http://www.homebuildingandrepairs.com... Click on this link if you're interested in more about plumbing, home building and repairs. Watch this video to learn more about sloping drainage pipes. Remember, to always check with your local building department to verify anything you watch on Youtube, including my videos. Building codes can change and often do. Horizontal drainage pipes usually slope a quarter inch per foot unless they're 4 inches or larger, then they might only require an eighth of an inch per foot. Don't forget to keep watching our videos, visit our websites and check out a few of the books I've written.
