Description
2021 Uniform Plumbing Code with Tabs
The 2021 Uniform Plumbing Code, published by IAPMO, is the American National Standard for installing and inspecting plumbing systems. It is the mandatory reference for plumbers, engineers and code officials ensuring compliance on residential and commercial projects.
This edition introduces the Water Demand Calculator in Appendix M, a physics-based method for sizing water pipes that can reduce construction costs and improve water quality by preventing stagnation. It also updates medical gas systems, Legionella safeguards and venting standards.
A new way to size water pipes
The Water Demand Calculator replaces older rule-of-thumb sizing with a statistically based method, aimed at cutting material costs while keeping water moving through the system rather than sitting still.
Health and safety updates
Medical gas systems are aligned with NFPA 99, and a new Appendix N adds safeguards against Legionella pneumophila tied to water temperature and stagnation. Circuit venting and storm drainage standards are also revised, and fuel gas provisions are correlated with NFPA 54.
