The answer to 'why is my pipe leaking water' is that there are several common causes, including worn washers, damaged seals, pipe corrosion, high water pressure, or even tree root intrusion. Leaks can manifest as drips, sprays, or even small floods, and they can happen at joints, faucets, or along the pipe itself.
If the leak is small and isolated, it may be a DIY fix by replacing washers or tightening connections. However, if the leak is extensive, the pipe is old, or you're unsure of the cause, it's best to call a professional plumber. They can diagnose the issue, make necessary repairs, and ensure the problem is resolved safely and properly.
