Common Causes of Water Heater Leaks
7063837684 • February 21, 2025
Water heaters ensure a steady hot water supply for cooking, cleaning, and bathing, especially during the colder months. Because of this, issues like leaks that disrupt proper heater functionality can cause inconvenience in your household. In addition, if this problem is left unaddressed, it can result in more severe issues, like water damage or flooding. Read on for some common causes of water heater leaks:
High Pressure
Water heaters
naturally create pressure when running. The hot water in their tank creates steam, increasing overall pressure. When this becomes excessive, and the steam has nowhere to go, it finds a way to escape, resulting in water leaking from existing cracks or loose connections.
Excess pressure in your water heater may be caused by setting water temperatures too high. A faulty temperature and pressure relief valve, which ensures a stable temperature in your water heater, may also be the culprit. A professional can help you diagnose these factors and ensure they will not cause your unit to leak.
Loose Drain Valve
The drain valve allows you to empty the water heater when cleaning the tank or for necessary maintenance and repairs. Over time, this component can loosen or become worn out, allowing water to leak out. While tightening the valve can help solve the issue, some situations call for a replacement. If you're unsure about the ideal solution, it's best to consult a plumber.
Sediment Buildup
As water heaters age, sediment buildup may occur. Aside from affecting your unit’s efficiency, these sediments can settle and build up at the bottom of the tank, causing deterioration. If your water heater tank cracks, it will likely leak, requiring costly replacement. To prevent sediment buildup, regular flushing and maintenance are a must.
Corroded Anode Rod
The anode rod is a component found inside the water heater tank. It attracts corrosive materials and prevents them from wreaking havoc on your unit. Although effective, this rod can become worn down over time. Without it, the corrosive substances can eat away at your tank until it cracks and leaks. Replacing the anode rod occasionally or when needed minimizes the chances of corrosion, which results in a leaking water heater.
