Many states have severe rules & laws, you can't even work on your own septic any more; you need to replace anything not working with a mound system. So, depending where you live, you can have real problems. A septic liquifies 99% of the stuff going into it in the tank, and the fluid goes out into the lines and soaks away. However most grease (fat) floats to the top and all dirt, lint, and other non-digestable bits settle to the bottom of the tank. You don't ever, ever want the grease or the dirt to build up to where it flows out to the drain lines. This will plug your drain lines real quick, & your septic is done for. There is no way to clean out the drain lines effectively. Now, some folks can live simple lives & have a big tank & their tank doesn't need pumping in 25 years..... Others do 6 loads of laundry a day, lots of grease & stuff down the kitchen sink, and need the tank pumped every 2 years or they will wreck (fill) it. Your drain lines aren't quite right. I'd sure look into pumping the dirt & grease out of the tank, & check if something simple (or major) is wrong with the tank lines & connections. Perhaps your distribution box is messed up, only feeding one line. Or the like. Spending the money on that now can save you a $10,000 mound system sometimes. Waiting & just hope things keep working can compund a simple problem, & plug up your lines. Then you need to start over. --->Paul
