new 2 story plumbing plan - help

[MTTim]

Hello all,
new member that can use all the great help from you guys on Terry's site. I have been reviewing a lot of threads and now I am at a point to ask you all to see if my plan meets UPC code.

Here is a sketch of my plan. rough but got most things I think. I have not listed all my fittings or any measurements but I think I got venting basically right between floors knowing there has to be 42" above floor to get above 6" over flood level. Please feel free to correct anything I have done wrong and ask if my drawing is confusing. Looking forward to your comments.

Thx
Tim

Looks fine to me for the UPC if you want to dry vent every fixture.

Wayne,
thanks for your review. what would be the advantage of wet venting? less piping/fittings/or other? where and how would I do it? I was worried about making a mistake if I tried to simplify or get creative!

Thx

thanks for your review. what would be the advantage of wet venting?

The upside is fewer dry vent takeoffs, so less piping on the dry vent system.

where and how would I do it?

The basic idea is that you can use the dry vented lav drain to wet vent the associated shower, tub, and/or WC. So possibly just have one dry vent takeoff per bathroom group.

BTW, I notice at one point you specify a low heel 90 and at another you specify a 3" san-tee with bushing on top. Those are the same idea and interchangeable. I.e. a low heel 90 with 2" inlet is just another name functionally for a 3x2x3 san-tee.

Cheers, Wayne

I think it looks great ! I may have missed something but you seem totaly on track. Waynes point I think would be save some labor and material, but a particular owner might want to overbuild Including I* might go as far as removing the low heel outlet and just run 3 inch up off the last toilet for a full size vent. btw Will your AHJ require you to up the vent pipe size going through roof for snow or frost in Montana?
Anyway I like your plan Just matter of whether you want to save a little work and material Id run with what you got. we do it all the time in commercial and institutional run over size and bullet proof but its not quite free.

Wayne and Jeff thx for more comments.
I will try to markup my dwg with some wet venting to make sure I get it right.
I thought I would use the low heel 90 on upstairs toilet so it would fit in my 2x10 floor joist cavity that sets above my 2x6 downstairs plumbing wall located between my laundry/mudroom and down bathroom.
Also Jeff I don't know if vent through roof needs uprising due to snow/cold will check into it.

Low heel is fine ..
