Waterway Drain plug EX2

This drain plug screws onto the faceplate of some Waterway pumps: Hi-Flo II, EX2 and Spa Flo II. 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.
