A plumbing fitting (Fig. 8 embodiment) has an inlet pipe 821 connectable to a water supply 2 such as a wall elbow, an outlet 822 connectable to an appliance, and a valve 820 between the inlet pipe and the outlet that can be moved to allow or cut off water flow between the inlet pipe and the outlet. No part of the fitting extends beyond the profile of the inlet pipe. In embodiments such as Fig.3 the outlet of the fitting is taken to be the threaded socket 522a into which the outlet pipe 522 is screwed, so the outlet of the fitting itself does not extend beyond the profile of the inlet pipe!
