Abstract
A whirlpool jet for bathtubs having a water outlet extending through a circular opening in the bathtub wall and threadedly connected to a housing. The outlet has an annular radial flange abutting against the inside of the bathtub wall. The flange has a pair of diametrically spaced openings for use in rotating the water outlet in mounting the jet on a bathtub by using a circular wrench having a pair of pins which fit within the openings. The periphery of the wrench has knurling for manually rotating the wrench and a square central opening for receiving the square head of a driving tool. A jet outlet control which is rotatably mounted within the outlet has a concave area surrounding the inner end of a water passage in all rotational positions of the control, so that the water flow into the passage is constant. An extension for poured concrete installations is adapted to protrude beyond the edge of the concrete, the protruding portion being discardable.
