In a spa tank, a flexible exhaust water tube pivoting in a vertical plane exhausting a massaging water stream on the back of the user. The assembly is adjustable to govern rate of whipping of the exhaust tube and nozzle. The nozzle is buoyant and adds air to the exhaust water stream. Low-wear roller abutments are pressed by the exhaust water tube as bend points in undulating reversal movements at the top and bottom of the pivotal movement of the tube.

The improvement in a spa or the like that includes a tank containing water for body immersion and a flexible exhaust tube directed to exhaust water into said tank from a side thereof and a source of pressurized water connected to said exhaust tube, said exhaust tube having a free end adapted to whip by reaction to water exhausting therefrom and guide means guiding said exhaust tube to swing substantially in a single vertical plane, the improvement, comprising: (a) a nozzle secured to said free end of said exhaust tube and an air line secured to said nozzle and extending generally parallel to said exhaust tube, (b) said nozzle being formed by a larger rigid tube and end plugs for said larger tube, a smaller tube extending through said larger tube and openings in said plugs to pass said smaller tube, the free end of said exhaust tube being secured to said smaller tube, said air line connecting to said larger rigid tube at a location alongside said smaller tube and said smaller tube having side ports whereby the inside of said larger tube forms a floatation chamber receiving air from said air tube and exhausting air from said chamber in a Venturi manner through said ports into the water stream passing through said smaller tube during exhaust of pressurized water through said exhaust tube, (c) housing means for said tube including opposite sidewalls forming said guide means for said tube, (d) said tube having a fixed portion secured to said housing means with said free end extending inwardly therefrom towards the inside of said tank and means forming a pair of upper and lower abutments above and below said tube and spaced from said fixed portion of said tube in a direction toward the inside of said tank and said abutments forming bend points in undulating reversal movement of said tube at each end of the path of travel of said tube, (e) said abutments being formed by a pair of rollers, (f) said housing means including an outer housing for said tube to which said tube is secured with said free end extending inwardly therefrom towards the inside of said tank and an inner housing inside of said outer housing having opposite sidewalls forming said guide means for said tube, and (g) said housings being mounted for relative vertical adjustment therebetween to adjust for the path of travel of said free end of said tube.
