An adjustable water supply pipe has a pair of bite nozzles at a bottom end and a wall bracket holding the pipe vertical but allowing the height of the pipe to be adjusted. The bracket has a wall plate with top and bottom plates bent outwardly to define two aligned openings for the pipe. The top plate has a slot which holds the pipe fixed in the upstanding position but with a mouth at one side to release the pipe to an inclined position. The bottom plate is inclined to the horizontal such that the upstanding pipe is jammed against sides of the opening and such that the inclined pipe is free to slide longitudinally. The top plate includes fingers which cooperate with a locking ring on the pipe to hold the pipe upright and the slot is shaped to hold a non-circular portion of the pipe against rotation.
