Hi all,
I am building a new home in middle TN and have a question about venting my DWV system. I have a plumber and his work is impeccable, but I am not sure about his plan for the vents. I certainly don't want any more roof penetrations than needed, so..
He has installed 3" vents for all the toilets-2 at one end of the house, and 3 at the other. He intends to neck down the 3" and make it 2" right above the top plate, then manifold all together, and go out the roof at 2". Bear in mind that there are lavs, and showers in these locations as well. Effectively, under his plan, I'll have 2-2" roof penetrations. Is there a fixture count per roof vent...or??..that you all might enlighten me with? Thank you for your time
