- The IPC is the predominant plumbing code that is used throughout the construction industry and is currently adopted in 36 states, the District of Columbia and Puerto Rico.
- The IPC code provisions are the foundation for the plumbing code requirements in the International Residential Code (IRC). The IRC is a comprehensive, stand-alone residential code that brings together building, mechanical, fuel gas, energy, electrical, and plumbing provisions for one- and two-family residences.
- The IPC is coordinated and correlated with all I-Codes providing uniformity and consistency which reduces both construction costs and issues with design.
- The IPC provides greater design flexibility for builders, especially with the introduction of siphonic roof drainage technology providing savings for builders through reduced pipe diameters, less below grade drainage and reduced trenching requirements.
- The IPC provides environmental benefits including routing to retention and reclamation systems.
- The IPC also allows sidewall vent terminations as an alternative to roof penetrations resulting in cost savings.
