Abstract
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.
