Yep got mine from "Piedmont Biofuels" as well. Any clue as to the best cleaner to use to remove the oil residue?

I would go with the higher rated pump just to give me more options.
On another forum someone commented on it not being able to handle solids.
I would think that a pond pump should be able to handle anything that should be in the sump but is this something I should look into?
