My sewage ejecter pump used to work every time I flush my toilet now it work second or third time I don T know if it the pump or the float. What do you think?

If you're still pumping my bet's on the float switch setting. However, if the tank emptys with no problems why open it up and reset the float? Good luck, Tom

Agree with Tom. It is actually better to be able to get a few flushes before the pump kicks on. The pump is working, and so is the float if the pump is kicking on and off and no backups in the basement fixtures. Just keep an eye (or ear) on it. Take care.
