About This Book
The 2024 International Plumbing Code (IPC), published by the International Code Council (ICC), establishes minimum requirements for the design, installation, and maintenance of plumbing systems.
Key Purposes & Scope - Public Health and Safety: Regulates safe drinking water supply and sanitary waste disposal. - Innovation: Permits new, resilient plumbing products, materials, and sustainable technologies. - Accessibility: Incorporates requirements from the ICC A117.1 Accessibility Standard. - Application: Serves as the baseline code adopted by state, county, and city governments across the U.S.
Major Updates in the 2024 Edition - Expansive Soils: Added structural support and suspension requirements for buried piping beneath buildings in expansive soil zones. - Water Efficiency: Capped showerhead flow at 2.0 gallons per minute (gpm) to align with high-efficiency standards. - Testing & Materials: Introduced vacuum testing as an option for drain-waste-vent (DWV) piping and added new standards for chemical waste piping and solvent-cemented plastic joints. - Tracing & Safety: Required tracer wire for buried plastic sewer piping and mandated ASTM E84 or UL 723 flame-spread testing for plastic gas-fired water heater pans.
