How to Prevent PEX Pipe From Freezing

Preventing PEX pipe from freezing is essential to maintain the integrity of your plumbing system during cold weather. Here are some steps you can take to prevent PEX pipe freezing:

1. Insulate Pipes:

- Use pipe insulation specifically designed for PEX pipes.

- Ensure the insulation completely covers the pipes, with no gaps or exposed areas.

- Pay attention to areas where pipes are exposed, such as near exterior walls, crawl spaces, or attics.

2. Heat Tracing:

- If you live in an extremely cold climate, consider using heat tracing cables. These cables wrap around the pipes and provide a controlled amount of heat to prevent freezing.

3. Keep Cabinets Open:

- Allow warm air to circulate around the pipes by leaving cabinet doors open, particularly under sinks or in cabinets near exterior walls.

4. Seal Cracks and Drafts:

- Inspect your home for cracks or drafts around windows, doors, or any areas where cold air may enter.

- Seal any gaps using weatherstripping or caulk to keep warm air in.

5. Set a Low Thermostat:

- Keep the thermostat set to a temperature of at least 55°F (13°C), even when away from home, to maintain some heat in the house.

6. Use Space Heaters:

- If you have areas where pipes are particularly vulnerable to freezing, consider using space heaters to provide additional warmth in those specific locations.

7. Maintain Water Flow:

- Keep a small trickle of water flowing through faucets connected to exposed pipes. Running water is less likely to freeze than stagnant water.

8. Disconnect and Drain Hoses:

- Disconnect and drain any outdoor faucets, garden hoses, or irrigation systems to avoid freezing damage to these components.

9. Winterize Properly:

- If you're leaving your home vacant during extremely cold weather for an extended period, consider winterizing your plumbing system by draining and adding antifreeze to the pipes.

By following these preventive measures, you can help protect your PEX pipes from freezing and minimize the risk of costly damage to your plumbing system during the winter months.
