What Is A Hose Bib?

A hose bib, also interchangeably referred to as a water spigot, is an outdoor faucet that provides access to your home's water supply. Typically installed on the sidewall of a house, it's a helpful tool that allows ease access and connection to garden hoses, perfect for gardening, cleaning, and various other activities.

Hose Bib Codes And Regulations

Hose bibs are regulated to ensure they meet specific safety and performance standards, which can vary depending on the location. Here are some examples of the most common codes and regulations that apply to hose bibs:

 Standard/Regulation Description
ASSE 1019 Specifies performance requirements for frost-proof and non-frost-proof hose bibs to withstand freezing temperatures without bursting.
Uniform Plumbing Code (UPC) Mandates the installation of an approved backflow prevention device on all hose bibs to prevent contaminated water from siphoning back into the clean water supply.
Lead-free Legislation Requires all hose bibs in the United States to be "lead-free" as defined by the Safe Drinking Water Act, containing less than 0.25% lead on surfaces in contact with drinking water.
Energy Policy Act Includes requirements for hose bibs regarding water efficiency, reducing water waste by specifying flow rates, and other performance criteria.

Common Outdoor Hose Bib Issues

Since hose bibs are commonly installed outdoors, they are more prone to issues caused by the environment and general wear and tear. It is key to address these common issues promptly to save time and money on more extensive repairs and help ensure that the hose bib continues to function properly for years to come. To do this, it is important to learn how to identify common issues in outdoor faucets:

  • Rust - Over time, metal hose bibbs can suffer from rust due to exposure to moisture and environmental elements. Rust not only weakens the structural integrity of the hose bib but can also obstruct water flow or cause leaks.
  • Leaks - A common issue with hose bibs is leaking, which can occur at the spout, handle, or connection points. Leaks are often caused by worn-out washers, O-rings, or internal seals.
  • Worn Threads - The threads on a hose bibb can become worn or damaged from repeated use or over-tightening of connections. This can lead to a poor seal between the hose bib and the hose, causing leaks or difficulty attaching the hose. Thread tape or a hose thread repair kit can sometimes remedy this issue, but severely damaged threads may require replacing the entire water spigot.
  • Handle And Valve Issues - Handles can become difficult to turn over time due to mineral buildup, corrosion, or wear and tear on the internal mechanisms. Similarly, the valve inside the hose bib may fail to fully open or close, which can result in a constant drip or inability to shut off the Freezing- In colder climates, water remaining in the hose bib can freeze, expand, and cause the pipe to crack or burst. This issue is most prevalent in non-frost-proof hose bibs.
  • Pressure Problems - Excessive water pressure can lead to hose bib failure, as it strains the valves and seals, potentially causing leaks or bursts. Installing a pressure regulator can help maintain a safe water pressure level and extend the life of the hose bib.
  • Backflow - Backflow occurs when contaminated water reverses direction and enters the clean water supply. This can happen in situations where the hose is submerged in a contaminant or there is a significant pressure change in the water system.
