That I have seen a mistake like this one in the pic. The angle of the pic is misleading looks like flow travels to the right side but that is just the angle I was laying at not the actual flow. There is a bathroom coming from the left side and a utility room from the right side and the top of the pic is the discharge toward the septic tank where do use suppose the solids from the left side bathroom are going to hang up:shock::shock:
Good catch Charley.
