That annual letter from your water district isn't optional: if your property has a backflow preventer — most commercial buildings, fire lines, and many irrigation systems do — it must be tested by a certified tester every year. Gallegos Plumbing's certified backflow testers have handled testing, repair, and installation across Ventura County since 1996.
What a Backflow Preventer Does
It's a one-way valve where your property meets the public water supply. If pressure ever drops in the city main, water can siphon backward — pulling irrigation runoff, fire-line water, or process water into the drinking supply. The preventer stops that, and the annual test proves its internal checks still hold.
Testing, Repair & Installation
We test with calibrated gauge equipment, and when a device fails — worn check valves and relief valves are the usual culprits — we repair or rebuild it on the spot where possible, then retest. Need a new device for an irrigation tie-in, fire line, or commercial connection? We install the correct assembly type for the hazard level and get it certified.
We Handle the Paperwork
Test results have to reach your water district by their deadline, not just sit in a drawer. We file the certification directly with your district — Ventura Water, Casitas, Cal Water, and the rest — so the compliance loop actually closes.
Upfront, Honest Pricing
You approve a flat, upfront quote before any work starts — testing, repairs, and filing included, no surprise line items.
