Proper Pitch On A Sewer Line And House Drain Explained

5/3/2013· The term slope is also frequently used and has the same meaning as pitch. It is generally accepted that 1/4″ per foot of pipe run is the minimum for proper pitch on a sewer line. Larger lines such as 8″ pipe actually require less pitch due to the larger circumference of the pipe. But there are other issues concerning pitch to keep in mind.

Subsurface pipe drainage design and construction

The more permeable the soil, the more rapid the water moves through that soil, and this allows much wider drain pipe spacing. The minimum hydraulic conductivity suitable for tile drains needs to be about 40mm to 60mm per hour. Conductivity rates lower than this requires pipe spacing to be too close, and is therefore uneconomic. See Which subsurface drainage system to use for more information

Horizontal drainage piping shall be run in practical alignment and a uniform slope of not less than 1/4 inch per foot (20.8 mm/m) or 2 percent toward the point of disposal provided that, where it is impractical due to the depth of the street sewer, to the structural features, or to the arrangement of a building or structure to obtain a slope of 1/4 inch per foot (20.8 mm/m) or 2 percent, such

What is the Proper Drain Slope for Your Drain Pipe

7/9/2018· A slope of 1/4 inch per foot is recommended. However, if your pipe is on the longer side, something like 3 inches per foot is better. Confer with your pluer. If your yard’s layout requires your drain pipe to twist and turn, the measurements get more complied. You need to calculate drain slope for each part of the pipe.
