Understanding Water Heater Leaks: Causes and Solutions

Common Causes of Water Heater Leaks

1. Old Age and Wear
   Over time, water heaters can corrode, leading to leaks. If your water heater is more than 10-15 years old, it may be nearing the end of its lifespan. Rust and sediment buildup can weaken the tank, causing it to leak. Regular maintenance can help delay this process, but replacement is often inevitable.

2. Loose Connections
   The inlet and outlet connections on your water heater can loosen over time, especially if the unit experiences frequent temperature changes. This can result in water dripping from the top of the tank. Checking these connections periodically can help catch issues early.

3. Faulty Pressure Relief Valve
   The pressure relief valve is a safety feature that releases excess pressure from the tank. If this valve malfunctions, it can cause leaks or even flooding. Regular inspections can ensure it’s functioning properly.

4. Cracked Tank
   Extreme temperature fluctuations or manufacturing defects can cause cracks in the water heater tank. These cracks often start small but can quickly lead to significant leaks, especially under pressure.

Solutions for Water Heater Leaks

1. Tighten Loose Connections
   Check the connections at the top of the water heater and tighten them if necessary. If the leak persists, the fittings may need to be replaced.

2. Replace the Pressure Relief Valve
   If the valve is leaking, replacing it is a relatively simple fix. However, if you’re unsure how to proceed, Bear Plumbing can handle it for you quickly and efficiently.

3. Flush the Tank
   Regularly flushing your water heater can remove sediment buildup and extend its lifespan. If sediment has already caused damage, a replacement may be necessary.

4. Repair or Replace the Unit
   For severe issues, such as a cracked tank, replacing the water heater is often the best solution. Bear Plumbing can help you choose the right unit for your needs and install it professionally.

Preventing Future Leaks

• Schedule annual maintenance to inspect your water heater for signs of wear and tear.
