Water heaters are essential appliances in our homes and businesses. They provide hot water for cooking, cleaning, bathing and other important household chores. As important as they are, they are often overlooked when it comes to maintenance, and as a result, they break down unexpectedly and require costly repairs. This blog post will offer proactive tips on how to maintain your water heater to ensure it has a long lifespan and continues to function efficiently.

Regular Flushing

The accumulation of sediment and mineral buildup is one of the main reasons for the premature failure of a water heater. Flushing your water heater at least once a year can help prevent mineral buildup and sediment, thus improving the efficiency of the water heater. Drain the tank until the water runs clear, and then refill the tank.

Check for Leaks

Water leaks can cause significant damage to your home and increases your utility bills. Checking for leaks regularly can help prevent these issues. Check for any leaks on the top, bottom or sides of the tank. Leaks can be caused by a faulty drain valve, pressure relief valve, heating elements, and tank itself.

Test the TPRV Valve

The temperature, pressure relief valve (TPRV) is an essential safety valve that helps to regulate the temperature and pressure inside your water heater tank. Testing the TPRV valve annually can help to ensure that it is functioning correctly, preventing any accidents from happening.

Inspect the Anode Rod

The anode rod is a critical component of your water heater that prevents the tank from rusting. Over time, the anode rod corrodes, and if not replaced, the tank can rust and fail prematurely. Inspect the anode rod annually and replace it if it shows sign of significant corrosion.

Maintain the Temperature Setting

Setting a temperature that is too high can cause the water heater to work harder, thus increasing your energy bills. Conversely, setting the temperature too low can cause bacteria to grow, resulting in poor quality water. Maintaining the temperature between 120 to 140 degrees Fahrenheit is recommended.


Taking care of your water heater regularly cannot only extend the lifespan of the appliance but also save money in the long run. By following these proactive tips, you can help prevent any unexpected breakdowns, leaks, and repairs. Don’t neglect your water heater; invest a little time in maintenance to ensure a long lifespan, efficient performance, and a steady supply of hot water.
