3 Causes Of A Leaking or Burst Water Heater

A faulty water heater is one of the top sources of residential water damage. Not only are issues with your water heater a total nuisance, but they are expensive to fix! That’s why it’s important to know the causes of a leaking or burst water heater—that way, you’ll know how to prevent the problem in the first place. 

3 Causes of a Leaking or Burst Water Heater

Don’t let issues with your water heater go on for too long. Learn what’s causing the issue so you can prevent it from happening again in the future!

Sediment Build-up 

If your water heater is making a popping or knocking noise, then you might be dealing with sediment build-up. Over time, sediment—the minerals in your hard water—will create a layer at the bottom of your water heater tank. The sediment acts as a barrier between the water and the burner. This forces the burner to run longer, which will cause overheating; this will deteriorate the tank. 

The solution: 

This problem can be prevented by flushing and draining your home’s water heater tank of sediment once a year.

Rust Corrosion 

If your hot tap water is a brown, rusty color, you may be dealing with rust corrosion. Your water heater is made of steel. This means that over time, water will cause the tank to rust. This is why your water has something called an anode rod. The anode rod is in place as an internal rust protection element. This 3-5 foot rod rusts in place of the tank. So, once the rod deteriorates, your water heater is next. 

The solution: 

To prevent this problem, inspect the anode rod at least once every two years. You’ll probably need to change the anode rod once every 4-5 years (or sooner if you have a water softener).

Excessive Internal Pressure 

If too much pressure builds in your water heater tank, it will eventually spring a leak and burst. Luckily, the tank has something called a T&P (temperature and pressure) relief valve. The T&P relief valve is in place to release water to keep the pressure down at a safe level. However, even with the valve, the extra pressure can wear down the tank over the years. 

The solution: 

Set the temperature of your water heater to 120-125° F. Any higher than that and you will increase the pressure in the tank and your chances of getting scalded. Also make sure that you are testing the T&P valve at least twice a year to make sure it can relieve the pressure in the tank.
