Yes, pipes absolutely can freeze in Kelsey despite California’s generally mild climate. Your elevation of 1,923 feet means you experience colder temperatures than lower areas, and it only takes a few hours of below-freezing weather for water in pipes to turn to ice.
The Mediterranean climate creates a false sense of security, but even Texas saw devastating frozen pipe damage during their 2021 winter storm. Kelsey’s winter nights can drop well below freezing, especially in January and February.
Pipes in unheated areas like crawl spaces, attics, or exterior walls are most vulnerable. The expanding ice creates tremendous pressure that can burst pipes instantly, leading to thousands in water damage.
