valves. Pipe fittings fully WRAS approved.

The control unit can be located in any convenient place, in a cupboard or mounted on the wall near the valve/s, the sleek design is a double-gang faceplate that blends into any decor. A range of optional leak detection sensors are available to be connected to the control unit for additional coverage.
