A black tank sewer flush adapter comprises a tubular body, a boss connector connected to or integrally formed to the tubular body, a flexible sealing washer, and a fastener. The fastener is for forming an attachment with the distal end of the boss connector while the water hose passes longitudinally through at least all the opening of the fastener, the opening of the flexible sealing washer, and the distal end opening of the boss connector. By allowing the water stream emitting end of the water hose to pass through the boss connector and the proximal end of the adapter and into a black tank, the water stream can be applied directly to the interior surfaces of the black tank and a net increase in dislodging adhered sludge from the interior surfaces of the black tank is observed.
