Abstract:
1. A valve apparatus comprising a water drain valve arranged to be attached to an outer wall of a fluid containing vessel, the outer wall of the fluid containing vessel having a recess formed in a surface thereof providing a recessed surface, and an aperture formed through the recessed surface, the water drain valve including a body arranged to be received in the aperture and a non-circular flange of the body arranged to be received in the recess such that the non-circular configuration of the flange in combination with the recess limits rotation between the water drain valve and the outer wall of the fluid containing vessel, wherein the body has a conduit for providing an outlet from the fluid vessel, and wherein the valve apparatus includes a cap having a circumferential sidewall including an inner surface, a closed end, an open end, a fluid volume space and a fluid transfer aperture for fluid to enter the fluid volume space and the open end being configured to encapsulate a portion of the valve body such that at least a portion of the fluid volume space forms a substantially fluid-tight passageway between the fluid transfer aperture and the conduit, the substantially fluid-tight passageway being defined between the inner surface of the cap and an outer surface of the valve body.
