Abstract
A fluid regulator (1) for use as a shower water saving device, wherein an initial volume of water of a water stream at an undesired cold temperature is collected in a chamber and is reintroduced into the water stream when the stream has reached the desired temperature. Reintroduction of the initial volume of cold water is at a controlled rate such that the temperature change upon reintroduction is not significant. The fluid regulator (1) comprises a body (2), a flow passage (3) having an inlet (20) and outlet (21) for the water stream, a water collection chamber (4) in fluid communication with the flow passage (3), and a flow diverter (5) associated with the flow passage (3) and moveable between a closed position in which the water stream is directed to the collection chamber (4), and an open position in which the water stream may flow to the outlet (21) and the water in the collection chamber (4) may be drained from the collection chamber (4) to the outlet (21) by way of the flow passage (3).
