Hose Bibb Vacuum Breakers in San Jose, 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 San Jose, 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 San Jose, CA.

Talk to a person
How often does a backflow preventer need testing in San Jose, 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.
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.
How much does backflow testing cost in San Jose, CA?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in San Jose, CA.
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.
