ABSTRACT:
A bubble jet fitting for use in a pool or spa provides for a lay-length short enough to allow its installation within a six-inch dam wall. The bubble jet fitting has an outlet portion which in one use provides for solvent welding therein of either one of two different standard sizes of PVC pipe. An axially extending annular recess of the fitting may receive a surfacing layer of plaster or fiberglass to form a water-tight interface with the surrounding wall of the pool or spa.
