About

Overview of the IPC

The International Plumbing Code (IPC) is a proven, comprehensive model plumbing code that works seamlessly with ICC's family of building codes. It sets minimum regulations for plumbing systems and components to protect life, health and safety of building occupants and the public. The IPC is available for adoption by jurisdictions ranging from states to towns, and is currently adopted on the state or local level in 35 states in the U.S, the District of Columbia, Guam, and Puerto Rico.

The IPC is built on the proven legacy of the BOCA National Plumbing Code, SBCCI Standard Plumbing Code, and ICBO Plumbing Code.

The IPC sets minimum regulations for plumbing systems using both prescriptive and performance-related provisions covering topics such as:

  • Backflow prevention
  • Fixtures & fittings
  • Water supply and distribution piping
  • Water heaters
  • Sanitary drainage and venting
  • Traps, grease interceptors & separators
  • Storm drainage
  • Nonpotable water systems (rainwater, gray water, reclaimed water)

Today's IPC is known for:

  • Safety – It has a proven track record providing safe and sanitary plumbing installations.
  • Ease of Use – The IPC uses the same easy-to-use format provided in all I-Codes
  • Embrace of New Technology - The IPC and its predecessors have a tradition of innovation while protecting the health and safety of the public.
  • Correlation – The IPC is specifically correlated to work with ICC's family of codes.
  • Open and Honest Code Development Process - The IPC is revised on a three year cycle through ICC's highly-respected consensus code development process that draws upon the expertise of hundreds of plumbing, building and safety experts from across North America.
