Sizing domestic water pipes

摘要

Design professionals should consider several factors to dictate how water piping is sized for nonresidential buildings, including occupancy type, pressure availability from the source, specialized equipment requirements, and building layout. This article looks at sizing methods outlined in the International Plumbing Code (IPC), as well as explanations to determine when it is necessary to go above and beyond code-minimum requirements. The American Society of Plumbing Engineers (ASPE) and codes based on the Uniform Plumbing Code (UPC) use a similar method.
