Backflow Enclosure and Freeze Protection in Los Angeles, CA

One hard night below 20 degrees is enough to split the bronze body of an exposed backflow preventer. The repair after a freeze is often a full replacement.

Freeze protection comes in a few forms. Insulated bags work for mild climates and short cold spells. Rigid insulated enclosures, built to the ASSE 1060 standard, add a heat source like a self-regulating cable or a small heater for places with long winters. On irrigation, draining the device through the test cocks and opening the ball valves halfway is the standard winter routine.

Enclosures need to be sized for the device and keep the relief port of an RPZ free to drain. A box with no drain opening can flood when the relief valve dumps.

Theft is a side issue. Brass backflow devices get stolen for scrap, and a locked enclosure helps.

Grizzly Backflow & Plumbing connects Los Angeles, CA owners with installers who fit enclosures and freeze protection, then schedule backflow testing once the device is back in service. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Backflow Enclosure and Freeze Protection in Los Angeles, CA.

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.
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.
Who sends the test report to the water utility?
The tester usually files it, either on the utility's paper form or through its online portal. Ask for a copy for your own records.
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.
