I am installing a sewage ejector pit and pump in basement, hole is dug and I piped the inlet pvc for the toilet and sink. I did not have time to backfill or concrete.
The next morning I woke up to find after a night of rain the basin floating in groundwater. The septic tank is right next to my sump pump.
If I backfill and concrete the sewage basin and pump in, will the excessive ground water be a problem later?
