Heads up: There are no amended sections in this chapter.
  1. General. Hangers, anchors and supports shall be of material and strength to support the piping and its contents and maintain its proper alignment. Hangers, anchors and supports shall be securely attached to the building construction at sufficient intervals to support the piping and its contents. Provisions shall be made to allow for expansion, contraction, structural settlement and vibrations. Installation shall be in accordance with manufacturers' directions if more stringent than this Part.
  2. Material. Hangers, anchors and supports shall be of metal or other material strong enough to support the piping when full. Piers may be of concrete, brick or other approved materials.
  1. Attachment. Vertical piping shall be secured at intervals to keep the pipe in alignment and carry the weight of the pipe at its maximum capacity. Stacks shall be supported at their base and, if over two (2) stories in height, shall be supported at each floor by floor clamps. (See Appendix G: Illustrations A and B.)
  2. Cast Iron Soil Pipe. Cast iron soil pipe shall be supported at not less than every story height and at its base. Hubless or compression gasket joint shall be supported at not less than every story height, at its base and at intervals to keep the pipe in alignment and to adequately support the weight of the pipe at its maximum capacity. (See Appendix G: Illustrations A and B.)
  3. Threaded Pipe. Threaded pipe shall be supported at every other story height. Supports shall be of ferrous material.
  4. Copper Tube. Hard drawn copper tube and annealed copper tubing shall be supported at least every story at not more than ten (10) foot intervals. On long lines where there are provisions for expansion and contraction, anchors may be a maximum of four (4) stories apart for cold water risers and drain/waste/vent (DWV) stacks, and two (2) stories apart for hot water risers, provided there are sleeves or similar devices at intermediate floors to restrain lateral movement. Supports shall be of copper material or other material which will not react with the piping material, and which will properly support the pipe.
  5. Lead Pipe. Lead pipe shall be supported at intervals not exceeding four (4) feet. Supports shall be of lead or softer material.
  6. Plastic Pipe. Hangers and straps shall not compress, distort, cut or abrade the piping and shall allow free movement of the pipe. Wire pipe hooks shall not be used to support plastic pipe. Restraining joints and expansion joints shall be installed as required. All vertical piping shall be maintained in straight alignment with supports at each floor level or at intervals of ten (10) feet, whichever is less. Trap arms in excess of three (3) feet shall be supported as close as possible to the trap.
  1. Support. Horizontal piping shall be supported at sufficiently close intervals to keep the piping in alignment and prevent sagging.
  2. Cast Iron Soil Pipe. Where joints occur, suspended cast iron pipe shall be supported within 18 inches of each hub or joint and at not more than 5 foot intervals; however, pipe exceeding 5 feet in length may be supported at not more than 10 foot intervals. Hubless or compression gasket joints must be supported at least at every other joint except that when the developed length between hubless or compression gasket joints exceeds 4 feet, supports shall be provided at each joint. Supports shall be placed on or immediately adjacent to the joint. Suspended pipes shall be braced to prevent horizontal movement.
  3. Threaded Pipe. Threaded pipe 11/2 inches and larger shall be supported at least at 12 foot intervals; smaller pipe (e.g., 11/4 inch pipe) shall be supported at least at 8 foot intervals. Supports shall be of ferrous material.
  4. Copper Tube. Hard drawn copper tube shall be supported at least every 8 feet for one inch and smaller tube, and at 10 foot intervals for larger sizes. Annealed copper tubing shall be supported at least every 8 feet. Supports shall be of copper material or other material of sufficient strength to support the tubing and which will not react with copper piping material.
  5. Lead Pipe. Lead pipe shall be supported for its entire length. Supports in contact with the pipe shall be of lead or softer material.
  6. Plastic Pipe. Hangers and straps shall not compress, distort, cut or abrade the piping and shall allow free movement of the pipe. Wire pipe hooks shall not be used to support plastic pipe. Restraining joints and expansion joints shall be installed as required. All horizontal piping shall be supported at intervals of not more than 4 feet, and at ends of branches, and at changes of direction or elevation. Trap arms in excess of 3 feet shall be supported as close as possible to the trap.
