    Plumbing Vent for Toilet

    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.

    Toilet vent question

    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...

    Toilet distance from new soil stack vent

I would like to plumb the bathroom as pictured below, but wanted to confirm it is OK to have the new soil stack vent as far from the toilet as I have it. The horizontal drain line from the toilet to the stack is roughly 10', and so because...

    Water Closet Venting

    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.

    DWV Layout Feedback

    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...

    Non vented plumbing in Costa Rica

    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...
