abstract: A filling system for a toilet tank prevents continual flow to the tank in the event of a leak from the tank by providing a hydraulically actuated safety valve for halting water flow to the filling valve in the event that the water flow continues for a time longer than an expected time of filling. The safety valve has a valve member connected to a piston mounted in a cylinder defining a first chamber on one side of the piston and a second chamber on the other side.
