Hydro-massage tub control system

A hydro-massage apparatus comprising:

• a tub having wall and a drain opening;
• a pump with an inlet connected to the drain opening and having an outlet;
• a nozzle assembly located in the wall of said tub to direct a flow of water into the tub;
• a valve connecting the outlet of said pump to said nozzle assembly;
• a pillow removeably attached over said nozzle assembly;
• and
• a control mechanism for detecting an absence of said pillow from said nozzle assembly and closing said valve in the absence of said pillow.

A hydro-massage apparatus comprising:

• a tub having a wall at one end and having a drain opening;
• a pump having an inlet connected to the drain opening and having a pump outlet;
• a first pulser mechanism having a inlet and a plurality of outlets, said first pulser directing a pulse of water sequentially through each one of the plurality of outlets;
• a first valve coupling the pump outlet to the inlet of said first pulser mechanism;
• a plurality of nozzles located in the wall of said tub to direct a flow of water against a back of a bather sitting in said tub, and each one of said plurality of nozzles being connected to a different one of the plurality of outlets of said first pulser mechanism;
• a water outlet in the wall of said tub above the plurality nozzles;
• a pillow covering said water outlet;
• a second valve coupling the pump outlet to said water outlet;
• a second pulser mechanism connected in series with said second valve between the pump outlet of said water outlet to pulsate water flowing therebetween;
• a controller having a first mode of operation in which only the first valve is open so that water flows only through said plurality of nozzles, a second mode of operation in which only the second valve is open so that water flows only through said water outlet, and a third mode in which both the first and second valves are open so that water flows through said plurality of nozzles and said water outlet.
