Abstract: A hydrotherapy return fitting is described composed of a fitting body with a waterflow passge through it that is connected to a water circulation pump. The return fitting is suitably held within an opening bored in the wall of the tub or spa and a removable decorative liner or cover of tubular shape is provided within the interior of the fitting. It has a circular peripherally extending flange which covers portions of the fitting in the interior of the tub. A manually removable screen is provided inside the decorative liner and a handle is provided on the screen so that it can be easily grasped. A suction relief valve communicates between the atmosphere and the passage through the water return fitting to permit air to enter when the return fitting is plugged breaking the suction and allowing the object to be removed.

Abstract: A hydrotherapy system is described in which a movable nozzle with a fluid inlet and outlet pivots about a center point enabling the outlet to be pointed in different directions. A water stream flows toward the passage in the nozzle. The system contains an air inlet and an air outlet passage with a valve chamber communicating between them within the nozzle housing. An air and water check valve moves in the valve chamber to an open or sealed position to allow the passage of air into the chamber but prevents the escape of water.
