Im in suburbs but we go by chicago plumbing code. Im roughing in plumbing for a bsmt bathroom. Is a 3" PVC toilet drain pipe under the concrete slab for a toilet code in Chicago or is 4" required? Or 3" only ok for a max distance? I'm only going about 4' but would like to know if distance determines this.
(BTW I know a 2" drain line is the minimum that can be buried under a slab in Chicago, like for a tub - instead of 1.5". So wondered if a toilet is the same where you have to go with the larger size.)
Thanks All & LOVE the forum!!!
