ABSTRACT A degreasing apparatus which utilizes hot water under pressure from a sink faucet to inject a degreasing solution directly into a blocked U-trap or downstream sewerage system. The degreasing apparatus consists of a small pipe elbow permanently affixed at one end to the output nozzle of a liquid dispenser and provided at the other end with a female hexagonal coupling nut for attaching the apparatus to standard U-traps. To use the apparatus, the input of the liquid dispenser is coupled by a conventional washing hose to the hot water faucet of the blocked sink. The output end of the degreasing apparatus is coupled to the input of the U-trap after the trap is uncoupled from the drain pipe of the sink. After tightening the hexagonal coupling nuts of the U-trap, the degreasing apparatus permits the injection of a degreasing solution from the liquid dispenser container at maximum pressure into a blocked U-trap or downstream sewerage system relying solely on the water pressure pro- vided by the faucet of the sink.
