About Grizzly Backflow & Plumbing

Backflow Testing Company in Thousand Oaks, 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 Thousand Oaks, 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.

Backflow testing FAQs

Questions about backflow testing

Questions Thousand Oaks, CA property owners ask about backflow testing and backflow prevention.

Talk to a person
Who is allowed to test my backflow device?
A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.
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.
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.
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.
