Backflow Test Report Filing in Modesto, CA

A passing test that never reaches the utility counts as a missed test. Plenty of property owners in Modesto, CA learn this from a second notice letter.

Grizzly Backflow & Plumbing connects you with testers who file the report with your water purveyor once the test is done. Many utilities now take submissions through an online portal and charge a small filing fee per device. Others still want the paper form, signed, with the tester's certification number and the test kit's calibration date on it.

The report lists the device make, model, size and serial number, the location, the readings for each check and the relief valve, and whether it passed. A typo in the serial number is the most common reason a report bounces, so testers copy it straight off the body tag.

You get a copy for your own records. Keep it. Some insurers and fire marshals ask for it.

If your utility has flagged a device as overdue, call (833) 990-5874 and mention the notice date so the report can go in quickly.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Backflow Test Report Filing in Modesto, CA.

Talk to a person
What is the difference between an RPZ and a double check valve?
Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.
Why is water dripping from my RPZ relief valve?
A steady drip usually means debris is holding the first check open or the relief valve diaphragm is worn. A cleaning or a rebuild kit fixes most cases.
How long does a backflow test take?
A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
Is fire sprinkler backflow testing different?
Yes. Along with the standard check valve test, NFPA 25 calls for an annual forward flow test on fire line backflow assemblies. Results often go to both the water utility and the fire authority.
