Hose Bibb Vacuum Breakers in Pembroke, NH

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 Pembroke, NH 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 Pembroke, NH.

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