After joining the International Association of Plumbing and Mechanical Officials (IAPMO) in 2015 from the Water Quality Association (WQA), I began studying the U.S. and international plumbing codes in greater detail.
Having worked in the water treatment industry since 1997, I was familiar with the model plumbing codes and state plumbing codes, but since there were very few requirements for water treatment equipment, it was never a significant regulatory focus for the WQA or its members. The model plumbing codes are updated every three years and with each three-year cycle, water quality continues to become a bigger focus for consumer health and safety in homes and businesses.
