How to Extend the Lifespan of Your Water Heater: 7 Maintenance Tips

Water heater care

Water heaters are a crucial part of any household, providing hot water for daily tasks such as showering, washing dishes and doing laundry. However, they are often taken for granted until they stop working or fail to produce enough hot water. To avoid unexpected cold showers and expensive repairs or replacements, it is important to regularly maintain your water heater.

In this guide, we will discuss 7 maintenance tips to help extend the lifespan of your water heater and ensure it continues to provide hot water efficiently for years to come.

Drain and Flush Your Water Heater Regularly

Over time, sediment and mineral deposits can build up in your water heater tank, reducing its efficiency and potentially causing damage. To prevent this, it is recommended to drain and flush your water heater at least once a year. This process involves turning off the power or gas supply, connecting a hose to the drain valve, and flushing out the tank until the water runs clear.

Check and Replace Anode Rod

The anode rod is a sacrificial metal rod that attracts corrosive elements in the water, protecting the tank from rust and corrosion. However, over time, the anode rod will deteriorate and need to be replaced. It is recommended to check the condition of the anode rod every 3-4 years and replace it if necessary.

Inspect for Leaks

Regularly checking for leaks around your water heater can save you from costly damages in the future. Look for any signs of water puddles, rust, or corrosion on the tank, fittings, and pipes. If you notice any leaks, it is important to address them immediately to prevent further damage.

Test Pressure Relief Valve

The pressure relief valve is an important safety feature that releases excess pressure buildup in the tank. To ensure it is functioning properly, it is recommended to test the pressure relief valve once a year. This can be done by lifting and then releasing the handle to allow some water to escape.

Insulate Your Water Heater

Insulating your water heater can help improve its efficiency and reduce energy costs by keeping the heat inside the tank. You can purchase a pre-cut insulating blanket or wrap your water heater with insulation material.

Adjust Temperature Settings

Most water heaters come with a default temperature setting of 140°F, which can be too high and lead to energy wastage. It is recommended to lower the temperature to 120°F, which is still hot enough for daily use but will also save you money on your energy bills.

Schedule Professional Maintenance

While there are many maintenance tasks that you can do yourself, it is also important to schedule regular professional maintenance for your water heater. A trained technician can thoroughly inspect and service your water heater, ensuring it is running at its best and catching any potential issues before they become major problems.


Taking proper care of your water heater through regular maintenance can help extend its lifespan and save you from unexpected breakdowns and costly repairs. By following these 7 tips, you can ensure your water heater continues to provide hot water efficiently for many years to come. Remember, prevention is always better than cure when it comes to maintaining your appliances!
