Wet Vent Configuration
Is the attached diagram allowed ( For the toilet and shower marked in blue is that allowed for the wet vent? Toilet is supposed to be most downstream fixture of wet vent.
Very restricted about what I can do here since from the bend of 3” pipe there is 14” until it converts to a 4” wye to other bathroom. All current plumbing is cast iron.
Hoping to cut out a section, fernco new section to cast iron and then connect shower and toilet as in picture.
