The valve is open at its lower end and closed at its inner end having a head which seats against the inner end of the body. The lower end of the valve includes an abutment surface for engagement by a drain conduit fitting for axially displacing the valve inwardly to open the valve and permit flow therethrough. A cap may be mounted on the body to enclose the lower end of the valve when the fitting is not in use.
