Common Reasons For Water Heater Leaks

Leaky water heater

Though it may seem like a minor problem that can be swept under the proverbial rug, a water heater leak can swiftly become a major problem with serious repercussions. Prompt repairs are a must.

To prevent such problems from further escalating, you need to be aware of what causes them in the first place. Below, Griffin Service, the go-to name for water heater repair in Jacksonville, FL, discusses the most common reasons for water heater leaks.


Older water heaters–particularly those 15 years or older–have a higher leak rate than newer, modern models. There is a rise in the frequency of leaks and a gradual decline in the unit’s ability to keep water at a comfortable temperature as it ages, mostly due to wear and tear or lack of maintenance and water heater services.


Corrosion can cause a water heater to leak, which is a common problem in older appliances. When metal components rust, water leaks out of the crevices, necessitating prompt repairs or water heater replacement services depending on the severity of the damage.

High Water Pressure

High water pressure is a surefire recipe for disaster when it comes to plumbing. Even if your unit is still new because you’ve just had a water heater installation, too much pressure can significantly reduce your unit’s life expectancy.

Storage Tank Damage

A water heater’s capacity can be increased with an auxiliary tank, which is found in some models. The interior of these tanks is occasionally made of glass. Minerals accumulate and calcify on the glass surface over time. This won’t be an issue if you opt for a tankless water heater.

Most water heater leaks can be avoided by taking preventative measures. Make a note of the most common reasons for leaks so you can take the necessary precautionary steps. Even though some leaks are unavoidable, most homeowners have more sway over leaks than they give themselves credit for.
