A water heater leak can quickly turn into a much bigger problem if not dealt with quickly. What starts out as a minor trickle can become a flood that causes water damage to floors, walls, and any items nearby.

And because most water heaters are located in a part of the house that doesn’t get much traffic, a leak can go unnoticed for weeks, or even months. To prevent a water heater leak from causing significant damage, it’s crucial to detect it early on before it’s too late.

Your local plumbing expert can help diagnose the root problem to figure out whether your water heater needs a small repair or a full replacement.

If you’re wondering what causes a water heater to leak, here are a few of the most common reasons to keep in mind.

Sediment Buildup

Over time, sediment can start collecting at the bottom of your water heater tank. If not drained and cleaned regularly, the sediment will build to the point where cracks start to form. This results in water leaking through the sediment cracks.

Homeowners that make sure to clean their water heater tanks almost never have to worry about this issue. That’s why it’s important to schedule regular maintenance check-ups with your local plumbing company to extend the life of your water heater.

Temperature And Pressure Relief Valve

Also called the T&P valve, the temperature and pressure relief valve releases pressure from inside the tank. When this valve is damaged, this results in a pressure increase inside the tank.

Occasionally, the valve may just need to be tightened. But other cases might require a replacement, so it’s worth checking with a plumber before dealing with any T&P valve problems.

Old Tank

Sometimes a water heater leak is simply the result of old age. Older models of tank water heaters tend to leak more often than newer ones, especially if it’s over 15 years old.

As the years go by, the water heater becomes less efficient as parts wear out. Aged water heaters are also prone to rust developing in the tank, which can cause leaks from corrosion. If your water heater is acting up due to old age, the best thing to do is just get a replacement.

Loose Drain Valve

The drain valve is used to empty the tank during maintenance check-ups and cleanings. All that wear and tear can eventually loosen the drain valve, allowing water to leak through.

If the leak is coming from the base of the valve, this means the valve isn’t watertight. In this situation, a new drain valve is often required.
