Yes, it is a Sat night and of COURSE that is when the septic tank starts beeping. husband found out how to flip switches from the septic tank guy before he moved, but that is about all we know. So husband made it happy for tonight. From reading the manual I found online I can say with certainty that the person who was supposed to maintain it quit with several years left on the contract that was prepaid. No one around here who deals with septic tanks does this brand. I did find someone who will pump it. I have to call them Monday. We have no smells. I just don't want to ruin the pump. I have said no laundry and no showers more than 10 minutes. Not sure what else to do. Always something else I guess. Sigh. Anyone have any other info on septic tanks?
