The 2006 International Plumbing Code provides comprehensive minimum regulations for plumbing facilities in terms of both performance and prescriptive objectives, and provides for the acceptance of new and innovative products, materials and systems.
The provisions of the 2006 International Plumbing Code apply to the erection, installation, alteration, repairs, relocation, replacement, addition to, use or maintenance of plumbing systems. The code also regulates nonflammable medical gas, inhalation anesthetic, vacuum piping, nonmedical oxygen systems and sanitary and condensate vacuum collection systems. Note that the installation of fuel gas distribution piping and equipment, fuel-gas-fired water heaters and water heater venting systems are regulated by the International Fuel Gas Code.
Important changes to the 2006 International Plumbing Code include:
- Provisions added to require partitions between urinals.
- Outdoor seating now added to occupant loads when determining required number of fixtures.
- New requirements for temperature-limiting devices for bathtubs, whirlpools, multiple showers, bidets, and public hand washing facilities.
- New definitions have been added for Flow Control (vented) and Grease Removal Device, Automatic, to correlate with the revised requirements for grease removal devices found in Chapter 10. The definition for grease trap was removed as grease traps are now called grease interceptors.

- A new section has been added to require backflow protection for the water supply connection to coffee machines and noncarbonated beverage dispensers.

- Section 1003.4 has been revised to require oil separators for all car washing facilities.
