A multi-purpose plumbing tool includes first and second tubular sockets. A first end portion of each of the tubular sockets has four notches therein, extending inward from a first end of the tubular socket and spaced from each other on 90° centers, for receiving complementary parts to be rotated and tightened or loosened by one of the sockets. Preferably, the second end portion of the second tubular socket can be removably mounted on the first end portion of the first tubular socket to rotate with the first tubular socket. The second end portion of the first tubular socket has a means for rotating the first tubular socket to tighten or loosen complementary parts received in the notches of the first tubular socket or received in the notches of the second tubular socket when the second tubular socket is mounted on the first end portion of the first tubular socket.
