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

*Free Gauge Certifications - One free gauge certification is available to each enrolled student in a continuing education course.  This service is offered at no charge at the time of attendee's course. Gauge testing is not part of course instruction, though Bac-Flo Unlimited can offer this service due to the advantage of having two instructors for every course.

*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 written exam and tester certification issued by the American Backflow Prevention Association. Add $150 to the price of the 40 hr. tester course for national tester 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.

*Best Hands-on Training - Our backflow assembly testing stations are individually mounted and spread out in courses with available seating for students. Assemblies consist of all four types of and are interchangeable by the students themselves. This results in an optimized learning environment with a relaxed atmosphere 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.
