Find the main valve before winter
Walk the water line to the spot where it enters the house, in a basement, utility room, garage or crawl space, and hang a tag on the valve. In a flood nobody wants to search a crowded storage corner for it. A wheel closes clockwise and a lever swings a quarter turn.
Freezes in Colorado
Alamosa pipes face about 214 days a year at 32°F or colder and Denver pipes about 146, going by the ten years to 2024. Garages, crawl spaces and outside walls are where pipes give out first, and the pipe freeze risk checker rates the ones in your home.
Freezing days run from roughly 146 a year in Denver to 214 in Alamosa, so a heater or drain problem can follow a cold snap, and that cold also tests every other pipe in the house. Water heater repair and installation and drain cleaning are the likely next pages, and the home page covers everything else.
