Hello. I have an ejector pump that will run extensively and while running vibrates to the point that it can be heard throughout the house. Can you offer any ideas as to what might be happening and any solutions to this dilemma?

I think the impeller has gotten hold of something it can eject. This debris is just spinning around inside the house causing the vibration and the longer than normal run time. You will not enjoy getting at the debris so I wish you good luck.
