Yes – All outdoor faucets and hose bibs that have threaded connections where a garden hose can be attached are required to have backflow prevention protection. This may be in the form of a frost-proof automatic draining outdoor faucet with built in backflow preventer or by the use of a screw on hose bibb vacuum breaker (HBVB) that can be purchased at local hardware or home supply stores.
