Spring is in the air, and the seasonal thaw has started. As regular precipitation returns to North America this increase of humidity poses a huge risk for pipes that are vulnerable to Corrosion Under Insulation, or as it is more commonly identified, CUI. Each year, undetected CUI issues cause millions of dollars of damage due to pipe failures, flooding, and other such issues. Knowing what to look for, as well as the causes of CUI can help you catch rust and corrosion before it has the chance to progress to pipe failure. Learn more about CUI below, as well as some key ways to detect early signs of it.
