Re: what is "normal" lateral lines?

Escape,

You need to hydrojet all of your lateral pipes from the distribution box. The microscopic particles leaving your septic tank over the years have clogged up the lateral pipes underground.

I did this myself with a high pressure water pump and a clog hog hose. But there are septic plumbers that will do this for you. Your septic system will give you never ending problems until you hydrojet the laterals. See the videos I've provided in my docs:

The videos in this document are SHOCKING beyond belief.
