A control stop (16) for a flush valve (22) for a urinal or toilet fixture includes a housing (28) defining a flow chamber (38) divided by a valve seat (42) into inlet (44) and outlet (46) sections. A valve structure (54) is biased toward the valve seat (42) by a spring (78) applying a valve closing spring force. The housing (28) is sealed by a diaphragm (70), and the diaphragm covers the movable valve structure (54), isolating it from water flowing through the housing. The diaphragm (70) does not impede valve structure movement, and the closing spring force establishes a threshold water supply pressure for opening the control stop (16) during increasing pressure following a no or low supply pressure condition. A plurality of control stops (16A 16H) may supply a bank of flush valves (22A - 22H) and fixtures, and open in a cascading sequence during increasing pressure as a result of having springs with different closing spring forces.
