Plumbing Code Research

With a focus on improving consistency and ensuring contemporary practice in the application of NCC Volume Three, the ABCB has an ongoing project to conduct research to contribute to the future development of the PCA. Examples of research undertaken under this project include the following.

Lead in Plumbing Products and Materials

This research seeks to identify the potential for plumbing products and materials to contribute to the presence of lead in drinking water and to identify international practices through a national and international literature review and consultation with interested parties.

Fixture Unit Ratings

The focus of this research is investigating an alternative means of sanitary plumbing and drainage sizing, incorporating modern materials, alternate pipe grades and revised probable simultaneous fixture usage. This approach has the potential to provide the greatest value to practitioners while addressing a large number of sanitary plumbing issues outlined in previous research undertaken on this subject.
