Which action helps ensure piping is not subject to freezing in cold weather?

• A. Care should be taken during installation.
• B. Keep piping outdoors in cold weather.
• C. Use only uninsulated piping.
• D. Rely on ambient heat to prevent freezing.

Answer: (A)

Preventing freezing in cold weather comes from how the piping is installed and protected. If installation is done with proper planning, you can route piping away from exposed outdoor areas, insulate any sections that will be near or in freezing temperatures, and add provisions like heat tracing or drainage where needed. This upfront protection keeps water in the lines from freezing, even when outdoor conditions are severe. Relying on ambient heat or leaving piping uninsulated increases the chance of freezing, and keeping piping outdoors in cold weather directly raises the risk. So, care during installation is the most reliable way to prevent freezing.
