2021 Uniform Plumbing Code – UPC 1-2021 (IAPMO)
The 2021 Uniform Plumbing Code® (UPC), developed by IAPMO and approved through the ANSI consensus process, establishes minimum requirements for plumbing system design, installation, and inspection. It incorporates the latest safety, efficiency, and performance provisions used across residential, commercial, and industrial projects.
Highlights:
- Adds Appendix N for defining scald risk and Legionella prevention through temperature control
- Updates backflow prevention device standards and installation methods
- Expands temperature-limiting protections for hot water outlets
- Establishes safety requirements for rooftop appliances and raised platforms
- Revises T&P valve discharge piping provisions for clarity and safety
- Introduces requirements for leak detection and monitoring technologies
- Enhances potable water pump installation and performance standards
- Adds DWV system updates for materials, cleanout access, and venting configurations
- Reorganizes medical and fuel gas system chapters for improved usability
Who It’s For:
Plumbing engineers, contractors, inspectors, and code officials enforcing compliant plumbing installations under the 2021 UPC framework.
