How to Extend the Lifetime of your Water Heater

Most people tend to ignore water heaters until they present serious problems and this not only disrupts the hot water supply but also leads to premature failure of their water heater.

Here are a few measures that you can take in order to extend the life of your water heater.

Test the Pressure-Relief Valve

Water heaters—both gas and electric—come with a built-in pressure-relief valves that prevent excessive pressure from building up inside of the tank. It’s extremely critical that this valve is functioning properly as too much pressure can cause an explosion.

To test whether it’s working correctly, all you need to do is simply lift the valve—typically located on the side or top of the heater. Ideally, the water should come out of the discharge pipe. If not, it’s important to get it replaced by calling a professional service provider.

Check the Anode Rod

Every water heater has an anode rod installed inside the tank to prevent rusting. The anode rode attracts rust to its surface which might otherwise have affected the tank. However, once the anode rode is completely corroded, it can no longer perform its job and the water tank can start rusting.


To prevent this, it’s important to watch for signs if you need to change the anode rod. Make sure to get the anode rod replaced on a timely basis. Typically, they can last around three years, but it’s a good practice to have it checked more often to ensure your water tank does not suffer from irreversible rusting damage.

Flush the Tank

Over time, your water heater can accumulate sediment and residue, developing a thick layer in the bottom of the tank. As a result, the unit has to work much harder and consume extra energy. Moreover, it can also lead to corrosion and rust, causing dripping and leakage issues.

Make sure to perform the water maintenance flush treatment once or twice every year to prevent the buildup of sediments in your tank. The process requires shutting off the power, carefully draining out the water of the tank, and then pouring hot water while keeping the drain valve open.

The water that comes first will be filled with gooey, filled with sediments, but after a few rounds, it will become clear. Once done with the process, fill the tank partially with cold water and drain it one more time.

Preventative Maintenance

When it comes to extending the lifetime of your water heating, there’s no substitute to regular preventative maintenance service. Aforementioned measures can certainly help you make your water heater tank last longer, but they cannot help you ensure that your water heater is in perfect working condition.

There are several issues that you’re not likely to catch, but a professional technician will be able to identify during the maintenance service. This will prevent minor problems from exacerbating and causing permanent damage to your water tank, thereby increasing the lifespan of your water heater.
