You seem pretty handy so congrats on investigating on your own. What is your household size and how many rooms/bathrooms do you have? You may need to do some investigating with your home inspector or the prior owner about prior disclosures, you may have a valid complaint, esp since it's only been a few months. Check your county records if you can to see what your system looks like. Grizz has lived it and knows his stuff, so be sure to check his links. I had to take a chance and fight with my local septic company and the county for my own septic issues, and it was not fun. Shop around or ask friends for someone you might trust to do an honest eval. It seems unlikely a local municipality would approve a tiny leach field like that in the first place. Good luck to you and trust grizz. -Dave
