my pump leaks; could it be a bad defuser o ring?

A  Answered on 9/25/2015 by InyoPools Product Specialist Matt S.

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.

Can a round 0-ring be used to replace a square one, or will it leak?

A  Answered on 5/19/2019 by InyoPools Product Specialist Lennox H.

Hi. Unfortunately, it will not. The diffuser is designed specifically to use the correct o-ring or gasket.
