Maximum recommended slope for a sewer line?
Minimum slopes are required by code for drain pipes depending on the size but not a maximum. Sewer lines however can have problems with steep slopes causing solids to be left behind during a flush.
I understand that any slope over 45 degrees is safe to use but what would be the maximum slope you can safely use without having this problem? Especially if your using cast iron pipe in an office building in lieu of smooth wall PVC.
The IPC doesn't address this issue. What do you all think? Thank you very much
