Waterway 3/8" Quarter slot drain plug

This drain plug screws onto the faceplate of some Waterway pumps: E-Series, Executive 48 et 56 Frame, Viper, Hi-Flo. If you are replacing this plug, you should probably replace its o-ring at the same time.

Sometimes this plug is replaced by a small adapter to which a thin pipe is attached. This pipe helps to evacuate air from the pump while the spa is filling, so that it primes more easily.
