Features easy-to-understand explanatory text and hundreds of technical diagrams and illustrations. This is the ideal reference for learning the trade, reviewing knowledge or as a general reference to be used with the 2012 Uniform Plumbing Code.
The 2012 Edition of the Uniform Plumbing Code (UPC) represents the most current approaches in the mechanical field. This Fourth Edition developed under the ANSI Consensus process is designated as an American National Standard by the American National Standards Institute (ANSI).
Contributions to the content of this code were made by every segment of the built industry, including such diverse interests as:
- Enforcing authorities
- Research/standards/testing laboratories
- Special experts
The UPC is designed to provide consumers with safe and sanitary plumbing systems while, at the same time, allowing latitude for innovation and new technologies.
Key changes to the 2012 UPC include new provisions for:
- Alternative water sources for non-potable applications
- Rainwater catchment systems
- Plumbing facilities
- Joining methods for water supply and drainage piping
Chapter 4 has been significantly improved through reorganization in the area of plumbing fixtures by expanding their use and application, water consumption and installation requirements. For example, a recommendation for approval as modified for showers that incorporated their application to applicable referenced standards includes water consumption requirements for a maximum flow rate in accordance with ASME A112.18.1/CSA B125.1.
An added provision reduces the risk of scalding by requiring individual and tub-shower control valves to provide such protection based on the flow rate of the shower head be installed at the point of use. The addition of required waste outlet sizing, referencing material and sizing provisions, and the removal of the requirement for a finished dam curb or threshold to aid the aging population, are among changes aimed at providing ease of use for the end user.
