Our current house has septic. Had no idea how they worked. The owners were no help. Called the first phone # in the book. AAA Septic Services. My new best friend. He opened it up to give me a lesson. If you've never seen 1,000 gallons of poop & pee, you haven't lived. He reported it was in fine condition, mostly liquid with limited solids & draining cleanly to the distribution box. Leave it alone. If it's causing any problems, you'll know. That was 12 years ago.

Rules: No wipes, no clogged toilet chemicals, grey water drained to a seperate system (dishwashers/washing machine). He said Rid-X is OK, but not needed if you follow the rules.
