Gauge Care™, quality calibration and certification for your backflow gauge test kit.  

Ship us your gauge for its annual certification (and repair if needed), and we'll ship it back fully certified usually within 2-3 business days. Or, contact us for weekly certification times in Boerne, TX.

Ship your gauge to our secure shipping address using any delivery method:

Bac-Flo Unlimited, Inc.

215 West Bandera Road

Suite 114, Box 455

Boerne, TX 78006 

- Include with gauge the testing company's name, address, and phone number, along with the physical return shipping address

- For payment include check or money order for $100 per gauge ($75 certification fee and $25 for return shipping), or  click here to pay online.

The usual turnaround time is 2-3 business days for getting your gauge shipped back to you. Please note a delay in return shipping could occur without payment or the required information mentioned above. For maximum shipping protection, most ship their gauge in its hard sided case placed in a cardboard box. Removing heavy objects such as tools and brass fittings can reduce shipping costs. 

Upon receiving your gauge, we'll inspect all moving parts, pressure test different areas of gauge, verify and record accuracy points, and fully certify your differential pressure gauge with an updated certification report valid for a full year. If there are questions or concerns in regard to the gauge needing additional attention such as calibration or repair, you'll be immediately contacted to discuss.  

Our gauge testing and certification department is operated by Troy Baird. He has over 20 years experience in testing, certifying, and if necessary ensuring a quality, factory authorized repair of your gauge. If there are any questions or concerns after receiving your shipment Troy will be personally contacting you.  

Differential pressure gauges are required to be tested for accuracy when purchased and annually thereafter by most jurisdictions. This service verifies gauge accuracy to plus or minus .2 psid in accordance with NIST national standards. Upon instrument verification a detailed certification report is completed in reference to the gauge serial number and testing company, and provided to you. For additional information about getting your differential pressure gauge certified, feel free to contact us by phone or email.

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.

*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 StationsBackflow 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.
