Discovering a puddle of water around your toilet, water heater, or beneath a dripping pipe just might send you running for the phone in a panic. Before you call a plumber, consider whether you’re witnessing a bona fide leak or just a bit of old-fashioned “sweating.”
Watch The Weather
In humid, warm weather some pipes and fixtures are more prone to “perspiration”. Cold water inside a pipe, toilet tank, or water heater will make the materials in which it’s contained cooler than the outside temperature. As a result, moisture in the air condenses on the surface, causing beads of water to accumulate. Depending on the level of humidity as well as the temperature difference, this can cause enough condensation to form puddles.
Before you panic over a potential leak, check the weather as well as accumulated condensation on the ceramic of your toilet tank, all along the cold-water pipe, or upon the metal casing of your water tank. This kind of condensation is most common in areas that are not temperature-controlled, like basements or attics.
