Patent ID: 8769733

Claim:
A hydrotherapy system for treating a plurality of body zones, comprising: a plurality of fixed-temperature water sources, each water source providing water with a temperature different from other water sources; a plurality of on-off solenoid valves, the on-off solenoid valves being arranged in sets, with all valves in each set being connected by pipes to a single one of the water sources; a plurality of nozzles, with a nozzle for each body zone; a plurality of pipes, each pipe connecting the on-off solenoid valve sets to the nozzles so that, for each body zone, one and only one on-off solenoid valve in each on-off solenoid valve set is connected to the nozzle for that body zone in order to combine water streams from selected water sources and apply the combined stream to that body zone; and means for opening and closing selected ones of the plurality of on-off solenoid valves to provide water streams simultaneously to each body zone in a pattern of temperature and flow rates that changes over time.
