If you\u2019ve ever gone down to your basement to escape the heat on a hot summer afternoon, you may have noticed beads of water covering your cold-water pipes and wondered, \u201cAre my pipes leaking?\u201d or \u201cWhy are my pipes sweating?\u201d This is a common phenomenon during Minnesota summers, but it doesn\u2019t necessarily mean your basement is in danger of flooding. In this blog, we\u2019ll help you distinguish between a harmless case of condensation and a genuine plumbing leak and give you steps to keep your basement dry.<\/p>\n\n\n\n

The Science: Why Pipes Sweat<\/h2>\n\n\n\n

You\u2019ve probably noticed drops of water on the glass if you\u2019ve ever had a cold drink on a hot, humid day. This is known as condensation, and it\u2019s the same phenomenon that happens to cold-water pipes during the summer. Condensation occurs when warm, moisture-heavy air touches a colder surface and cools rapidly. Because cold air can\u2019t hold as much water vapor as warm air, the excess moisture transitions from gas into liquid water droplets.<\/p>\n\n\n\n

Since Minnesota summers tend to be hot and humid, sweating pipes are a common occurrence.<\/p>\n\n\n\n
