Your water heater is an essential appliance, ensuring warm showers and clean dishes, but when it starts leaking, it's cause for concern. A leaking water heater can lead to significant damage if not addressed promptly. Understanding the potential reasons behind a water heater leaking can help you decide when professional intervention is required.

1. Faulty Temperature and Pressure Relief Valve

One common reason your water heater might be leaking is due to a faulty temperature and pressure relief valve. This valve is a critical component that prevents your water heater from over-pressurizing. If it's malfunctioning or damaged, it could cause water to leak from the tank. In such cases, having a professional replace the valve often resolves the issue. According to Report Prime, the water heater repair market was expected to grow from $10.80 billion in 2024 to $16.13 billion by 2031, at a compound annual growth rate (CAGR) of 5.90% during the forecast period, highlighting the growing importance of addressing such issues promptly.

2. Damaged Drain Valve Causing Water Leakage

Another culprit could be the drain valve located at the bottom of your water heater. The drain valve might have become loose or damaged over time, resulting in water seeping out. It's a common issue given that this valve is used to empty the tank for maintenance purposes. Hiring a professional to check if the valve is securely tightened or replace it if broken can often solve the leakage problem. This fix should not be done alone, and we recommend a professional assess the issue first.

3. Corrosion Within the Water Heater Tank

Corrosion inside the tank is another reason your water heater might be leaking. Over time, minerals in water, especially if it's hard, can cause the inside of the tank to rust. Once the tank deteriorates to the point of leaking, replacement is the best option. Corrosion-related leaks signify that the tank's structural integrity is compromised, posing a risk of significant water damage if it fails, thus necessitating the need for professional help.

A leaking water heater is not an issue to take lightly, as the cost and potential damage can escalate quickly. Identifying the reason behind the leakage can save you time and money, whether it's a simple valve replacement or a more serious tank issue.
