Hi folks, I have a leak in the pump housing gasket of a Superpump. A fine stream is shooting out between the pump strainer housing and the seal plate. I have the Seal Change instructions from Hayward. My question is: Do I have to, or should I change out the seal assembly and the diffuser gasket at the same time I replace the pump housing gasket? or should I not worry about these if nothing has gone wrong with them? My pump is about five years old and I use the pool about six months a year. Thanks for any input. Chris
