If a hose bib is not properly winterized, what can occur?

When a hose bib is not properly winterized, it can fill with water that subsequently freezes during cold weather. When water freezes, it expands, leading to increased pressure within the hose bib and connected plumbing. This pressure can cause the pipe to crack or burst, resulting in leaks. Such damage may not only affect the hose bib itself but can also lead to further plumbing issues, creating the potential for water damage and requiring repairs. Therefore, proper winterization, such as draining the hose bib and ensuring it is insulated, is critical to prevent this costly and damaging scenario.
