my pump leaks; could it be a bad defuser o ring?
A diffuser o-ring is an internal gasket that would not cause a visible leak on the pump if it failed. A more likely culprit of the leak is either a cracked piece of the housing, bad housing o-ring or shaft seal.

Pros: Very good quality and fit
I did not choose this item, it was suggested by the online chat. Glad they did. Excellent product that fits perfectly. I have a salt system and this one was recommended over the one I asked about. Very happy.

I could figure out why my pool was cloudy when all the chemicals were spot on. That when I noticed this o ring was worn with a slight rip. Replaced it and pool was clear in three hours.....great product shipped and delivered in 4 days....
