Concrete Spa Fitting - Water Air Jet Mixer

Concrete spa fitting — water/air jet mixer (venturi tee) for spa and jacuzzi pools, solvent-welded to a 1.5 inch pipe. Pressurised water from the spa pump passes through the venturi, draws air in from the air line and delivers the aerated stream to the jet nozzle for the hydro-massage effect. Cast one mixer into the spa wall behind each jet position, connect the top port to the air line fed by the air controller, and keep all jets on one pump within a 1.5–2 m pipe run of each other so they deliver evenly.
