Such vent stack shall terminate independently in the open air outside the build- ing or it may be connected with the stack vent as permitted by Para- graph (a) of this section. A vent stack or main vent shall connect with the soil or waste stack served either through, at, or below, the lowest horizontal waste branch or with the building drain; provided that this will not be required in buildings of less than three stories in height, and that such connection shall not be of smaller size than the so connected vent .

Flashing sleeves shall be not less than 6 inches long and counter-flashings shall be turned down at least one inch into top pipe. -53- (c) Vent terminals shall not extend through the side wall of a build- ing except where a vent is added within an existing building and where it would otherwise be necessary to extend it through more than two existing stories of the building. In such case the vent may be extend- ed through a side wall to outdoors and shall terminate at least 15 feet, measured horizontally, from an adjacent building, and shall be turned downward and shall be screened. Article 5: Distance of Traps From Vents Each vent protecting a fixture trap shall be located so that the developed length of the respective drain from the trap overflow to the vent is in no case more than three feet except for water closets, pedes- tal urinals, trap standard service sinks, and other fixtures which de- pend on siphon action for the proper functioning; of the fixture. Each vent protecting a fixture trap shall be located so that the total fall in the fixture drain from the trap overflow to the vent is not more than one pipe diameter. No vent shall be installed closer than two pipe diameters to the trap overflow. :article E: Dual Vent An individual vent, or a stack vent, installed vertically may be used as a dual vent, when both of the corresponding fixture drains con- nect to the same vertical drain or stack at the same level and when the developed length of each of the two fixture drains is within the limits established herein. Under such conditions, no additional vents for the traps are required. Vent size must comply with vent table.

(b) Non-potable water may be used for flushing wc,ter closets and urinals and other purposes not requiring potable water, provided that such water shall not be accessible for drinking purposes. All piping conveying non-potable water shall be ade- ' quateiy and durably indentified by a distinctly colored paint so that it is readily distinguished from piping carrying potable water. 82 Article 2: Protection of Potable Water Supply (a) Potable and non-potable water supplies shall w be distributed through systems entirely indepen- dent of each other, and any cross-connection be- tween such supplies is prohibited. Further, no con- nections shall be made between pipes containing city water and any other pipes whether or not w� such pipes contain water considered potable. (b) Every fixture supply pipe shall be protected from backflow by having all outlets from which potable water flows spaced a sufficient distance above the flood level rim of the receptacle into which the water flows to provide a "minimum air ■11 gap", except that where it is not possible to provide a backflow, preventer, installed beyond the manual control valve. In special instances where it is not possible to provide either the minimum air gap or a suitable backflow preventer in connections to cooling jackets, condensers, or other industrial or special appliances the Chief Plumbing Inspector shall require a means of protection which is practic- able and successful. (c) Water service and water distribution pipes laid underground shall not be closer to sanitary drains r, and sewers than five (5) feet, where possible, and when laid in approximate alignment with each r other, the water pipes shall be laid at an elevation above all sanitary drains and sewers.
