Backflow Gauge Certifications

Differential pressure gauges are required to be tested for accuracy when purchased and annually thereafter by most jurisdictions. This service is provided by Bac-Flo Unlimited throughout the year which verifies that gauge accuracy is + / - .2%. If this requirement is met we issue a detailed certification report referring to the gauge’s serial number and the testing company's information. The fee for each gauge certification is $60.00. If your gauge is being shipped, contact us for our secure shipping address and add $20 for the return shipping charge. Note: the gauges sold on this site come with this same certification and is included with the purchase price. Additionally it's the same certification that our students receive at no charge in their continuing education courses. Feel free to contact us for additional information.

Bac-Flo Unlimited: "Don't Settle for Less!"


*Free Gauge Certifications - One free gauge certification and report is available to each enrolled student in a continuing education course.  This service is offered at no charge only at the time of the course. Note: gauge testing is not part of course instruction, though Bac-Flo Unlimited can offer this service due to the advantage of having two instructors on site.

*Free Troubleshooting Assistance - After completing the 40 hr. tester or 24 hr. renewal course, backflow prevention assembly testers can contact one of our instructors for in-field assistance in the troubleshooting and repair of backflow prevention assemblies. In most instances they can help solve your problem over the phone.

*Two Instructors - This is beneficial in the hands-on training for backflow prevention assembly testers. It enables the student the opportunity to have personal one-on-one training with an instructor.

*National ABPA Tester Certification - This certification is useful for testers who plan to test backflow prevention assemblies outside of Texas. The course and training material are the same as for the standard state certification, with the exception of the written exam and final certification coming from the American Backflow Prevention Association. Add $150 to the price of the 40 hr. tester course for this national certification.

*TCEQ Training Credits - Texas Commission on Environmental Quality (TCEQ) training credits are provided with all courses for Backflow Prevention Assembly Testers and for other water licenses when attending the 40 Hr. Tester or 8 Hr. Fundamental Course. CEUs are also provided by the Texas State Board of Plumbing Examiners for credit toward obtaining a Plumbing Inspector's License.

*Separated Practice Stations - Backflow testing stations are spread out and separated in every course with seating. Additionally all four types of assemblies are easily interchangeable by students themselves. The result is a relaxed atmosphere, an optimized learning environment and the opportunity for one-on-one training with an instructor.

*Learn from Experience - Courses are taught by experienced instructors in the areas of enforcement, testing, troubleshooting and repairing backflow prevention assemblies. You will learn first hand the dos and donts. Cross connection control and backflow prevention is our primary focus.
