A leaking water heater may seem like a minor inconvenience, but when left untreated, it can quickly escalate into a more significant problem. Even small leaks can cause damage that may lead to potentially costly water heater repairs, as well as additional repairs to your floors and walls. The following guide will help you identify standard sources of leaks and how to avoid and fix them.

What Are the Common Causes of Water Heater Leaks?

1. Leaking Supply Lines

Supply lines at the top of a water heater are responsible for sending water into the tank. Occasionally, loose fittings or cracked flex tubes can cause leaks that drip down the side of the machine, making it appear as though the tank has sprung a leak.

Fortunately, a faulty supply line is a relatively easy and inexpensive water heater repair. Before replacing it, turn off the water supply.

2. Condensation Build-Up

When the tank is full of cold water, a certain amount of condensation may naturally form on the outside when the burner is on. Dripping from excess condensation can make it appear to be leaking when it's not.

While this is typical, excessive condensation can cause pilot outages when water runs down the flue tube onto the main burner. Proper ventilation and air circulation can reduce condensation on your water heater.

3. An Old Tank

Water heaters are built to last for several years. However, as they age, rust and corrosion can lead to fissures resulting in leaks in the bottom of the tank. While the cracks may appear small, they’re always an indication your water heater has reached the end of its life and should be replaced. Ignoring a damaged tank will eventually result in complete failure, and is often followed by major flooding.
