Short freezes leave exposed plumbing vulnerable
Potosi’s generally warm weather can leave exposed plumbing easy to overlook until a sharp winter cold snap arrives. Pipes at exterior walls, in crawlspaces, through attics, at hose connections, or in unconditioned buildings are exposed to cold and wind in ways that the rest of the plumbing often is not. Ice can form in one of these runs while water continues normally elsewhere in the house.
That pattern matters when a frozen line needs thawing. The goal is not simply to get water moving again: the pipe needs controlled heat, and it needs to be checked as it warms. A frozen pipe can conceal a crack while the ice is holding everything still; once flow returns, a split can become visible.
After a freeze, protecting the exposed parts of the system is more involved than putting insulation around one accessible pipe. Disconnecting hoses, shielding exterior faucets, insulating vulnerable runs, closing openings that let cold air reach plumbing, and knowing where the main shutoff is located all address the places where intermittent freezes put the greatest strain on a home.
