 Wet Venting a slab on grade
Author: Skipperdan76 (WI)

I need to know how to vent this house as it is slab on grade and I need to know which walls I should use to vent it. There are two bathrooms, a kitchen sink and a washing machine. I also want to plumb for a future bath in the upper room over the garage. The house is 2x4 construction with perimeter continuous insulation. I'd like to keep the vents out of the exterior walls. I understand the tee's and pipe sizes. I was wondering if there was a better route or maybe less messy way of doing it. A licensed Plumber will do the work but I need to know where the pipe is most likely to go so I can create a plan. This is UPC for WI. One last question for the Kitchen sink, Are AAV allowed in WI or do I have to use a loop vent to get the vent over to an interior wall? I need to know where the piping is going so I can make a plan for the concrete pour. Licensed Plumber will do the work.

Thank You for any help, Dan

IF a licensed plumber is going to do the work CALL HIM. Do not try to get him to put the piping in the way YOU WANT IT. If I were he and you gave me the layout, I would tell you to get lost, or raise my prices. And, you install the plumbing BEFORE you pour the concrete.
