toilet venting

Ohio--IPC Existing half bath on slab, planning to add shower and move toilet. I would like to expand my lower bathroom. It is a split-level home with a lower level (bathroom location) and a full basement (mainline location). I have attached a few drawings and would like to make sure the WC...

Hello, I was wondering if this fitting (attached) 3" x 3" x 2" - DWV 90-Degree Hub x Hub Elbow with Lowheel Inlet would work for the 2"inlet to be piped and used for venting outside of the home for a toilet or would it pose an issue? Appreciate the help.

Can I run a vent elbow 3 to 4 inches on top of my sanitary tee to run through my floor joists to the nearest wall to run to the roof due to spacing limitations

I'm installing the plumbing (DIY) in our small cottage in Maine. I'm a bit confused as to what I'm allowed to do with the venting. All plumbing is on the first floor and there is a full basement. The toilet flange is 8' from the vertical vent. My main waste pipe is to be 3" PVC as 4" is just too...

Greetings All, I'm laying out a sub-slab waste system, for a house I'm building in Clackamas County, Oregon, as shown. Would having the toilet vent upstream of the lav/shower drain be acceptable? I'm trying to avoid bringing the vent up the exterior wall.

We have replaced our main sewer line out to the street and are in the process of installing new plumbing to the 1st and 2nd floor bathrooms. The 1st and 2nd floor toilets are directly above one another and previously they both drain into the main vent stack which is directly behind them. The...

We're starting a remodel of a half bath/laundry room, on grade with a concrete slab. I recently pulled the drywall off and carpet up to see what we're working with, and I quickly found that nothing that currently existed in the space had a vent. The toilet appears to have been added at a later...

Greetings. I'm a CA architect living in Costa Rica. I confess I don't know plumbing logistics too well. Neither do the locals. I'm living in a jungle house that's about 15 years old, and all fixtures were installed without roof venting. It's on a septic tank with a leach field. There is a...
