Abstract
A hygienic water jet assembly for a spa includes a body having a conical jet outlet that receives pressurized water and air from suitable sources. A control insert is disposed within the conical jet outlet and spaced therefrom by a gap, such that the control insert serves to combine the water and air together for delivery to a jet nozzle carried by the control insert. The control insert also includes a pair of conical surfaces that allows residual water within the control insert to drain by gravity out of the control insert through apertures disposed therethrough. The water draining out of the control insert is then permitted to drain out of the jet nozzle via the gap by gravity.
