Picking the right device
Before anything gets installed, we figure out what your water district will accept for your connection. The hazard level decides the device type. High-hazard uses like clinics, car washes and chemical feeds usually need an RP assembly. Lower-hazard lines may use a double check. Irrigation that only faces backsiphonage can often use a PVB or SVB.
Next comes size. The device has to pass the water you use without dropping pressure too much. Most Corona homes need 3/4-inch or 1-inch devices, while commercial and fire services start around 2 inches.
Getting both right the first time avoids paying for a second install when the district rejects the first.
Built for easy testing and repair
A backflow device isn't a one-time install. It'll be tested every year for as long as it's in place, and repaired from time to time. We install with that in mind.
RPs go above ground with room for the relief valve to drain. Vacuum breakers sit higher than every outlet they protect. Every device gets enough clearance for test hoses, shutoff valves and check covers.
Where theft or freezing is a risk, we'll suggest a locking cage or insulated cover. The goal is a device that passes its first test and stays easy to work on for years after.
How an installation goes
First we look at the site, in person or by photo, to confirm what's needed and where it fits. Then you get a free quote covering the device, the work and the first test.
If permits or district approvals are required, we'll say so at the start and plan around them. Most homes and smaller commercial jobs take a single day.
After installation, we flush the line, test the device and send the first report to your district, which sets its annual due date. You get a copy, and we can remind you before the next test.
Installs for homes
Most residential installs are for new sprinkler systems, pools with auto-fill lines, wells or home fire sprinklers. The device is usually 3/4 inch or 1 inch, and the job takes a day or less.
We'll pick a spot that meets placement rules and is easy to reach for yearly testing, then test it and file the first report.
Larger projects
Business and construction projects tend to need plans, permits, bigger devices and coordination with other trades. Fire services commonly use detector assemblies 4 inches and larger.
We fit into your project timeline and file the startup test before final inspection.
Changes of use and new equipment
New equipment, like a boiler, chemical injector, wash bay or medical device, can raise the hazard at a connection. Turning a space into a different type of business can do the same. Either way, the district may ask for a new or upgraded device.
Planning a change? Call us early. Building the right device into the plan from the start costs less than retrofitting after an inspector catches it.
If you're unsure a device is even required, text us a photo and a quick description of the project. We'll let you know whether one is likely needed, which type and about what's involved, with no obligation. There's no charge for the quote, and most residential jobs are finished in a day.

Questions
Which type do I need?
Your water district decides based on how the water is used. We confirm it before we quote.
Is backflow testing really every year?
In California, backflow prevention assemblies must be tested at least once a year. They also need a test right after installation, after any repair, and after being moved. Your water district sets the exact due date and usually mails a notice before it.
Why Corona customers call us for backflow installation
We're a local company that focuses on backflow prevention. Every test is run by a certified tester with a calibrated gauge, and every report is filed with your water district as part of the job, not as an add-on.
You'll know the price before any work starts. Testing is a flat $105 per device under 4 inches and $175 for 4 inches and up, and repairs, replacements and installs are quoted first. We answer the phone seven days a week from 6am to 12pm, same-week appointments are normal, and emergency calls are taken 24/7.
