Abstract: A pillar sink mixer has a hot water faucet pillar, a cold water faucet pillar, a mixing chamber and a diverter valve to supply mixed water to a faucet nozzle or to a hand spray. The mixing chamber and diverter valve are positioned in a bridge above a mounting surface, and a passage, providing fluid communication with the hand spray device, being incorporated within the bridge and a faucet pillar.

Abstract: A diverter valve comprises a housing having inlets, a first outlet, and a second outlet. The inlets are connected to hot and cold water supplies, and mixing of the hot and cold water occurs both inside the housing and inside a mixing chamber external to the valve. The first outlet is connected to a spout, and the second outlet is connected to a spray unit. A valve element is mounted in the housing, movable between a closed position and an open position with respect to the first outlet. A piston member comprising a first piston at the bottom end of the valve element, and a second smaller piston at the top end of the valve is responsive to pressure differential between the second outlet and the inlet for movement to a first and second position. When a lower pressure exists at the second outlet, the piston member moves to the second position, closing off the first outlet. The valve also includes a flow regulator to regulate the flow through the second outlet.

Abstract: A towel rail (2) is assembled in modular format by having a plurality of individual pipes (4) selectively connectable with a plurality of discrete connecting pieces (6). The ends of the pipes (4) may have a chamfered recess (22) to enable a grub screw (20) to rigidly hold each pipe (4) in fluid-tight contact with a respective connector (6).

Abstract: A mixer tap unit has a body connected to a nozzle having two separate water passages extending the length of the nozzle. A hot water connection, a cold water connection and a filtered water connection are provided for the body. In use, the hot and cold water can mix in a mixing chamber in the tap body and flow along the passage. Filtered water flows separately along the passage. Valves are provided to respectively control the flow of the hot, cold and filtered water. In a preferred form, a chamber allows carbonization of the filtered water prior to delivery to the tap body and the supply of CO.sub.2 gas to the chamber is controllable by a valve. The valve is operated in a first direction to inject CO.sub.2 gas into water in the chamber, and in a second direction to allow the carbonated water to flow to the nozzle.
