Abstract: A mechanical tool for facilitating coupling and decoupling of home fittings and caps to a plumbing outlet, such as septic drain outlet on a recreational vehicle is disclosed. The tool includes a handle and two opposed branches extending from one end thereof. The free end of each branch has a slot therein sized to engageably receive one of the two diametrically opposed outwardly projecting lugs existing on a conventional drain hose fitting or drain cap. The branches are roughly spaced such that when in use the slotted free ends of the branches are capable of being adjusted to engagably receive the lugs. An adjustable biasing member susposed between the branches and a position so its not to interfere with the operation of the tool when used to manipulate the fitting or cap. The biasing member allows the tool to be appropriately tensioned such that the branches securely engage the fitting or cap when in use.
