Abstract
Air gap assembly for preventing backflow from a waste line to a dishwasher or other appliance connected to the line. The assembly comprises a vertically extending hollow body, an inlet tube extending upwardly within the body, an outlet tube connected to the body, an air vent in the body in proximity to the upper portion of the inlet tube, and a deflector cap mounted on the body above the inlet tube. Water entering the device through the inlet tube is deflected in a downward direction toward the outlet tube without leakage through the air vents, and the air vents prevent syphoning action which might otherwise produce undesired backflow from the waste line to the appliance connected to the inlet tube.
Claims5
In an air gap assembly for preventing backflow from a waste line to an appliance which discharges into the waste line:
- a vertically extending generally cylindrical hollow body, an inlet tube for connection to the discharge outlet of the appliance extending upwardly within the body and communicating with the interior of the body through the upper portion of said tube, and outlet tube communicating with the interior of the body for connection to the waste line, a pair of diametrically opposed air vents in the body in proximity to the upper portion of the inlet tube, a deflector cap mounted on the body above the inlet tube with a depending skirt interposed between the upper portion of the tube and the air vents, said skirt extending downwardly within the body to a level below the air vents, and a pair of hooks projecting outwardly from opposite sides of the deflector cap in locking engagement with the diametrically opposed air vents for securing the deflector cap to the body.
