“Sweating” Pipes

“Sweating” pipes and plumbing fixtures in summer time or during seasonal changes are not a sign of faulty plumbing. Due to condensation of water vapor in the air, beads of moisture will form in warm weather on any exposed pipes and fixtures containing cold water. When a toilet tank continues to “sweat” for hours after it has been used, it is a sign that cold water is continuing to flow through the toilet. This could be due to an improper adjustment of the tank valve or a leak.
