🛡️

Annual testing & certification

Required yearly by your water department. We test the assembly, certify it, and file the paperwork with the city.

🔧

Repairs

If an assembly fails, we rebuild and repair it — usually the same visit — then re-test to confirm it passes.

🚰

New installation

We size, supply, and install new backflow preventers to code.
