Why Is My Water Heater Leaking?

To assist our valued Idaho customers, our expert team at Western Heating & Air Conditioning compiled a list of the most common reasons for leaks.

Still unsure about the cause of your water heater leak? No problem! Call our Boise office, describe the issue, and our experts can provide professional advice.

1. Built-Up Moisture

A tiny amount of moisture on the exterior of your tank is normal. During the heating process, the metal expands and contracts due to temperature change. Over time, this can create small fractures that leak minuscule amounts of water. As the temperature lowers, these tiny leaks should stop. However, call us if the leaking continues or is high in water volume.

2. Leaky Temperature and Pressure Relief (T and P) Valve

Every storage tank has a temperature and pressure relief (T and P) valve. This valve regulates water pressure, ensuring it remains at a safe level. If your tank gets too hot, the valve opens up to cool down the water and release pressure.

If it drips occasionally, this indicates it’s doing its job. However, a constant leak may indicate a problem with thermal expansion or an issue with the valve itself. In this case, call a professional for service.

3. Leaky Drain Valve

The drain valve is for flushing your water heater, an important part of maintenance that you should schedule at least once a year. If you notice it leaking, try tightening it with a wrench. If this doesn’t work, you may need a replacement.

4. Rusted Tank

Storage tanks will last 10 to 12 years before they slow down. Over their lifespan, they can become rusted. This process is accelerated if the anode rod hasn’t been replaced every three to four years. The rust can cause the tank to deteriorate, losing its ability to hold water. Additionally, you may notice other symptoms like discolored water. In most cases, a rusted tank warrants a full replacement.
