What is not part of backflow preventer testing & certification
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Any job where labor and materials reach $1,000. A licensed contractor does work at that level, and your tester will say when a repair is headed there.
- Installing, relocating or replacing an assembly on a water line: that is licensed plumbing work done by pros who hold the license.
- Cross-connection surveys and hazard assessments beyond testing, which the water authority or a surveyor performs.
- Irrigation system repair, fire sprinkler work and plumbing repairs unrelated to the assembly.
- A promise that the water authority will accept your paperwork. Acceptance depends on the authority and on the tester it recognizes.
- Building freeze protection, heating of enclosures and replacement of stolen or damaged assemblies.
- In Hillsborough, city of Hillsborough enforces strict permit requirements for structural work. NorTech's scope stays within handyman exemption.
License and permits for backflow preventer testing & certification
Backflow testing is regulated work. Testers hold a backflow certification that is separate from a plumbing license, and pros on NorTech who take this work hold the certification their water authority requires.
Permit and filing rules vary by authority, so ask yours whether routine testing needs one and how the report is submitted. Installing or replacing an assembly commonly needs a permit and a new baseline test, and requirements vary by authority.
Look for the backflow certification on the pro's profile and confirm it is current. Ask whether your water authority keeps a list of accepted testers and whether the pro is on it.

How often to book backflow preventer testing & certification
Testing follows a cycle set by your water authority, so it works best as a standing plan. Each test is booked with your chosen tester, and the plan can be paused or changed whenever you need.
Before you book backflow preventer testing & certification
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Find your authority's notice
Locate the letter or email with the due date, the account number and the accepted forms. It tells your pro exactly what the authority wants, and it helps avoid a rejected report.
List every assembly on the property
Walk the grounds and building and note each device, its size and its location. Irrigation, fire lines and equipment hookups are the usual ones that get missed.
Clear access to each device
Unlock cages and vaults, trim plants around devices and make sure water can be shut off. A blocked assembly cannot be tested and means a return visit.
Warn tenants about the shutoff
Testing interrupts water on that line for a short time. Notify tenants, kitchens and anyone depending on the irrigation or fire line before the visit.
Ask whether your tester is accepted
Some authorities require testers from their own list. Confirm this before booking so the report is accepted the first time.
Book ahead of the deadline
Testers get busy before due dates, and a failed assembly needs time for repair and a retest. Booking early leaves room to fix problems before the authority acts.
