ABSTRACT:
A diaphragm controlled toilet bowl valve of simple construction that is substantially silent in operation, will not permit water to be siphoned from the tank in which it is disposed during an emergency in which the pressure of water in the supply lines decreases substantially, and one in which the actuating float is easily adjusted without hindering or deforming the rod on which it is supported.
