Hose Bibb Vacuum Breakers in Hilmar, CA

A garden hose dropped into a bucket of weed killer is a cross-connection. If pressure on the street drops, that bucket can siphon back into your pipes.

A hose bibb vacuum breaker, built to ASSE 1011, threads onto the outdoor faucet and lets air in when pressure drops, breaking the siphon. Most plumbing codes require one on every hose connection.

The better ones have a breakaway set screw so they cannot be removed once installed. Frost-free sillcocks often come with a vacuum breaker built in, but the cheap plastic caps on some models crack after a few seasons. A faucet that sprays water from the top of the vacuum breaker when you shut the hose nozzle has a failed one.

These are not testable devices, so they are not on your utility's annual list. They still matter for backflow prevention at home.

Grizzly Backflow & Plumbing connects Hilmar, CA homeowners with plumbers who fit hose bibb vacuum breakers and check other small cross-connections during a backflow testing visit. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Hose Bibb Vacuum Breakers in Hilmar, 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.
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.
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.
