ABSTRACT:
An overflow system is described for a water receptacle (22) such as bathtub, sink or washbasin having a water tap for connection to a water supply. The system includes sensing means, such as a float (14), for sensing an overflow condition of the receptacle, and a supply valve (65) responsive to the sensing means and arranged to close the water supply to the tap. The supply valve may be hydraulically controllable via a control port (68) thereof. A control valve (59) is provided between the water supply and the control port The control valve is responsive to the sensing means so that upon such an overflow condition it open and the pressure of the water supply is applied to close the supply valve. Thus, there is no need for a supply of electricity.
