Sewer lines should drop 1/4" foot.
2006-08-21 10:06:05 · answer #1 · answered by big_mustache 6 · 1⤊ 0⤋
Per the International Mechanical Code, for 3" and less 1/4" per foot, above 3" is 1/8" per foot but local codes can be more restrictive.

Depending on where you live, check your local codes.
3" and smaller should be 1/4" per foot, 4" and larger should be 1/8" per foot, 8" and larger can be 1/16" per foot or an approved velocity of 2 feet per second. This AR state code.
Hope it helps.

Plumbing Drain Slope

You will need 38 inches of drop. that is 1/4x150=38 inches rounded up. So the tank's attach point 150 feet away would have to be 38 inches LOWER in the ground level that your point in the house to achieve 1/4 inch per foot drop.

the amount of slope depends on the size of the drain pipe..larger the pipe less slope.....on a norm, 4" drain line slopes 1/8" per foot but u can use larger pipe which would change this......

Call your local county inspection office because different areas have different requirements.
