Why yearly testing matters in Corona
Every backflow device on a water line guards the public supply. When street pressure drops, from a main break, hydrant use or a heat wave, water can reverse direction. A device that doesn't seal lets sprinkler water, chemicals or equipment water flow back toward your neighbors' taps.
That's why districts require a test each year. The rubber, springs and seats inside wear with time and debris, and only a gauge reading shows whether they still hold.
A yearly test keeps the supply safe and keeps you off the district's late list. It's quick, priced flat by size, and we file the report with the district for you.
Choosing the right testing service
Most people just need a standard annual test. If you got a notice, that's what it's asking for. If you're curious about how the test works or what your device type involves, the pages below go into more detail.
Some situations call for something specific. Property managers and businesses with several devices should look at multi-device pricing. Anyone facing a final notice, a closing date or an inspection should see emergency testing. If a buyer or inspector asked for a certification, or the district wants a cross-connection survey, those have their own pages too.
Not sure? Call and describe what you have. We'll tell you what you need in a minute or two.
Our backflow testing services in Corona
Annual Backflow Testing
The once-a-year test your water district requires for every backflow device. We test it, file the passing report with the district and note your next due date. Pricing is a flat $105 per device under 4 inches and $175 for 4 inches and up, with filing included. Same-week appointments are normal across Corona and nearby cities. More about annual backflow testing.
Backflow Preventer Testing
Testing for every common type of backflow preventer: RP, double check, PVB, SVB and fire line detector assemblies. We use the right procedure for your device, record the readings and file the report. Pricing goes by size, not type, at $105 under 4 inches and $175 for 4 inches and up. More about backflow preventer testing.
Backflow Assembly Testing
How the test actually works: a certified tester connects a calibrated gauge to the test cocks, isolates each valve and measures whether it holds. Readings go straight onto the district report, which we file for you. A typical assembly is done in 20 to 45 minutes. If a reading fails, you see it and get a repair price first. More about backflow assembly testing.
Backflow Device Testing
Backflow device testing for homes, irrigation systems, pools and small businesses. If you got a notice from your water district, we'll find the device, test it and file the report for you. Most home devices are under 4 inches, so the flat $105 price applies, and you usually don't need to be home. More about backflow device testing.
Multi-Device Backflow Testing Discount
Testing several backflow devices at one property, or across several properties? We test them on the same visit or route and pass the savings on. Pricing depends on how many devices you have and where they are, so call for multi-device pricing and we'll quote the whole list at once. More about multi-device backflow testing discount.
Backflow Inspection
Passing readings are only part of the picture. Our inspection checks how the device is installed, whether it can drain and be accessed, and whether anything is worn, leaking or damaged. It's included with every test, and available by itself if you call. Anything we find comes with a plain explanation and a price. More about backflow inspection.
Backflow Certification
Get your backflow device certified with a current passing report. We handle the test, any repair, the retest and the filing, then email you a copy. Common for property sales, new construction and lease renewals. Short deadline? Tell us when you call. Your certification stays current until next year's due date. More about backflow certification.
Cross-Connection Inspection
A walk-through of your property to find every point where drinking water could mix with something harmful, and to check whether each one is protected. Common for restaurants, clinics, schools and multi-unit buildings, or after a change of use. You get a written list, and we can install any protection needed. More about cross-connection inspection.
Emergency Backflow Testing
Final notice, shutoff date, escrow deadline or an inspector waiting on a report? Emergency calls are answered 24/7, and rush tests go to the front of the line. We test, repair if needed and file the passing report the same day. Pricing stays $105 under 4 inches and $175 for 4 inches and up. More about emergency backflow testing.
Questions
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.
Does someone need to meet the tester?
Usually not. If the assembly is accessible, we can test without you on site. We just need gate codes, keys to any locking cage, and a contact number in case we find a problem.
What to expect when you book backflow testing
Booking takes a couple of minutes by phone or online. We confirm the address, the device and how to reach it, and we'll give you a time window that works for you. For most homes, you don't need to be there.
On the visit, a certified tester does the work with a calibrated gauge and explains anything that comes up in plain terms. If a repair is needed, you'll get the price before anything happens. When the device passes, we send the report to your water district and email you a copy. Our office is open seven days a week, 6am to 12pm, and emergency calls are answered around the clock.
