Training and Certification 

IAPMO-BPI provides training toward professional certification in backflow prevention. Our courses prepare students for each credential identified in the ASSE/IAPMO/ANSI Series 5000 professional qualification standards:

  • Backflow Prevention Assembly Tester,
  • Backflow Prevention Assembly Repairer,
  • Cross-Connection Control Surveyor,
  • Backflow Prevention Program Specialist/Administrator and
  • Fire Sprinkler System Cross-Connection Control Tester

Each course includes an American Society of Sanitary Engineering certification exam at the conclusion of the training. These ASSE certifications are recognized by model plumbing codes in the United States, including the Uniform Plumbing Code. IAPMO-BPI is dedicated to water system safety through plumbing-code compliance and supports the ASSE certification program. 



*Certification and pre-requisite Information:
Backflow Prevention Assembly Tester Certification Pre-requisite: Five years of industry-related experience
Backflow Prevention Assembly Repairer and Cross-Connection Control Surveyor Certifications: Hold current Tester Certification
The IAPMO training program provides the student with the necessary knowledge and skills to become an ASSE certified backflow preventer tester, repairer, or cross-connection control surveyor.
When completing the application for the tester courses, IAPMO must receive a photocopy of any current certification for re-certification purposes or provide a minimum of 5 years experience in the industry prior to becoming certified as a backflow preventer tester.
Applications must be received by IAPMO two (2) weeks prior to a course start date. This insures that training and certification materials will be available from ASSE for that course.
The certification examination consists of a written examination and a hands-on examination. The exam for an initial tester certification consists of 100 questions. The re-certification exam consists of 25 multiple-choice questions. Presently, the initial certification candidate must demonstrate the field test procedure for a reduced pressure principle assembly, double check valve assembly and a pressure vacuum breaker assembly, without notes or assistance. A re-certification candidate must demonstrate a field test procedure for a reduced pressure principle assembly and a double check valve assembly.
All candidates will know of successful field test exam results at the time of the test. All written examinations are submitted to ASSE for grading, and certification credentials are provided within two to three weeks after the exam. These certification credentials will be mailed from IAPMO. If a certification candidate is not successful, a written notice will be provided from ASSE.

IAPMO can provide training at your location. If your company or organization has a group that needs any of our Backflow Training and or certifications, please contact IAPMO and we can schedule your own backflow prevention class.

Backflow Prevention Institute to Expand Certification Class Offerings
In early 2016, the International Association of Plumbing and Mechanical Officials’ Backflow Prevention Institute will begin offering an expanded program of certification classes in backflow prevention installation, assembly repair, and cross-connection surveying. Several new four- and eight hour training classes for building, plumbing, and mechanical inspectors will also be offered, along with online seminars.

These programs, which are being developed, are in addition to the ASSE cross-connection training IAPMO BPI has been conducting for a number of years. BPI is bridging the gap between the different stakeholders who make up the cross-connection industry by offering certification and training to individuals in the inspection, irrigation, water, and wastewater industries. As an industry leader in cross-connection training, BPI is continuously expanding its programs to new areas across the United States.

IAPMO BPI is looking for volunteers for its new certification committees who will work to develop strong and balanced training requirements, guidelines, and both written and practical examinations for these new certifications.
