Finding a tester City of Plano accepts

City of Plano publishes its own list of approved testers, and we load it. The 174 companies from it carry a "Utility-Approved Tester" badge on their cards here. See the utility's list.

Before you book, ask the tester:

• Are you registered with City of Plano, and on its current list?
• Will you send the test report to the utility for me, and how?
• When is my report due? The date is on your notice; the tester needs time to test, repair if needed and file.

✓ TX Certified Backflow Tester Verified

A state roster lists at least one certified tester at this business, with a current certificate. The state sets the exam and renewal.

✓ TX Utility-Approved Tester Verified On the city list

The company is on a water utility's own approved list (the second badge names the list). That is the utility's approval, not a state license, and it counts for that utility.
