Abstract
A swimming pool aerator is designed with a base member secured to the end of a water return pipe above the water surface in the side of a pool or water feature basin. The base member carries a retractable spray nozzle, which normally is biased to retract into the wall of the pool through the base member. When water is applied to the supply line under pressure, an aerator nozzle is moved from a rest position to an extended position against the action of a biasing spring to spray water into the pool. When the pressure or supply is turned off, the aerator nozzle is retracted back into the base portion by the biasing spring to a position safely out of the way of swimmers or users of the pool.
