Challenger Pool pump leak

Hi

I replaced parts on my  challenger pool pump (motor-toseal plat, seal, impeller and all o-rings/gasket but I still have a drip at the band clamp where wet meets dry (tighten until squeaking). Any suggestions.  I did not replace the diffuser/spacer

Hi, I would try replacing the diffuser/spacer. Also sometimes if you do not tighten down your impeller hard enough then that will cause leaking so I would doublecheck the impeller.Thank you Patrick
