Sounds good - less than expected. I hope it goes smoothly. Meanwhile, do you have plumbing? I guess it will be off for part of the job.
Our tank is good, but we need a new drain field. It's 50 years old and water gushed from the field back to the tank when the guy drained the tank to have a look. So effluent can go out of the tank, but very slowly because the drainage in the field is bad. We are okay with it, though it'll be a mess, I think. It looks like the diagnosis is done which I'm happy about.
Ha! We thought we had a clogged pipe and had the pipes cleaned. Nothing found. Probably the septic tank is not draining as fast as it should. So, the cleaning cost us, but at least we know what the problem is not. Tomorrow we get more info from an investigation of the tank. We had it drained within two years, but something is not good. Thought of you. 🙂
