White Paper: Plumbing Codes and Considerations for a Dependable Solution

Codes are critical to the engineering and installation of plumbing systems—existing as a guide for jurisdictions everywhere. Staying educated on relevant codes, changes and updates is an important part of every plumbing professional’s job.

Of particular importance in the plumbing engineer community are the International Plumbing Code (IPC), the Uniform Plumbing Code (UPC), the International Mechanical Code (IMC) and the Uniform Mechanical Code (UMC). The IPC and IMC are developed by the International Code Council (ICC). The UPC and UMC are developed by the International Association of Plumbing and Mechanical Officials (IAPMO). These codes serve as “model” codes, offering recommended regulations that address performance of plumbing and mechanical systems. Local jurisdictions across the world look to these codes and are able to adopt the contained recommendations within their own local codes, modifying them as they see fit. As such, the influence and importance of the model codes is vast. 

As far as plumbing materials are concerned, these model codes make prescriptions for a variety of materials. CPVC, an increasingly prevalent choice for apartments, hotels and many other plumbing applications, has been contained within each of these codes for several decades—a fact that may come as a surprise to those who may have traditionally worked with metallic materials.
