Question about Little Giant Plumbing
This morning I came down to the basement to find the pump running and running yet only bubbles and some water were showing in clear discharge tubing. I took off the lid and there was next to no water in tank yet pump still continued to run, so I unplugged it. It is now as if the micro switch has been reversed, the pump works continuously when empty, but if I fill it, the pump stops.

Little Giants are noted for having faulty float switch problems----even the new ones----a major HVAC company I worked for discontinued using them because of this----they remove 1 to 2 years worth of installed pumps and substituted another to because of warranty no heat/ac/flooded floors call backs and returned all of them to the mfg including all of the stock they had---for life of me I can't remember the name of the new ones---when the float failed it would shut down the furnace or ac and usually flood the floor by NOT pumping --- being a service warranty----the pump was replaced not repaired---they probably could of been repaired though with another float switch such as what could be done with yours---that's all I got--good luck

Thank you for posting your question here on Fixya.com.
Replace the check valve that is part if the discharge hose barb. When it fails the water trapped in the vertical section of the tube comes back into the tank and cycles the float on again causing what you describe. The best way to confirm this would be to watch the water level as soon as the pump shuts off and see if it climbs without any other source of water coming into it. If it is not rising then the issue is with the float itself and is not worth fixing; replace the unit in that case.
