Description
2018 International Plumbing Code (IPC)
The 2018 International Plumbing Code sets the minimum regulations for plumbing fixtures, water supply and sanitary drainage systems. Published by the International Code Council, it balances prescriptive and performance related provisions and is used by plumbers, inspectors and engineers to check that installed systems are safe and compliant.
This edition changes several rules from the code before it, covering restroom signage, pipe materials, solar water heating and sewer reuse. The details below are the ones that matter to a buyer comparing editions.
Single-user restroom signage
Under Section 403.1.2, single-user toilet facilities are no longer required to be labeled for a specific sex, which allows gender-neutral signage. This is a change from earlier editions of the code.
Pipe materials and mechanical systems
Schedule 10 steel pipe is now permitted in plumbing systems as a lighter-weight alternative to Schedule 40, which was previously the only option. Solar thermal water heating systems must now conform to the ICC 900/SRCC 300 standard, and the code updates its standards for arc-resistant corrugated stainless steel tubing (CSST).
