About Grizzly Backflow & Plumbing

Backflow Testing Company in San Carlos, CA Near Me

California's cross-connection rules, long known as Title 17 and now set by the State Water Resources Control Board, require water suppliers in San Carlos, CA to keep a list of every backflow assembly and collect a passing test each year.

Many utilities accept reports only from testers certified by an approved body such as the AWWA California-Nevada Section. Recycled water lines add another layer: sites with purple pipe often need an RPZ on the potable service. Grizzly Backflow & Plumbing connects San Carlos, CA property owners with certified testers for annual backflow testing, RPZ valve testing and test report filing. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions San Carlos, CA property owners ask about backflow testing and backflow prevention.

Talk to a person
How often does a backflow preventer need testing in San Carlos, CA?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
What happens if I miss the backflow test deadline?
Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.
Will my water be off during the test?
Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.
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.
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.
