Tempo:
When 75 mm (3 in.) copper or plastic piping is used, the plumbing stack wall may be made of 38 × 89 mm (2 × 4 in. nominal)
material (Figure 154). Seal around the ceiling penetration to maintain air barrier continuity and prevent air leakage into the attic space
154 Venting for plumbing vent pipes extend through to the open air above the roof rubber boot use 140 mm (6 in.) stud partitions when soil stack continues to another floor washbasin
toilet bathtub soil stack and vent pipe cleanout at basement level
In partitions, holes may be drilled in studs if the remaining portion totals at least 40 mm (11⁄2 in.); otherwise studs must be suitably reinforced.
In load-bearing walls, the remaining portion of the stud must be at least 2⁄3 the depth of the studs; otherwise, studs must be suitably reinforced.
