Is the feed hose above the waterline?

 

[scarf_ace1981]

i know some others who have had problems w/ their ATO. i haven't hooked mine up yet.

More info would be useful... what type of ATO, how is it hooked up, when was it installed, did you try cleaning the float switch, is the pump stopping and creating a siphon?

careful the water isn't being gravity / siphon fed into the sump / tank.
