Patent ID: 8096891

Claim:
A hydraulic system for a water ride, comprising: a first primary pump hydraulically connected to a first supply conduit so that the first primary pump delivers pressurized water to the first supply conduit; a second primary pump hydraulically connected to a second supply conduit so that the second primary pump delivers pressurized water to the second supply conduit; the first and second primary pumps and first and second supply conduits arranged so that a flow of pressurized water from the first primary pump to the first conduit is isolated from a flow of pressurized water from the second primary pump to the second conduit; an auxiliary pump; a pump bypass manifold; and a plurality of valves; wherein the valves are arranged relative to the pumps and manifold so that, through selective actuation of the valves, the first primary pump can selectively be disconnected from the first conduit and in its place the auxiliary pump can be selectively connected via the pump bypass manifold to the first conduit so that the auxiliary pump delivers pressurized water to the first conduit in place of the first primary pump and a flow of pressurized water from the auxiliary pump to the first conduit is isolated from the flow of pressurized water from the second primary pump to the second conduit.
