Annual Backflow Testing in Whittier, CA

Your water utility mailed a notice. It names a device, a serial number and a due date. That letter is the start of annual backflow testing, and Grizzly Backflow & Plumbing connects you with a local tester in Whittier, CA who can handle it.

The tester closes the downstream shutoff, hooks a differential pressure gauge to the test cocks and reads each check valve in turn. On a double check, each check has to hold at least 1.0 psid. On an RPZ, the relief valve has to open at no less than 2.0 psid. The numbers go on the report exactly as read.

Most residential tests take about half an hour, and your water is off for part of it. Commercial assemblies take longer, especially 4 inch and larger devices.

If the device passes, the report gets filed. If it fails, you get the reason in plain words and the options: repair, rebuild or replace.

Backflow prevention only works when the device is checked on schedule. Call Grizzly Backflow & Plumbing at (833) 990-5874 to book your test in Whittier, CA.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Annual Backflow Testing in Whittier, CA.

Talk to a person
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.
What does a failed backflow test mean?
A check valve or the relief valve did not hold its required pressure differential. The device needs repair or replacement, then a retest before a passing report can be filed.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
