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.

How much slope do you need for a drain pipe from a new bathroom and what do you do if there isn't enough slope?

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.


Can you have too much slope on a toilet drain line?

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.

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.


How much fall in a toilet drain pipe?

From various sources I gathered that the minimum fall (slope) is 1cm fall over 1m distance. Converted that is 0.125 (1 eighth) inch fall over 1 foot distance.The maximum that should not be exceeded is 1cm fall over 20cm distance. Converted that is 0.25 (1 quarter) inch fall over 4 foot distance.


What should you do if your shower gurgles when the toilet is flushed and the toilet doesn't always work and you also get a drain pipe leak in your basement when too much water is used at the same time?

First thing you should do is call a plumber. Drain lines are not supposed to leak. Your drain line is clogged and needs to be snaked out and the leaking pipe repaired.
