A low gravity fed water system includes a housing having an inlet opening, a portion of the inlet opening disposed above the waterline and a portion of the inlet opening disposed below the waterline. The housing has an outlet opening disposed in the housing below the waterline in fluid communication with the plurality of jets. The housing has a vent opening disposed in the housing below the waterline. An upwardly-extending conduct is connectable at a first end to the vent opening, and has a second end disposed above the waterline in ambient air away from an inside surface of the housing and away from an inside surface of the tub. In the event of a blockage of the inlet opening, air is drawn into the housing via the conduit inhibiting a suction being drawn on the inlet opening. |
