Abstract

A water hydrant valve (10) comprising a hollow body portion (12) with a water inlet (44) and a water outlet (46 and a sealing member (16) arranged to move between the water inlet (44) and the water outlet (46). The valve (10) is arranged so when water pressure is higher in the water main (60) than the feed pipe (58) the sealing member (16) seals against the water outlet (46) and requires an actuation means (70) to open the valve, and when water pressure is higher in the feed pipe (58) than the water main (60) the sealing member (16) seals against the water inlet (44) and thus prevents backflow into the water main (60).
