ABSTRACT:
A water supply installation such as a mixing valve (11) has a cold supply (13) and a hot supply (12). An outlet (14) is controlled by a valve (15) and in order that the temperature of the installation (11) can be raised after closure of the valve (15), means, such as an isolating solenoid valve (20) is provided which isolates the cold supply (13) from the body of the installation so that the body of the installation is supplied only with hot water after switching off, the rise in temperature being effective to prevent and or discourage growth of dangerous bacteria.
