908.1 Vertical Wet Venting
JUMP TO FULL CODE CHAPTER
Wet venting is limited to
vertical drainage piping receiving the discharge from the
trap arm of one and two fixture unit fixtures that also serves
as a vent not exceeding four fixtures. Wet-vented fixtures
shall be within the same story; provided, further, that
fixtures with a continuous vent discharging into a wet vent
shall be within the same story as the wet-vented fixtures.
No wet vent shall exceed 6 feet (1829 mm) in developed
length.
The vertical piping between two consecutive
inlet levels shall be considered a wet-vented
section. Each wet-vented section shall be not less than one pipe size exceeding the required minimum waste
pipe size of the upper fixture or shall be one pipe size
exceeding the required minimum pipe size for the sum
of the fixture units served by such wet-vented section,
whichever is larger, but in no case less than 2 inches
(50 mm).
Common vent sizing shall
be the sum of the fixture units served but, in no case,
smaller than the minimum vent pipe size required for a
fixture served, or by Section 904.0.
