“I’m not a plumber by trade (obviously). Trying to DIY my bath rough in before concrete slab. Would this venting correct? Lav on the left. Shower in the corner. Toilet on the right. Toilet is furthest down stream.”
“Few things: 1. You need a WYE fitting where the drain connects to the vent, to direct discharge downstream 2. The back vent should be rolled up above centreline 3. Try to reduce the number of turns in general. 90° fittings on flat are generally not ideal [re: Please help!]”
Several posts discuss unconventional plumbing vent setups, including those requiring specific heights above fixtures and instances where city codes are seemingly ignored. One post mentions an ejector pump failure leading to basement flooding, while another highlights a code violation related to vent caps.

“I am looking to start renovating my bathroom fully. This floor vent is the weirdest setup I have ever seen. The wall that it is on is an outside wall, so I don’t know if it’s bad practice/possible to run the vent up flush onto the wall or move it to the floor since it’s a bathroom. The vent is both heating and cooling. I plan to rip the floors up eventually. submitted by /u/lilballsack [link] [comments]”
