Why yearly testing matters in Redlands
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.
Which testing page fits your situation
For most customers, the right service is the standard annual test. That's what a district notice is asking for. The pages below explain how the test works and what's different about each device type.
A few situations have their own page. If you have several devices, see multi-device pricing. If you're up against a shutoff date, closing or inspection, see emergency testing. Certification for a sale and cross-connection surveys for commercial sites are covered separately as well.
If you're unsure, give us a call. A quick description of your property is usually enough for us to point you the right way.
Our backflow testing services in Redlands
Annual Backflow Testing
Every backflow device in California needs a passing test at least once a year. We schedule it before your due date, take the readings with a calibrated gauge, and send the report to your district. Flat pricing: $105 under 4 inches, $175 for 4 inches and larger. You'll get a copy of every report by email for your records. 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
A field test with a calibrated differential pressure gauge, run to the procedure your water district accepts. We check each check valve, the relief valve on RPs and the air inlet on vacuum breakers, then record the readings on your district's report. Most assemblies take 20 to 45 minutes. You get a copy of the readings for your records. 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
Lower pricing for property managers, HOAs, schools and businesses with more than one device. Testing them together saves travel and setup, and the price per device drops. Every list is different, so call for multi-device pricing and we'll give you one quote for everything. Pair it with due date management to keep every device on schedule. More about multi-device backflow testing discount.
Backflow Inspection
A close look at your backflow device and its setup: valves, test cocks, leaks, clearance, drainage and damage. We do it with every test and note anything that could cause trouble later. Need an inspection on its own, before a sale or after a freeze? Call and we'll set it up. 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
We follow your water lines from the meter to every point of use, noting each cross-connection and whether it has the right backflow protection. Districts often ask for this at commercial and multi-unit properties. Afterward you get a written summary and a quote for anything that needs a device. We'll confirm what your district requires before we start. More about cross-connection inspection.
Emergency Backflow Testing
Need a passing backflow report fast? Call any time. We prioritize final notices, closings and inspections, often testing same day or next morning, and file the report as soon as it passes. Same flat pricing by size, with any after-hours charge quoted on the phone first. We can email the report straight to escrow or an inspector. More about emergency backflow testing.
Questions
How often do I need a backflow test?
Once a year at minimum. A device also needs testing right after it's installed, repaired or moved. Your water district picks the due date and normally mails a reminder ahead of time.
Do I need to be there for the test?
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.
