Does a Leak Spell Doom for Your Water Heater?

water-heater-in-the-cornerYour water heater is an essential home appliance, and you may not even think about it until it stops working. Water heaters need routine maintenance to stay in optimal condition. However, even with regular maintenance, there is a chance that your water heater can develop a leak

In the case of a leak, you are likely wondering what can you do, and what the consequences would be if you don’t repair it. We can provide the information on water heater leaks that you need to know here.

Causes of a Leaky Water Heater

Curious about what can cause your water heater to leak? Here are some possible problem-causers to be on the alert for:

Clogged Drain Valve

The drain valve can become blocked due to sediment build-up. If water is leaking from your water heater drain valve, then the best thing to do is call a professional. During an annual water heater tune-up, a technician ensures that the tank is clean and there is no excess dirt or sediment blocking the drain. They can quickly identify whether the drain is the source of the leak or if it stems from another part of the tank.


Hard water is common in many parts of the United States. Because hard water contains a high concentration of minerals, they can build up inside your water tank and eventually corrode its interior. Tank systems come with an anode rod to prevent this in a majority of cases. However, in an older system, there is a higher chance that your tank may become susceptible to corrosion anyway.

You can replace a corroded anode rod (that’s why it is there) but if your water heater tank itself corrodes and springs a leak, it will likely need to be replaced. Installing a home water softener and purification system can help to reduce the chances of this happening.

Old Age

Depending on the age of your water heater, a leak may be a sign that it’s time to replace your tank. The average lifespan of a water heater is approximately 12 years to 15 years.

Signs of a Water Heater Leak

In addition to visible water coming from the tank, there are other warning signs that your water heater is leaking.

  • No hot water. A complete lack of hot water is a sign that your water heater is leaking.
  • Knocking or rumbling sounds. As water heaters age, their components wear out and start to make noise when they operate.
  • Reduced output. You may notice that your hot water supply is not as strong as it once was. This may indicate a leak in the system.

Do I Need to Replace My Water Heater?

In many cases, a technician can repair your leaky water heater without replacing the tank, such as if you have a leaking pipe or worn-out connection. However, if the leak is coming from inside the tank, then the system is no longer fixable and needs to be replaced.
