Horizontal sink drain in basement
I'm building a half bath in the basement and plan on installing an up flush toilet. In the next room I'm building a kitchenette, complete with a sink. I want to connect the sink drain to the Saniplus system (by Saniflo). I would be running the sink drain along the wall to the area where the Saniplus system is located. My question is, how much fall do I need for the sink drain?
