Is ‘Rapid Action’ tapware suitable if there is a low-pressure hot water supply, or if the supply is from a tank or bore by means of a pressure pump?
Yes, because the design allows the full flow that is possible through the seat of the tap when the tap is fully open. Ceramic discs restrict the flow somewhat, even when the tap handle is in the fully open position. When the hot water supply is at low pressure and the cold water is at high pressure, it may be more difficult to achieve a comfortable mixture because there is not enough graduation in less than half a turn to control the high pressure water – in such a situation a conventional tap would probably be more successful.
