				the case of an offset in a soil or waste stack below the lowest horizontal
				branch, no change in diameter of the stack because of the offset shall be
				required if it is made at an angle of not greater than 45° (0.785 rad) from the

				shall be sized as follows:
1. The portion of
				the stack above the offset shall be sized as for a regular stack based on the
				total number of fixture units above the offset;
2. The offset shall be sized as for a
				building drain (See Column 5 in Table 725.A.1 of this code);
3. The portion of the stack below the offset

				code); and,
4. A relief vent for
				the offset shall be installed as provided in Chapter 9 of this code and in no
				case shall a horizontal branch connect within the offset or within 2 feet (610
				mm) above or below the offset.

				by the stack.
1. Note: The
				requirement/allowance under §729. A of this code is only applicable if the
				requirement of §905. C.1 of this code has been satisfied elsewhere on the

				of such bars, soda fountains and counters make it impossible to do so. When
				these conditions exist, traps which are roughed in above the floor shall be

				drainboard height and then returning it downward and connecting it to the
				horizontal sink drain immediately downstream from the vertical fixture drain.
				The return vent shall be connected to the horizontal branch through a
				wye-branch fitting and shall, in addition, be provided with a foot vent taken
				off the vertical fixture vent by means of a wye-branch immediately below the
				floor and extending to the nearest partition and then through the roof to the
				open air or may be connected to other vents at a point not less than 6 inches
				(152 mm) above the flood-level rim of the fixtures served. Vent pipes installed
				less than 6 inches above the flood-level rim of the sink shall be installed
				with approved drainage fittings in accordance with §903. E.1 of this code and a
				minimum slope of 1/4 inch per foot back to the drain shall be maintained. The
				return bend used under the drainboard shall be a 45-degree, a 90-degree and a
				45-degree elbow in the order named. Pipe sizing shall be as elsewhere in this
				code. The island sink drain, upstream of the returned vent, shall serve no
				other fixtures. An accessible cleanout shall be installed on the vertical vent
				pipe under the drainboard and another cleanout should be installed in the
				vertical portion of the foot vent. (The cleanout recommended on the vertical
				portion of the foot vent shall be located at least 6 inches above the flood
				level rim of the sink but not more than 4 feet above the finish floor.
				Preferably, the vertical portion of the foot vent and its recommended cleanout
				shall be located on an outside wall with the cleanout accessible outside or, if
				this is not possible, behind a refrigerator, for example, such that the
				cleanout access is not aesthetically objectionable to the occupants.) For food
				service establishments, drainage shall be in accordance with §807. A of this

A. A
				branch soil or waste pipe of uniform diameter throughout its length, to which
				are connected in battery a maximum of eight floor-level fixtures [floor outlet
				water closets, back outlet water closets (provided they connect horizontally
				into the battery vented section), floor drains, bathtubs, and showers] and
				which do not exceed 50 percent of the fixture units allowed by column two of
				Table 725.A.2 of this code, may be vented by a circuit or loop vent system
				connected downstream of the most upstream fixture drain (between the two
				uppermost fixture drains). In addition, battery vented branches on the top
				floor of a building and serving three or more fixtures shall be provided with a
				relief vent connected immediately downstream of the first downstream fixture
				connection of the battery vented section. When a battery vented branch is
				installed below the uppermost floor of the building, regardless of the number
				of fixtures served, it shall be provided with a relief vent connected
				immediately downstream of the first downstream fixture connection of the
				battery vented section. When lavatories or similar fixtures having a fixture
				unit rating of four or less and a maximum 2-inch fixture drain discharge from
				above such branches, each vertical branch shall be provided with a continuous
				vent. Such fixtures shall be located on the same floor as the battery vented
				group and the waste from such fixtures is required to enter the battery vented
				section from the horizontal. Fixtures having fixture unit ratings greater than
				four shall not discharge into such branch from above unless all fixtures in the
				battery group are individually vented. Fixtures from an upper floor or from an
				adjoining or other room(s) or space(s) (other than back-to-back installations,
				for example, back-to-back to bathrooms) shall not discharge into a battery
				vented branch. Floor level fixtures, including but not limited to floor drains,
				discharging downstream from a water closet shall be individually vented (see
				§925. C.5 of this code). Each fixture drain/trap which is connected to a
				battery vented soil or waste pipe branch shall conform with the distance of
				trap from vent requirements in Table 913.A of this code. The developed length
				distance from the weir of the trap or the flange of the water closet to the
				battery vented soil or waste pipe branch shall be used to determine compliance
				with Table 913.A of this code.
1. Exception.
				The relief vent, connected immediately downstream of the first downstream
				fixture connection of the battery vented section, may be omitted on a top floor
				installation of a battery vented section provided a stack vent or vent stack is
				located downstream of the first downstream horizontal fixture
				connection.
