House septic tie in?
I've been building a house for about 8 months and I'm about ready to tie the sewer into the existing septic system. About 5 years ago I built a shop with bathroom in it, with plans to build the house so the septic is was permitted and installed with the shop.
I attached the pic to show the setup, now the question is how is the best way to tie it in? I could put a new hole in the first tank, or tie it into the existing line. If it's tied into the existing line should it make a U turn so it shoots toward the tank into the old line?
