Utility faucets installed on the outside of a residential building are commonly referred to as what?

Utility faucets installed on the outside of a residential building are commonly referred to as hose bibbs. This term specifically describes the type of faucet that connects to a garden hose, allowing for easy access to water for outdoor tasks such as gardening, washing cars, or filling pools. Hose bibbs typically feature a threaded outlet where a hose can be securely attached, making them versatile and useful for various outdoor water needs.

The designation of "hose bibb" helps differentiate these types of faucets from other outdoor faucets, as it emphasizes their functionality related to hoses. The structure of a hose bibb is designed to prevent backflow and ensure that water flows efficiently while also being weather-resistant to withstand outdoor conditions. This is crucial for maintaining water quality and preventing plumbing issues.
