why is my supply line frozen

Plumbing

The answer to 'why is my supply line frozen' is that the supply line, which carries water to your plumbing fixtures, has become frozen due to cold temperatures. This is a common issue during the winter months, especially in areas with prolonged freezing weather.

Some common causes of a frozen supply line include insufficient insulation, drafts around the pipes, or the line being located in an unheated area of your home. Symptoms may include reduced or no water flow, as well as the pipe feeling cold or icy to the touch.
