I have a Tunze return pump and last time I cleaned the impeller I noticed the magnetic piece was starting to corrode. I immediately took it out of service and ordered a new impeller. Unfortunately, without thinking before the new impeller arrived I put the pump back together.

I now can't remove the old impeller. I've tried soaking the pump in vinegar and water but it hasn't helped. Doesn't anyone have advice on how I can remove the old impeller so I can replace it with a new one?

The magnet probably expanded and maybe even cracked, just keep working it from side to side until it starts to move.
