TriStar diffuser is this vent hole normal?

If not can it be epoxied?

Was the impeller rubbing on the diffuser?

Discovered wear ring split digging into diffuser.

Wear ring split. Can i run without the ring until parts arrive. Pump was working fine..plenty of pressure and quiet.

 

[JamesW]

It should work ok without the ring until you can get a new one.

I would replace the diffuser.

Pump works fine without impeller ring but has slight gurgling sound...new diffuser and impeller ring on order.
