Welcome to Napa Valley Backflow Testing & Repair

Napa Valley Fire Information

napa fire icon

The Napa Fire has been a terrible tragedy and our thoughts are with all of those affected. During the week of 10-8-2017 through 10-14-2017 we were prepared to evacuate due to our close proximity to the Partrick Fire. During that week we did not have our office set up and were unable to field many calls or attend scheduled appointments. At this point we are working in a triage mode, taking care of customers who need urgent attention. We have communicated with the city water department to address late tests and they are working with us as we try to get back on track.

Quick Backflow FAQ's

What exactly is backflow anyway?

Backflow is the undesirable reversal of water in a customers water system back into the city water supply. Once the water passes through your meter, the city doesn't want it back.

What's a backflow preventer?

A backflow preventer is a mechanical device, containing check valves that close when the pressure in the city water supply drops, thus preventing the reversal of water.

Why do I need an annual backflow test?

The state of California, per Title 17, requires an annual test of all backflow preventers by an A.W.W.A certified backflow tester. Any structure built after 1987 must have a backflow preventer.
