Section SPS 382.60 - Pipe hangers and supports The provisions of this section control the types, materials and installation of anchors, hangers and supports for plumbing piping.
(1) MATERIAL. (a)Strength. Hangers, anchors and supports for piping shall be of sufficient strength to support the piping and its contents. Drain piping shall be considered as being full of water. Underground piers for pipe support shall be of concrete, masonry, plastic or pressure treated wood.(b)Compatibility.1. Hangers and straps shall be of a compatible material that will reduce the potential for galvanic action with the piping.2. Hangers and straps may not distort, cut or abrade piping.(2) INSTALLATION. (a) Piping hangers and anchors shall be securely attached to the building's structure at intervals to support the piping and its contents, but not at intervals greater than those specified in Table 382.60, except PVC used for venting may have a maximum horizontal spacing of 5 feet. The connection of drain piping to a fixture or appliance shall be considered a point of support.(b) Hubless pipe installed in the horizontal position shall be supported within 24" on each side of a joint, unless the joint has an alignment retaining shield.(c) Hangers shall not be attached to a building's structure by means of wood plugs.(d) Shower valves and piping from the shower valve to the shower head outlet shall be securely attached to the structure.
