When there is a leak around your home it is a problem. It can lead to mold and water damage among water waste. At the end of the day, leaks are never good and no one wants to leave them to worsen.
A leak in any part of your house is bad news of course but one in your water heater can be a bigger worry than a pinhole leak under the sink. Why? Because a water heater leak can mean you need water heater repairs or even a replacement. The question is how do you know which one it is?
