In the event of a water leak, what is the first step a homeowner should take?

Shutting off the main water supply is the first critical step a homeowner should take in the event of a water leak. This action immediately stops the flow of water, preventing further damage to the property and minimizing the risk of water pooling, which can lead to more extensive issues such as mold growth, structural damage, or electrical hazards.

While checking for the source of the leak or calling a plumber are important steps that may follow, they should occur after securing the main water supply. Using towels to absorb water is also a temporary measure that does not address the root of the problem and could lead to excessive damage if the leak continues. Hence, turning off the main water supply is a proactive first response that preserves the integrity of the home and ensures safety before any further actions are taken.
