Abstract: A tap mounting (11) for mounting a tap to a plumbing fixture (66), the plumbing fixture having a surface with an aperture (64). The tap mounting (11) comprises an over-surface mounting part (12), an under-surface mounting part (13) defining a threaded aperture (58), a threaded elongate member (40) and a second elongate member (28). In use the over-surface mounting part is above the surface of the plumbing fixture, the under-surface mounting part is below the surface of the plumbing fixture. The elongate members extend from the over-surface mounting part through the plumbing fixture aperture and the threaded elongate member passes through the threaded aperture of the under-surface mounting part. Rotation of the under-surface mounting part is prevented by the second elongate member. The threaded elongate member comprises an internal bore and is configured for connection to a hose.

Abstract: An electronic control and dosing system for desalinators (10) has a baffle, disposed between the evaporation and condensation chambers, fitted with probes (70, 71) which detect the presence of liquid created by entrained bubbles, that pass through the holes in the baffle. A control circuit (72), connected to the probes (70,71), closes a solenoid valve (62) to shut off the supply of feed water to the desalinator (10) until the threat of entrainment has passed. A foaming and/or scale inhibiting polymer, contained in a tank (64), is periodically introduced to the feed water inlet line (63) by a solenoid valve (65) controlled by a timer circuit (66).

Abstract: A reversible, self-priming rotary pump has a housing with a stator of elastomeric material which is softer than the elastomeric material of the rotor on a cam on shaft. The inlet and exhaust ports are separated by a lobe received in a recess in the stator. As the shaft is rotated, the rotor orbits within the stator to pump the fluid between the inlet and exhaust ports, the stator being at least partially compressed along the line of contact with the rotor to form an efficient seal therebetween.
