Roebic Labs

My septic line and tank are in the good shape. I started using about 12 to 15 years ago. My lines quit clogging up (quarterly use to maintain and Roebic has different products to use depending on particular situation). On a septic system thats over 25 years old - the insides I learned plus the tank need treatments. Best product over time to keep lines and tank in good working shape. (BTW, I have not had my tank pumped out in 12 years)
