Abstract
A hydromassage fitting employs a directional nozzle to inject an aerated jet of water into the interior of a water receptacle, such as a bathtub, spa, therapy tank or swimming pool. The directional nozzle is mounted in the fitting so as permit water to drain around the nozzle and into the water receptacle when the fitting is not in use, thereby inhibiting the collection of water in the fitting. Pockets and voids within the fitting are eliminated or sealed in order to further inhibit the collection of water in the fitting.
