Top 4 Reasons Your Water Heater Could Be Leaking

Water heaters are necessary for our daily comfort, but nothing disrupts your rhythm more than discovering a leak. At Mister Water Heater, we’ve offered water heater repair services to residents in the Indianapolis area for decades now. We’ve seen firsthand how a leak can transform from a minor inconvenience to causing real damage to your home. Let’s take a look at four possible reasons your water heater might be leaking and how our plumbers can help you address the problem.

1. Corrosion

Corrosion is a common cause of water heater leaks. Over time, the metal tank can rust, creating holes and allowing water to escape. This is more common in older units, but even newer models can suffer if they aren’t maintained properly. Regular inspections can help detect and address corrosion early on.

2. Loose Connections

Water heaters rely on a series of connections that can become loose over time because of the continuous pressure and heating cycles. Whether you have a gas water heater, electric water heater, or even a hybrid unit, checking and tightening any loose connections can often resolve minor leaks.

3. Faulty Pressure Relief Valve

The pressure relief valve is a safety feature found in all water heaters, including tank, tankless, and energy-efficient models. If this valve is faulty or set incorrectly, it could cause water to leak from the tank. Regular maintenance checks by a professional can ensure this valve is working correctly.

4. Cracked Storage Tank

If your water heater has an internal storage tank, a crack in the tank can cause leaking. This can be due to the age of the unit or a manufacturing defect. If this is your issue, we offer professional water heater replacement services.

Issues With the Drain Valve

At the base of your water heater, there's a drain valve used for maintenance and cleaning. If this valve is not completely closed or is faulty, it can cause leaks. Sometimes, the valve simply needs to be tightened, but in other cases, it might need to be replaced.
