ABSTRACT:
A water supply system for supplying water at a substantially constant low pressure. The system includes a reservoir with an inlet for high pressure water and an outlet for lower pressure water. An equalising valve assembly is coupled to the inlet. The valve assembly has a plurality of passages each of which is individually closed or opened by controlled valve means according to prescribed water level limits in the reservoir. The passages can be progressively opened so as to admit high pressure water to the reservoir on low pressure water draw off and can be progressively closed as the reservoir is filled.
