For many homeowners, a leaking water heater can be a major headache. Not only is it a potential safety hazard, but it can also cause significant water damage if not addressed promptly. There are many reasons why a water heater may be leaking, and it is important to understand the underlying cause to determine the best course of action.

Failed T&P Relief Valve

One of the most common causes of a leaking water heater is a failed temperature and pressure (T&P) relief valve. The T&P valve is designed to release excess pressure inside the tank if it becomes too high, preventing the tank from exploding. If the valve is faulty or has failed, it can cause water to leak from the tank. To fix this issue, the T&P relief valve may need to be replaced.

Corrosion

Another reason for a leaking water heater is corrosion. Over time, the inside of the tank may corrode, causing small holes to form. If the corrosion is located at the bottom of the tank, the water will leak out of the bottom. Unfortunately, if the tank is corroded, it is usually not repairable, and a new water heater may be required.

Loose Connections

Sometimes, water heater leaks may be caused by loose connections. The inlet and outlet pipes that connect the water heater to the plumbing system may become loose over time. If this happens, water can leak from the connections. To fix this problem, the connections may need to be tightened or replaced.

High Water Pressure

If your home has high water pressure, it can put extra strain on your water heater and cause it to leak. The excess pressure can cause the T&P valve to release, or it can cause the tank to burst. To prevent water heater leaks caused by high water pressure, consider installing a pressure regulator.

When to Hire a Professional

If you are not comfortable diagnosing or repairing your water heater, it is best to hire a professional plumber. A licensed plumber can assess the problem and recommend the best course of action. Additionally, if your water heater is old or has been leaking for some time, it may be time to consider replacing it.

A leaking water heater is not something to ignore. Not only can it damage your home, but it can also cause serious injury if not repaired properly. By understanding the common causes of water heater leaks and when to hire a professional, you can take steps to prevent and repair leaks as necessary.
