The time frame before water pipes burst due to freezing varies, but damage can occur in as little as a few hours under extreme conditions. Pipes are at risk when temperatures drop below 20°F (-6°C), especially if they're poorly insulated or exposed to cold air. It's crucial to prevent freezing by keeping your home adequately heated, insulating pipes, and allowing a trickle of water to flow through faucets during very cold weather to prevent bursting.
