Abstract: A wrench for engaging a faucet mounting nut, the wrench including an elongated tubular pipe which has slots at one end. A nut engaging socket, having radially projecting studs, is adapted for reversible insertion into the pipe opening, with the socket studs engaging the slots in the pipe. A variety of socket inserts, for engagement of a variety of nut sizes and shapes, is provided. Openings in the pipe, at the end opposite the socket engaging end, provide a means for a rod to be inserted into the pipe to facilitate pipe rotation. The elongated pipe, since it is hollow, can slide over a water supply line during mounting nut removal, thereby eliminating the requirement of first detaching the supply line.
