This link is the best video, by far, I have seen for homeowner self inspection. Just in case you are one of those that want to share in the joy in septic work. If you have 25 minutes, please watch this video. If you don’t wish to participate in your self inspection, at least you will see what we are looking at when inspecting your system.
Now this is filmed for those needing explanations at nearly every step. But this includes Gravity, Pressure Distrubution, Sand Filters, and Sand Mounds. This video does not include Aerobic units or Proprietary Septic devices.
