    Hello,

    Simply put, I hired a plumber that failed me. I didn't know this until I found this forum and started learning about plumbing. I am thankful that there are people here that are willing to help, because at this point, I really need help.

    The house is on a monolithic slab. The framing is complete and we are in the "top out" of the plumbing stage. I realized that vents are needed and that vents were not put in place for the shower, bath and toilets. I know, this is obvious to people involved in construction, but this is my first house and I've never been through this process.

    Diagram of the drain plumbing (top down). I know that wet vents can be used for some of this, but I need to know how I should move forward. I assume I'll be cutting the slab open to fix this. Any advice regarding how I can resolve this will really help.

    EDIT: Updated diagram

    Sorry to bump, but I had a plumber come out but he has never heard of wet venting.

    I have highlighted two sections below. Will these adequately wet vent the toilets?

    Thanks

    Wet venting is done with bathroom fixtures on the same floor.
    In your case, the kitchen sink, dishwasher and the clothes washer can't be part of that.

    In the drawings below used with the UPC code on the West Coast, the toilets are downstream of the tubs, shower and lavs.

    Your code may be the drawing below.
