1/4 " per Foot minimum. At least this is what I get out of "Code Check", ISBN # 1-56158-409-6. There is a lot to Plumbing on how pipes are sized, vented and connected. This book is worth getting-I found it on E-bay for less than $10.00.
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.
One quarter inch per foot is standard "slope". This equates to a quarter bubble on a level. If you don't have at least one eighth of an inch "slope", your drain will not work properly and will clog constantly.
1/8 to 1/4 inch drop per foot of length.
With a level
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.
A dishwasher drain pipe actually goes up to just under top of cabinet, then down slightly to join sink drain in next cabinet.
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
A two percent (or 1:50) is considered a good slope for the drainage of lawn areas. The type of soil you have will also affect drainage. With a more sandy soil a flatter slope may be fine.
From $500 up to whatever needed depending on the conditions.
No. If you think about it, upstairs toilets actually drain through the walls and down under the foundation and footings, so you would have a 100% slope there. You can have too little slope, but never too much, since gravity is actually what drains a toilet. Yes you can. Pipes that run vertical are not a problem because friction is not acting on either the solid or the liquid matter. Where a pipe is sloping steeply the water can run away leaving solid matter behind.

2% (1/4" per foot) unless first approved by your plumbing inspector. If there is a lack of grade to allow for the fall you may be allowed to upsize the drain to 6" and run it at 1% (1/8" per foot)
