Backflow Preventer Testing & Certification

If your building has a backflow preventer on the water line, the water district wants it tested every year and wants the certificate on file. This service sends a certified backflow tester, tests each assembly and files the paperwork, so the notice in your mailbox stops being a scramble.

Testing and certification in one visit

Each assembly is tested to district standards and the result is written up on the certificate your water district accepts. You get the report in your facility portal, and a reminder lands before the next annual due date. Pricing is per assembly, so a building with one device and a campus with ten are both quoted fairly.

A certified tester, not just a plumber

Backflow testing requires a tester certification that is separate from a contractor license. NorTech verifies that credential before a tester can take a job. If an assembly fails, repair is quoted separately and confirmed in writing before any work starts.
