What fall should a waste pipe have?
The most important bit of obvious advice ever: soil and waste pipes need to be on a downhill gradient! The “fall” or “drop” should be between 1/40 (1cm down for every 40cm across) and 1/110. Too steep (1/10) then the water runs quicker than the solids so doesn’t wash them away (ugh!).
Can you put a 90 in a sewer line?
You should design your wastewater pipes in a similar manner, for the most part. It’s a bad plumbing practice to have a hard 90-degree bend in a horizontal drain line that’s buried in a slab or otherwise hidden. All drain lines should have a minimum fall of an eighth of an inch per foot of horizontal run.
Should I use solid or perforated drain pipe?
If absorption and drainage are required, perforated pipe should be used. If pipe serves only to move water away from an area (such as downspout run-offs, etc.), non-perforated pipe is best because it will not dissipate water into the surrounding area.
