  • Wet Vent A Flat Vent???????

    I ran into something interesting, I am not sure if it is legal or not, not to sure why it wouldn't be, (it's not the way I would have done) but I wanna ask opinions..............I had a stoppage today, no main line c/o, pulled the toilet, located a 3" closet flange, a 3" 1/4 bend, right off the 1/4 bend, a 3x2 wye rolled at 60 degrees, then another 3" 1/4 bend (all horizontal) into a verticle 3" comby to the main. Off the 3 x 2 wye, a 2" 1/8 bend going verticle up the wall 2' and picks up a santee for the lav, then 2" continues up as the vent penetration. So I guess I would call this wet venting a flat vent??? One thing is for sure, I would have screwed the closet flange down!

    Ia is considered vertical wet vent the wye doesn't go below 45 deg., thereby making it a flat vent, the 45 angle establishes horizontal or vertical.
