Upon noticing a water leak, what is the proper first step to take?

Turning off the water supply is the proper first step when noticing a water leak because it immediately stops the flow of water, thus minimizing damage to the property. This prevents further flooding and helps control the situation until a professional can assess and address the leak properly. Maintaining control over water flow is crucial in any leak scenario because it significantly mitigates the risk of water damage, mold growth, or structural issues that can arise from uncontrolled leaking.

Once the water is turned off, it becomes safer to investigate the source of the leak and evaluate the necessary repairs, making it a foundational action that should be prioritized in any plumbing emergency. Addressing the leak in this manner sets up a clear path toward a more effective and less damaging response to the situation.
