I am moving some shower/toilet/vent lines under my basement slab to suit the new bathroom fixture locations. I want to make sure things are all good before closing it back up.
I have run the new ABS lines (2" for shower and wet vent) and in order to achieve the proper slope (1/4" per foot) I need to push the trap arms down a bit to avoid having too much slope. Is this sort of thing ok? or is it bad to have any stress on the ABS connections?
My understanding based on NPC of Canada is trap arms must not have more fall than the ID of the pipe, other than that, "nominally horizontal" drain lines is anything between horizontal and 45 degrees and should be ok. If this is the case, my current setup with more than 1/4" per foot slope should be fine.
Any thoughts? Thanks!
