Hose Bibb Vacuum Breakers in Milwaukee, WI

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 Milwaukee, WI 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 Milwaukee, WI.

Talk to a person
How often does a backflow preventer need testing in Milwaukee, WI?
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 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.
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
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.
