I've been using a Laguna Maxflow 2000 pump as the return pump from my sump. It used to be pretty much silent, but over the last month or so has gotten quite noisy (buzzing/vibration sound). I've already taken it apart to clean it but no success.
I see that Laguna sells replacement impellers. Has anyone tried this?
