Description

Considering the key requirements of a plumbing system early in a house design can lead to a smoother consenting and building experience, fewer call-backs and happier clients.

When BRANZ arranged inspections of 200 new houses under construction, some of the most common problems involved plumbing. In over a third of the houses, there were framing cut-outs to accommodate pipes that were larger than permitted in NZS 3604:2011 Timber-framed buildings.

Cladding penetrations for pipes that were not properly sealed to the wall underlay – a potential weathertightness risk – were also among the top 10 defects.

Scope

  • Plan well to avoid problems
