    • A low gravity fed water system (200) includes a housing (202) having an inlet opening (204), 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 (271) disposed in the housing below the waterline. An upwardly-extending conduct (270) is connectable at a first end (271) to the vent opening, and has a second end (274) 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.
    • 低重力给水系统(200)包括具有入口开口(204)的壳体(202),设置在水线上方的入口开口的一部分和设置在水线下方的入口开口的一部分。 壳体具有设置在水线下方的与多个喷射流体连通的壳体内的出口。 壳体具有设置在水线下方的壳体中的通气口(271)。 向上延伸的导体(270)可在第一端(271)连接到通气口,并且具有设置在水线上方的环境空气中远离壳体的内表面并远离内部的第二端(274) 浴缸表面。 在入口开口堵塞的情况下,空气经由管道被吸入壳体中,从而阻止在入口开口处抽吸。
