I am in MN which follows the 2020 UPC. I am splitting a 10x7 full bath into 2 smaller 5x7 baths (3/4 one side, full other side). To accomplish this the existing fixtures & drains will all have to be moved. There is an existing 1.25" vent which I'll be reusing (upping the size to 2") as well as the main stack which is 3" i'll be reusing. The room underneath the bathroom is an unfinished storage room so I'm ok with dropping pipes a bit lower to accommodate the weird layout
I attached a diagram of the proposed new layout, as well as the proposed plumbing diagram. Reading through the UPC I am most concerned with the vertical venting of the toilet. The code states 6ft is allowed from the flange to the start of the vent. Does that mean where it connects to the main stack, or does it have to get all the way up to past the lavatory above where it's no longer wet vented?
Anything else jump out as being incorrect? Note that some of the horizontal connections are marked as wye, but may become combo tees instead depending on the angle of the trap arms connecting in.
