Can I get a battery backup pump into an ejector pit? (basement is below street line so need ejection for bsmt fixtures). I already have one on my sump pit which has never been a problem. However about 6 years ago I lost power and the basement ejector pit backud up out the basement floor drain due to the water softener going into backwash mode during the outage (its a Kinetico softener that uses no power).
Have any of the plumbers here ever put a battery backup on an ejector pit (dual pumps)?
I dont expect it to eject solids, just keep the water level down in an emergency.
