What our backflow prevention and testing service includes
Every backflow testing appointment covers the full scope of what your water district requires, plus the practical extras that keep your device running between tests.
Work order
Backflow Prevention and Testing- Full assembly inspection: We inspect the entire backflow assembly for leaks, corrosion, freeze damage, and improper installation. Test cocks, bonnets, and check valves all get a close look. If we spot a problem, we tell you before testing begins.
- Calibrated performance test: We test each check valve and relief port using a calibrated differential pressure gauge. Every reading is recorded on the state-approved form. The test confirms your device meets UPC and manufacturer specifications.
- Repair or rebuild if needed: If the assembly fails, we diagnose the issue and explain your options. Most failures are worn rubber discs or broken springs, which we can fix with a rebuild kit. We stock common parts so many repairs are done the same visit.
- Certification filing: We complete the test report and submit it to your water district on your behalf. You get a copy for your records. If your district requires a tag on the device, we attach it before we leave.
- Reminder scheduling: We note your next test due date and send you a reminder when it is coming up. That way you never miss a deadline or get caught off guard by a compliance notice. One less thing to track.

Tools and methods we use for backflow testing
Each method answers a different question. Together they leave very little to guess.
Used to remove test cocks, replace damaged components, and install new assemblies. We carry a range of sizes and common fittings so repairs can be completed on the same visit.
For quick, reliable repairs to supply lines connected to backflow devices. SharkBite fittings let us make secure connections without soldering, which speeds up repairs in tight spaces.
For permanent repairs and new installations where copper is the preferred material. We solder joints to code and pressure-test the line before returning the system to service.
Used to verify system pressure before and after testing. High or low pressure can affect device performance and may indicate a larger plumbing issue that needs attention.

PhotoFailed test to passing certification in one visit
Before: A homeowner in Whitney Ranch received a notice that their backflow device failed its annual test. The device was leaking slightly and the relief valve was not holding pressure. They were facing a compliance deadline and worried about a costly replacement.
After: We replaced the relief valve and check valve discs with a rebuild kit, retested the assembly, and it passed on the first try. The homeowner avoided a full replacement and met the deadline.
Commercial property back in compliance
Before: One device had failed its last test and was tagged out of service. The water district was threatening fines.
After: The property was back in compliance within 48 hours. The manager now has a single contact for all future testing.
Frozen assembly replaced before spring
Before: A homeowner in Sunset Whitney noticed water pooling near their backflow device after a cold snap. The brass body had cracked from freezing, and the device was leaking steadily. They needed a replacement before the irrigation season started.
After: The new device was installed with proper freeze protection. The homeowner was ready for spring irrigation without worrying about a failed test.
Backflow problems we solve for Rocklin properties
Backflow issues range from minor test failures to serious contamination risks. Here are the most common problems we see and how we fix them.
Failed annual backflow test
Your water district may issue fines or require immediate repair. Without a passing test, your property is out of compliance and at risk for enforcement action.
Overdue certification notice
Ignoring the notice can lead to penalties or water service issues. Many Rocklin districts require annual testing and will escalate if you do not respond.
Corroded or leaking assembly
A corroded device can fail its test, leak water, and eventually contaminate your supply. Small leaks also waste water and drive up your bill.
Improper installation by a previous contractor
A device installed at the wrong height or without proper clearances will fail inspection and may not protect your water supply.

What Rocklin customers say about our backflow testing
I got a notice from the water district saying my backflow test was overdue. Called these guys and they had a tester out the next morning. He tested the device, replaced a worn check valve, and filed the report the same day. No fines, no hassle. Exactly what I needed.
We manage several commercial properties and backflow testing is always a headache. Rocklin Granite Flow Plumbing scheduled all the tests in one week, filed every report, and gave us copies for our files. They even flagged two devices that needed replacement before they failed. Great communication throughout.
My irrigation backflow device failed its test and I was worried about a big repair bill. The technician showed me exactly what was wrong, quoted the rebuild kit price, and had it fixed in under an hour. Tested it again before he left and it passed. Honest work at a fair price.
