Description

Guidance about the function of pressure relief valves in plumbing and drainage systems, including discussion of the requirements in Acceptable Solution G12/AS1.

The guidance was released after MBIE received several enquiries about drain lines from pressure relief and temperature and pressure relief valves discharging to a PVC-U plumbing and drainage system. In some cases, the PVC-U pipes and stacks melted causing a failure of the plumbing system and extensive damage.
