<br />vent piping shall permit the admission or

<br />vents are required in two or more branch in-
<br />tervals. The vent stack shall terminate in-
<br />dependently above the roof of the building
<br />or shall be connected with the extension of
<br />the soil or waste stack (stack vent) at least
<br />6 inches above the flood level rim of the
<br />highest fixture. Every building in which
<br />plumbing is installed shall have at least one
<br />main stack which shall run undiminished in
<br />size and as directly as possible from the
<br />building drain through to the open air above
<br />the roof.

<br />used also for any purpose other than weather
<br />protection, the vent extension shall be run at
<br />least 6 feet above the roof. Each vent ter-
<br />minal shall be made watertight with the roof

<br />terminal from a drainage system shall be di-
<br />rectly beneath any door, window or other
<br />ventilating opening of the building or an
<br />adjacent building nor shall any such vent
<br />terminal be within 12 feet horizontally of
<br />-such an opening unless it is at least 3 feet
<br />above the top of such opening. Vent ter-
<br />minals shall not: terminate under the over-
<br />hang of the building: No soil, waste or vent
<br />pipe extension of any new building shall be
<br />run or placed on the outside of a wall but
<br />shall be carried up inside the. building.
<br />(d) Extension through wall. Vent ter-
<br />minals extending through a wall shall be at

<br />all subject to the specific approval of the
<br />Building Official.
<br />(e) Provision against frost closure. Vent
<br />extensions and vent terminals extending
<br />through a roof or wall shall be not less than
<br />the diameter of the vent stack or stack vent
<br />which they serve but in no case less than 4
<br />inches in diameter. A change in diameter,
<br />if required, shall be made at least 1 foot
<br />below the roof construction or, for exten-
<br />sionsthrough awall, at least 1 foot inside the
<br />inner face of the wall.

<br />(a) Slopes, All vent and branch-vent
<br />pipes shall be free from drops or sags and
<br />shall be sloped and connected so as to drip
<br />back to the soil or waste pipe or vent stack
<br />by gravity.
<br />(b) Soil or waste pipe. Where vent pipes
<br />connect to a horizontal soil or waste pipe,
<br />the vent shall be taken off above the center
<br />line of the soil or waste pipe and, wherever
<br />possible,. shall rise vertically, or at an angle
<br />not less than 45° to the horizontal, to a point
<br />at least 6 inches above the flood-level rim of
<br />the fixture it is venting before offsetting
<br />horizontally.. or, before .,connecting ,to, the
<br />branch vent, except as may be otherwise
<br />approved by the Building Official. Side-inlet
<br />closet bends, with center line of side tapping
<br />above the horizontal center line of the bend,
<br />are permitted only incases where the fixture
<br />connected thereto is vented and in no case
<br />shall the inlet be used to vent a bathroom
<br />group without being washed by a fixture.
<br />(c) Connection to vent stack. A connec-
<br />tion between a vent pipe and a vent stack
