Preventing Frozen Pipes: Actions to Take Starting in September

September 8th, 2025

With autumn approaching, it’s important to prepare your plumbing system to avoid the
problems caused by freezing temperatures. By taking action in September, you can
protect your pipes and avoid costly winter repairs.

1. Insulate Exposed Pipes
Pipes located in unheated areas such as basements, garages, or crawl spaces are
particularly vulnerable to freezing. Install insulating sleeves or foam pipe covers to retain
heat and reduce the risk of freezing.

2. Drain Outdoor Water Lines
Before the first frost, shut off the water supply to outdoor faucets and completely drain
the lines. This prevents standing water from freezing and causing cracks or bursts.

3. Check for Leaks and Needed Repairs
Minor leaks can turn into major problems in winter. Inspect your pipes, faucets, and
joints for any signs of leaks and repair them immediately.

4. Maintain a Minimum Indoor Temperature
Even if you are away, keep your heating set to at least 15°C (59°F) to prevent pipes from
freezing. Also, keep cabinet doors under sinks open to allow warm air to circulate.

5. Install a Monitoring System
For secondary residences or during extended absences, a leak detection or low-
temperature monitoring system can alert you before a problem becomes critical.

In summary, preparing your pipes in September is an investment in peace of mind.
Proactive prevention will help you face the winter confidently while avoiding costly
damage.
