The yellow lining that mates with the impeller on my diffuser is worn and there is a bit of a wobble between the 2 components.
Other than that both parts are in good condition, the lining appears to be bonded in so I am assuming the diffuser needs to be replaced. Am I correct?
Thank you

Good afternoon Charles, That piece in yours should be copper or brass. It is normal for those to wear over time. Yes, you would need to replace the diffuser as this is all one piece.
