O~.DINANCE NS-21~2 <br />PAGE ~ <br /> <br />(a) Vertical Piping <br /> <br /> Attachment - Vertical piping shall be secured at <br />sufficiently close intervals to keep the piping in alignment <br />and carry the weight of the piping and its contents. Stacks <br />shall be supported at their bases, and as follows: <br /> <br />(1) Cast iron soil pipe - Cast iron soil pipe shall be <br />supported at every story or closer. <br /> <br />(2) Screwed pipe - Screwed pipe (IPS) shall be supported <br />at not less than every other story height. <br /> <br />(3) Copper tubing - Copper tubing shall be supported at <br />each story or at maximum intervals of ten (10) feet (3 <br />m). <br /> <br />(4) Lead pipe - Lead pipe shall be supported at intervals <br />not exceeding four (4) feet (1.2 m). <br /> <br />(5) P.V.C./ABS plastic (D.W.V.) - Vertical piping shall <br />be supported at each story or floor level. Alignment of <br />vertical piping shall be maintained between floors with <br />use of a mid-story guide. <br /> <br />(b) Horizontal Piping <br /> <br />(1) Supports - Horizontal piping shall be supported at <br />sufficiently close intervals to keep it in alignment and <br />prevent sagging. <br /> <br />(2) Cast iron soil pipe - Where joints occur, suspended <br />cast iron soil pipe shall be supported at not more than <br />five (5) foot (1.5 m) intervals; except that pipe <br />exceeding five (5) feet (1.5 m) in length, may be <br />supported at not more than ten (10) foot (3 m) intervals. <br />Supports shall be adequate to maintain alignment and <br />prevent sagging and shall be placed within eighteen (18) <br />inches (.5 m) of the hub or joint. Hubless or <br />compression gasket joints must be supported at least at <br />every other joint except that when the developed length <br />between supports exceeds four (4) feet (1.2 m), they <br />shall be provided at each joint. Supports shall also be <br />provided at each horizontal branch connection. Supports <br />shall be placed on or immediately adjacent to the <br />coupling. Suspended lines shall be suitably braced to <br />prevent horizontal movement. <br /> <br />(3) Screwed pipe - Screwed pipe (IPS), except as provided <br />in Section 1213(f) and Table 12-2, shall be supported at <br />approximately ten (10) foot (3 m) intervals for piping <br />three quarter (3/4) inch (19.05 mm) and smaller in <br /> <br />8 <br /> <br /> <br />
