1/4" per ft. is the lowest allowed.
1. Allowed by whom? Not many regulatory authorities specify the minimum slope of a 6" sewer pipe.
2. Why state in inches, typically engineers use a 2.0% or 0.02 / 100' form for the answer.
3. Using Manning's of 0.013 (although most PVC could use a 0.009 or 0.011 n factor, you can achieve the 2 ft/sec typical requirement with a slope of 0.005 or 0.5%, although it was stated to me that 0.0067 or 0.67% is the correct minimun slope to use. I am just trying to find that source which is tough as most authorities do not specify the minimum slope of a 6" pipe.

What is the minimum slope permitted for 2.5 inch underground sewer pipe?
It really depends on your local building code, but 2% should be the minimum so that your pipe will be self-cleaning.
What is the minimum slope permitted for 8 inch underground sewer pipe?
1/16 PER IN PER FT. But the Fixture unit value decreases to only 1440 as opposed to 7300 at 1/2 Pitch.
What is the maximum slope for 4 inch sewer pipe?
1/8th per inch
What is the minimum slope permitted for 4 inch underground sewer pipe?
A slope of 1/4" in 12' is 0.0017 - inadequate for cleansing; it should be at least 0.0084 to produce a reasonable flow velocity of 2 ft/sec. The metric slope I was informed is 18mm in 1000mm Most codes require a 1/4" slope for each 12" of run.
What is the minimum fall for a 4 inch sewer pipe?
1/8" per foot.
What slope to use on sewer drain lines?
One eighth inch drop per foot of run.
How much slope for a 200' sewer run?
For a 200-foot sewer run, a common slope recommendation is 1% to 2% (or 1/8 inch to 1/4 inch per foot). This translates to a total drop of 2 to 4 inches over the entire length. The specific slope may vary based on local codes and the type of sewer system, so it's essential to consult local regulations for precise requirements.
What is the minimum slope required for roof drainage to ensure proper water flow?
The minimum slope required for roof drainage to ensure proper water flow is typically 1/4 inch per foot.
How much slope per foot toilet drain?
All drains slope 1/4 inch per foot, minimum. Too much slope,though, can mean pulling water out of the trap or goose neck on a toilet.
What should the slope be for a shower PVC drain pipe in a home?
One-quarter inch per foot is both the standard practice all around the country and the minimum slope (or grade) allowed by most codes. If maintaining that much slope is a problem, an exception can be requested from the administrative authority.
What is the correct amount of pitch for 6 inch diameter sewer pipe?
.25 per inch per foot
How big is a sewer rod?
A sewer "rod" is normally no larger then 3/8 of an inch diameter BUT a SEWER Cable can be as large as 11\4" even the small sewer rods can have large heads to maintain sewers as large as 36"
