What reeflo pump is it? Reeflo's customer service is great if it an wait till tomorrow they can walk you through it and if it is an issue like a seal being broken or a bad bearing (2 more likely mechanical failures) they can get yoh parts for it if its under warranty.

Or if you think it is something that just got sucked up into getting the impeller housing off should be enough. Ill see if i can find the link I usually use to walk me through it to make sure I dont miss a step.
