Three inch pipes are used to handle most residential toilets. 1.5 inch lines are used to handle waste from kitchen, bathroom and powder room sinks. 2 inch drain lines are common pipes for laundry drains. Clogs can develop easily on horizontal runs of pipe. Friction causes the water within the pipe to slow down. To achieve good water flow, try to install horizontal drain pipes so they have a minimum of 1/4 inch per foot slope. 3/8 of an inch per foot is actually better.
So, you've finally decided to put that toilet in the basement? And the drain pipes are only three feet above the floor? My friend, in plumbing, 3 feet is as good as 8 feet when it comes to toilet and sink drains. Some things may flow uphill, but waste water isn't one of them! You have three options available (not counting chemical and/or composting-type toilets)... one not too good, one good, one really good.
