Combined bath fill and overflow fitting with shower option

摘要

The fitting has an anti-siphon device (1-3) set below the level of the upper edge (22) of the bath. The anti-siphon device is in the form of a free flow stretch (2) of at least 20 mm laterally off-set above a drain funnel (14) or next to the overflow hole (20) between the back of the bath tub and its tile cover. The mixer supply nozzle and the re-entry or diversion bore (8) are set at the end of the free flow section so that when the water is sucked back from the filled bath through the re-entry or diversion bore the supply nozzle lies outside of the returning water stream. The axes of the nozzle and bore corresponding to the flow direction of the water are angled at about 30 deg. to each other.
