My little giant pump is not pumping - Little Giant Submersible Fountain Pump

SOURCE: sump pump

The big cylindrical thing at the end of the wire hanging is the switch. I believe it is a mercury switch. Try hitting this a little and see if it stops. Sometimes they get stuck. If this doesn't help, then replace that piece. Hope this helps.

SOURCE: I want to replace an impeller for a Little Giant submersible pump

This is a plastic impeller on a brass hub. If the impeller is loose it is probally cracked or overheated and melted, ether way you will have to break the impeller off of the hub then you will need to break hub loose from shaft. You can do this by putting pump in a vise and putting a pair of vice grips on hub and giveing them a sharp hit in a counter clockwise direction. you will need to replace the seal and impeller and should check to be sure than you can get these parts before you start.
