Water Heater Care: Top Tips for Peak Performance

A reliable supply of hot water is an essential aspect of our daily lives. Whether it’s for bathing, cleaning, or cooking, a properly functioning water heater is crucial. However, like any other home appliance, water heaters require regular maintenance to ensure optimal performance and longevity. In this blog, we will explore the importance of water heater maintenance and provide you with practical tips to keep your unit in top shape.

Flush Out Sediment Regularly:

Over time, sediments such as minerals and debris can accumulate at the bottom of your water heater tank. This sediment buildup can cause corrosion, reduce heating efficiency, and ultimately shorten the lifespan of your unit. To prevent these issues, it is recommended to flush out the sediment at least once a year. Here’s how you can do it:

  1. Turn off the power supply or gas valve to the water heater.
  2. Attach a hose to the drain valve at the bottom of the tank and place the other end in a suitable drainage area.
  3. Open the drain valve, allowing the water to flow out along with the sediment.
  4. Close the drain valve and refill the tank once the water runs clear.

Test the Pressure Relief Valve:

The pressure relief valve is a crucial safety component in your water heater. It helps release excess pressure to prevent tank ruptures or explosions. To ensure its proper functionality, follow these steps:

  1. Turn off the power supply or gas valve to the water heater.
  2. Locate the pressure relief valve, typically positioned on the side or top of the tank.
  3. Place a bucket beneath the valve to catch any water that might be discharged.
  4. Lift the valve’s lever for a few seconds to allow water to flow out. If water doesn’t flow or it continues to drip after releasing the lever, it may be a sign of a faulty valve that needs replacement.

Check the Anode Rod:

The anode rod plays a vital role in preventing corrosion inside the water heater tank. It attracts corrosive elements, sacrificing itself to protect the tank. Checking and replacing the anode rod periodically can extend the lifespan of your water heater. Here’s what you need to do:

  1. Turn off the power supply or gas valve to the water heater.
  2. Locate the anode rod access point on top of the tank.
  3. Unscrew the hex head or use a socket wrench to remove the anode rod.
  4. Inspect the rod for excessive corrosion or depletion. If more than six inches of the core wire is exposed or the rod is heavily deteriorated, it’s time for a replacement.

Insulate the Tank and Pipes:

Insulating your water heater and pipes can help conserve energy and minimize heat loss. This is especially beneficial if your unit is located in an unheated area such as a basement or garage. Follow these steps to insulate your system:

  1. For the tank: Wrap the tank with an insulation blanket designed for water heaters, ensuring you don’t cover the thermostat or any safety labels.
  2. For the pipes: Use foam pipe insulation sleeves to cover exposed hot water pipes, paying extra attention to areas where pipes are near cold surfaces.

Inspect for Leaks:

Regularly inspecting your water heater for any signs of leaks is crucial. Even a small leak can lead to significant water damage and energy wastage. Check for water puddles or moisture around the base of the unit, near connections, or on the floor. If you notice any leaks, promptly address them by tightening loose connections or replacing faulty valves or fittings. For major leaks, it’s recommended to contact a professional plumber.

Maintain Adequate Clearance:

Proper clearance around your water heater is essential for ventilation and safety. Ensure that there is enough space around the unit for proper airflow, as specified in the manufacturer’s guidelines. Remove any debris, clutter, or flammable materials that might obstruct the area around the water heater. Adequate clearance reduces the risk of overheating and allows for easier access during maintenance tasks.

Check the Temperature Setting:

Monitoring and adjusting the temperature setting of your water heater can have a significant impact on energy efficiency and safety. The ideal temperature is typically set at 120 degrees Fahrenheit (49 degrees Celsius) to prevent scalding while ensuring sufficient hot water. Higher temperatures can not only waste energy but also increase the risk of burns. Consult your water heater’s manual for instructions on adjusting the temperature setting and consider installing a programmable thermostat for better control.

Regularly Test the Heating Elements (Electric Water Heaters):

If you have an electric water heater, the heating elements are responsible for heating the water. Over time, these elements can accumulate sediment or become faulty, leading to reduced heating efficiency or no hot water at all. To test the heating elements:

  1. Turn off the power supply to the water heater.
  2. Locate the access panel on the front of the unit and remove it.
  3. Use a multimeter to check the resistance of each heating element.
  4. If the resistance reading is significantly higher or infinite, the element is likely faulty and requires replacement.

Schedule Professional Maintenance:

While performing routine maintenance tasks on your water heater is essential, it’s also beneficial to schedule professional maintenance at least once a year. A professional plumber can conduct a comprehensive inspection, perform thorough cleaning, and address any potential issues that may not be apparent to the homeowner. Professional maintenance helps identify and resolve problems early on, prolonging the lifespan of your water heater and ensuring its optimal performance.


By performing regular maintenance on your water heater, you can extend its lifespan, improve energy efficiency, and ensure a steady supply of hot water for your household needs. Remember to consult your water heater’s manual and follow safety guidelines throughout the process. With proper care and attention, you can keep your water heater in top shape and enjoy reliable hot water for years to come.
