Hi guys! Does anyone have experience connecting 4X wall mounted toilets to a waste line running behind the wall? Toilets are spaced 3 feet apart, so to keep 1/4" per foot slope, the line will need to be 9 x.25"=2.25" lower at the 4th toilet. Setup is similar to the one shown on a picture, just for 4 toilets.
Thanks!
Thanks!
