In order to facilitate the development of an updated National Standard Plumbing Code–Illustrated (NSPC), the IAPMO NSPC Committee is requesting proposed changes to the 2018 NSPC. All proposed changes are due by March 1, 2019. If approved, these changes will appear in the 2021 National Standard Plumbing Code–Illustrated.
All proposed changes must be submitted in electronic form to email@example.com. If a standard is referenced, a copy of that standard must accompany the proposed code change that is submitted to the committee.
The National Standard Plumbing Code uses an annual review process and publishes the complete code every three years.
For a copy of the code change form with instructions or more information on the National Standard Plumbing Code–Illustrated, visit IAPMO’s website.
