A water valve includes an outlet pipe 10 which defines an inner space 24 containing a reference plane 26. A first extension 20 closes the inner space on one side of the reference plane and a second extension 22 closes the inner space on the opposite side of the reference plane. The outlet pipe of the water valve is arranged to be orientated such that the reference plane is substantially horizontal and one side is above the opposite side. |
