ABSTRACT:
An overflow pipe in a water closet supports a valve arm which carries a valve for opening and closing an outlet in the bottom of the tank. A first float is connected to the outer end of the valve arm to maintain the valve in an open position until the water level falls below a predetermined level. A second float is carried on a float arm pivoted intermediate its ends to the support. Cooperating lock means are provided on the end of the float arms opposite the float and in the travel path of the valve arm whereby a horizontally disposed pin on the valve arm is adapted to engage a horizontal surface on the adjacent end of the float arm and move therealong into locking engagement with a vertical shoulder thereby holding the valve in an open position until the water level in the tank falls below a second predetermined lower level thereby releasing the valve arm to return the valve to its closed position. A trip handle is connected to the first float for initially moving the valve to an open position.
