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.
