Designed to ensure the proper installation of plumbing systems, NSPC provides local and state governments, code administrative bodies and the industry with a modern code to protect public health and safety.

To keep the code current and viable and with input from all interested parties, the NSPC Committee — comprised of licensed contractors, engineers, and inspectors — reviews the code annually and updates it on a three-year cycle.
