ABSTRACT:
A recirculating pump assembly in a self contained recirculating sewage system includes a filter surrounding a pump housing positioned in a sewage holding tank. A water rotated filter rinse assembly including a filter rinse member having a plurality of tangential spray holes is rotatably positioned around the housing of the water pump assembly and spaced adjacent the inside surface of the filter. After the sewage holding tank is emptied, rinse water is supplied to the filler rinse assembly. The rinse water in flowing out the spray holes rotates the filter rinse member to clean the filter and the holding tank. The filter rinse assembly includes a water inlet passage with an anti-syphon valve. The pump assembly includes a coupling to drivably connect the pump motor and the pump.
