Disclosed is a flushing system for a plurality of urinal and/or toilet fixtures. The flushing system includes a plurality of flush valves with each connected to the supply water of one of the fixtures. Also included is a plurality of control stops with each connected to the supply water of one of the flush valves. Each flush valve has a threshold inlet supply pressure during increasing supply pressures at which the flush valve operates from closed to open position. The threshold pressure of at least a first of the plurality of control stops being different from the threshold pressure of at least a second of the plurality of control stops. Also disclosed is a method of operating a bank of flush valves supplying a plurality of plumbing fixtures following a water supply pressure interruption. The method including opening a plurality of control stops connected to the flush valves in a non-simultaneous sequence in response to increasing water supply pressure. |
