Hot Water Leak
Loose Drain Valve:
One of the most common causes of water heater leakage is a loose drain valve. It water appears to be leaking from the valve, try tightening it with a wrench until it is snug, but be careful not to over-tighten it.
Too Much Pressure:
Sometimes a water heater tank can build up too much pressure which can cause leaks. This can happen with the water temperature is set too high or the exterior water supply is coming in at too high of a pressure for the tank.
Cracked Storage Tank:
Hot water heaters are built with a glass-lined storage tank. Over time, the natural minerals in the water can calcify and create deposits on the inside of the tank. These can crack the glass lining and cause your water heater to leak. Also, as water is heated, it expands. Over time, this expansion creates stress on the glass lining of the heater and can cause it to crack.
Other Reasons:
Lose fixtures, improper draining, and just age, are all reasons that your water heater may be leaking.
It’s always a good idea to do some troubleshooting on your own, but having a professional come in will always be the safest and best way to avoid potential long-term and expensive damage to your home.
