The International Association of Plumbing and Mechanical Officials has been protecting the public’s health and safety for more than eighty five years by working in concert with government and industry to implement comprehensive plumbing and mechanical systems around the world.

As a membership-based association, IAPMO is proud to utilize an open consensus process in the development of our flagship Uniform Plumbing Code® and Uniform Mechanical Code®. These codes are established through scientific research, debate, and analysis, strengthening our position at the forefront of the plumbing and mechanical industries.

The IAPMO Group is a complete service organization, providing code development assistance, industry-leading education, plumbing and mechanical product testing and certification, building product evaluation and a manufacturer-preferred quality assurance program. Each component of the IAPMO Group works toward playing an integral part in protecting the health of people everywhere.

With more than 80 years in focused code development and model codes that protect half the world’s population, IAPMO is the natural choice in developing such a document that will equip our industry with the tools to build a better, more sustainable coexistence with the planet.

Committed, Long time leader sustainable model code provisions:

• IAPMO developed the Uniform Solar Energy Code in 1976.
• IAPMO is the first model code agency to partner with the US EPA’s WaterSense program which is providing consumers with a simple way to make product choices that use less water, with no sacrifice to quality or product performance.
• Initial commitment is the pushing forward of a ten percent mandatory reduction in energy usage and water savings through code changes that require sustainable construction practices over the next three years.

The International Association of Plumbing and Mechanical Officials (IAPMO) has a strong cooperative presence in the nation of India and partnered with the Indian Plumbing Association (IPA) to develop a Uniform Plumbing Code for the nation.

The Government of India approved the establishment of IAPMO Plumbing Codes and Standards India Private Limited, to be known as IAPMO-India. IAPMO and the IPA, both members of the World Plumbing Council (WPC), agreed upon a comprehensive plan to work together to establish a model code of plumbing installation and maintenance for all of India, the Uniform Plumbing Code – India. The IPA Code Committee worked with IAPMO staff in creating a document that recognized and utilized proven international concepts, always taking into consideration the proven plumbing practices and customs within India.

IAPMO, the IPA and the Indian Institute of Plumbing (IIP) formed a partnership agreement to provide plumbing training and education throughout India. The agreement identifies four distinct target markets: existing and emerging Engineers, Plumbing Project Managers/Supervisors, basic Plumbing Apprenticeship and task training certification of labor skills. A joint committee of the organizations has been appointed and is already working on the curriculum for each of the four components of the project and development of the training and educational materials.

Built on the reputation of the foremost source of uniform codes and standards in the plumbing and mechanical fields, Uniform Evaluation Service (ES) is the agency of choice for building officials everywhere.

Offering lower prices and faster, more flexible service than other providers, Uniform ES is the smart option for your company’s evaluation needs. Building products, materials, and designs bearing the Uniform ES Mark of Conformity are trusted by contractors, inspectors, officials, and Authorities Having Jurisdiction.

Uniform ES is accredited by the American National Standards Institute (ANSI), giving inspectors and other officials the confidence of knowing that all products displaying the Uniform ES shield have met the most rigorous standards and are in full compliance with applicable codes.

GreenPlumbers® is an innovative training and accreditation program that assists plumbers, inspectors and other building officials in understanding their roles in the environment and public health.

Recently acquired by The IAPMO Group, the goal of GreenPlumbers Training and Accreditation is to train and deploy thousands of residential and commercial “green” plumbers to promote the benefits of water conservation and the reduction of GHG emissions. The focus is on changing consumer and plumbing behavior through the use of energy efficient and water-saving technologies.

GreenPlumbers works with the plumbing industry, building officials, utilities and water agencies to implement the GreenPlumbers program. The training consists of a five-part accreditation in environmental and technical issues including Caring for our Water, Climate Care, Water Efficient Technology, Solar Hot Water and an Inspection Report Service. Since the first classes in late 2007 GreenPlumbers has trained more than 7,000 plumbers in more than 40 states.

GreenPlumbers will hold workshops across the United States, in conjunction with our national training partners, with an ultimate goal of retraining 40,000 plumbers across North America. This has the potential for retrained plumbers to enter hundreds of thousands of properties per day to educate property owners on water conservation and to influence their purchasing decisions.

Implementing a Quality Management System at your business provides a tried and tested framework for a systematic approach to managing your organization’s processes. Management registration standards represent the best tools and practices available to insure customer expectations are consistently met or exceeded.

Likewise, obtaining a Quality Management System certificate from an independent certification body such as IAPMO R&T is the best way to communicate to your clients that your business is operated upon the highest standards.

For over 30 years, IAPMO’s standards-developing efforts have primarily focused on plumbing product standards. This concentration was primarily due to IAPMO members’ expertise from over 50 years of writing and updating the Uniform Plumbing Code.

Recently, IAPMO’s efforts have broadened to include standards for mechanical products. Drawing on their years of experience, many IAPMO members have also contributed to the development of the Uniform Mechanical Code. Mechanical product standards cover heating, ventilation, cooling and refrigeration system products.

IAPMO also publishes standards covering products used in the Recreational Vehicle and Manufactured Housing Industry called IAPMO Trailer Standards.
