ABSTRACT:
A hydrotherapy jet assembly includes a resilient grommet and a jet valve body. The grommet has a lip, a body having an inner surface and an outer surface, and a raised bead running the inner surface circumference. The inner surface includes a tapered portion tapering away from the lip. The jet valve body has a water entry port, an air conduit, a lip, and an external circumferential groove for interlocking with the raised bead of the grommet, and a water fitting. According to a method of the invention, the grommet is inserted from the inside of the tub through a hole drilled in a tub wall until the lip of the grommet seats flush with the tub wall. The jet valve body is inserted from the inside of tub until the bead of the grommet interlocks with the groove of the jet valve body and the lip of the jet valve body abuts the lip of the grommet. With this design and method of installation no back grinding is required of the drilled hole and no other sealant, such as a gasket, caulking, or o-ring, is required for installation. The entire installation may be completed by one person. Other embodiments of the hydrotherapy jet assembly and of other tub and pool fixtures are also provided.
