Hello all. I'm looking for guidance on the attached plumbing configuration for two bathrooms. I had a discussion with a local inspector (UPC, no relevant amendments) who stated that it wouldn't work but did not elaborate.
908.2.1 My dry vent connection is connected at the bathtub trap arm (dedicated 2-in dry vent at each bathtub) and meets 905.2 and 905.3.
908.2.2 The discharge into the wet vent includes the lavatory and bathtub (3 dfu)- I read this section as total dfu going into the pipe upstream of the trap that is wet-vented (the toilets)
908.2.3 Trap arm length on the toilets seem fine (<10 ft), the vent pipe is below the weir but thats ok because its a toilet.
908.2.4 The toilets (water closet fixture drains) are downstream of other wet-vented fixtures (there are none)
908.2.5 The kitchen and laundry drain into the 4-in pipe downstream. Those fixtures are conventionally vented.
