ABSTRACT:
A dry suction fitting assembly is provided for drawing water from a spa, whirlpool bathtub or other suitable water tub to a pump, featuring a suction body for arranging in relation to a wall of the spa, whirlpool bathtub or other suitable water tub. The suction body is arranged in relation to a wall of the spa, whirlpool bathtub or other suitable water tub, has a suction inlet for coupling to the pump, and has an internal surface with an equilibrium tube arranged therein with three openings, a first opening that acts as a water flow inlet, a second opening that is open to the atmosphere via a connection hose or other suitable connection device and that is filled with water during normal operation, and a third opening that is a safety orifice coupled to the suction inlet. During normal operation water flows from the first opening, through the equilibrium tube, and out the third opening. During a blockage when water stops flowing through the suction body to the suction inlet and water pressure decreases, water in the equilibrium tube evacuates out the third opening, and air is drawn from the atmosphere through the second opening and out the third opening, causing the pump to cavitate so the blockage may be removed.
