How to Maintain Your Water Heater


Your water heater plays a crucial role in providing hot water for various household activities, from showers to dishwashing. Neglecting its maintenance can lead to inefficiency, increased energy costs, and even a shortened lifespan. In this guide, we will walk you through essential steps on how to maintain your water heater to ensure it continues to function efficiently.

1. Regular Inspections

Start by visually inspecting your water heater at least once a month. Look for any signs of leaks, corrosion, or rust around the tank. Check the pressure relief valve and ensure it’s functioning correctly. If you notice any issues during this inspection, it’s essential to address them promptly to prevent further damage.

2. Flushing the Tank

Over time, sediment can accumulate at the bottom of your water heater tank, reducing its efficiency. Flushing the tank annually helps remove these sediments, allowing your heater to operate more effectively. To do this, turn off the power supply and connect a garden hose to the drain valve. Open the valve, letting the water flush out until it runs clear.

3. Adjusting the Temperature

Check the temperature setting on your water heater regularly. The recommended temperature is around 120 degrees Fahrenheit (49 degrees Celsius) to prevent scalding and save energy. Adjust the thermostat if necessary, but be cautious not to set it too high, as it can lead to increased energy consumption and potential safety hazards.

4. Testing the Pressure Relief Valve

The pressure relief valve is a crucial safety component of your water heater. To ensure it’s working correctly, follow these steps:

  1. Turn off the power supply to the heater. b. Position a bucket under the valve. c. Lift the valve’s tab to allow some water to discharge into the bucket. d. If no water comes out or it continues to leak, you may need to replace the valve.

5. Insulating the Tank

Insulating your water heater tank can help conserve energy by minimising heat loss. You can purchase an insulating blanket designed for water heaters at most hardware stores. Be sure to follow the manufacturer’s instructions and avoid covering the thermostat.

6. Checking for Leaks

Regularly inspect all connections and pipes for any signs of leaks. A small leak may seem inconsequential, but it can lead to water damage and mold growth over time. If you find any leaks, tighten the connections or replace faulty components promptly.

7. Professional Maintenance

While some maintenance tasks can be done by homeowners, it’s advisable to schedule professional maintenance at least once a year. A certified technician can inspect and service your water heater, ensuring it operates efficiently and identifying potential issues before they become major problems.


Proper water heater maintenance is essential for ensuring its longevity, efficiency, and safety. By incorporating these simple yet effective practices into your routine, you can enjoy reliable hot water supply while minimising energy costs and the risk of unexpected breakdowns. Regular inspections, flushing the tank, adjusting the temperature, testing safety features, insulating the tank, and addressing leaks are all part of a comprehensive maintenance plan. Remember, a well-maintained water heater not only saves you money but also contributes to a more sustainable and energy-efficient home.
