Is there a consensus or rule of thumb for minimum sanitary pipe slope for commercial buildings with low flow plumbing fixtures? The urinal is 0.125 gpf, lavs are 0.35 gpm max, and toilets will be either 1.0 or 1.28 gpf.
I read a paper from Sloan Company, but there was no information other than more water and steeper is better. It did not give a minimum slope to use.
The 2015 IPC allows an 8" pipe to slope at 1/16" per ft. If I read the California Plumbing Code correctly, the minimum slope for any pipe size appeared to be 1/8" per ft and I am thinking that perhaps I should not slope less than 1/8" per foot.
Does anyone have any solid information?
Thanks
