Why is the Water Heater Leaking?

In most cases, older water heaters with a broken tank require a full replacement.

Finding a puddle around a water heater can be alarming, but thankfully there’s often a simple explanation and solution. The key is to act quickly and shut off the water, then bring in a professional to troubleshoot the leak.

Water heaters can leak for several different reasons. The constant temperature and pressure changes can cause components like rubber gaskets to wear out or corrode over time.

Pinpointing the Issue

Examine the water supply pipes and fittings to identify the source of the leak. It could be from the cold water line, the hot water pipe, or any other valves and components. To confirm the leak, dry the area using a spare rag or paper towels and observe if water reappears.

Leaks from Above

If a homeowner notices a water heater tank leak, investigate the source by following the water trail upward. What may seem like a tank leak could be a result of dripping from a pipe fitting located above the water heater.

Leaks from the Tank

Mineral deposits and rust can deteriorate the inside of a water heater tank, particularly in homes with hard water or if regular draining and flushing have been overlooked. A professional plumber may be able to offer repairs or patching solutions for certain leaking water heater tanks, but be prepared for the possibility of a water heater replacement.

Other Possibilities

Sometimes, a leak may stem from the drain valve on the side of the water heater tank, which can be easily replaced. Alternatively, excess condensation may be the culprit, especially if a homeowner frequently exhausts all their hot water, causing the tank to fill with cold water. In such cases, upgrading to a larger water heater could reduce the risk of water damage.

Repair or Replace

In most cases, older water heaters with a broken tank require a full replacement. A skilled plumber can quickly help prevent water damage to the home and restore the water heater back to normal.

Pressure Relief Valve Leaks

If the water heater leak is coming from the temperature and pressure relief valve, try lowering the temperature setting of the heater if it exceeds 120 degrees. Elevated temperatures can increase the pressure within the tank, leading to water seepage. If the leak persists, after making an adjustment, seek the assistance of a plumber to repair or replace the temperature and pressure relief valve.

Professional Assistance

If a leak is coming from a valve or fitting, it may need to be replaced. Most homeowners should get a licensed plumber to do this job. Precise fitting of the replacement part is essential, and it is prudent to check other fittings in the system, as they might be prone to failure as well.
