When your water heater breaks or runs out of hot water too often, it can be frustrating. Maybe it’s an old model that no longer meets modern building codes, or maybe you have a family of six and want to limit how often you have to run the faucet to keep water flowing. Whatever the situation may be, it’s important to know how to maintain your water heater yourself so you can fix the problem before it becomes a much larger issue. There are many things you can do to keep your water heater in good working condition and prevent it from breaking down completely. Here are some ideas you may want to consider so you can avoid calling a plumber in the near future and save yourself some money on water bills. Maintaining your water heater doesn’t have to be complicated or time-consuming. With a little know-how and the right tools, you can perform most tasks yourself in just a few hours. Whether you want to tackle all of these tasks or just one, the tips listed below will help you get the most out of your time and effort when maintaining your water heater as a homeowner.

Change the water heater’s anode rod and water-pipe anode every few years.

The anode rod and water-pipe anode are two different parts of your water heater that are designed to protect the internal components from corrosion. An anode is a negatively charged metal rod that traps positive ions in the water, protecting the rest of the system from corrosion. The water-pipe anode is a flexible rubber pipe that is installed inside the water-pipe, which traps positive ions as well. The combination of the anode rod and water-pipe anode helps protect your water heater against corrosion, which is one of the most common causes of water-heater breakdowns.

Check the pilot light to make sure it’s burning.

If your water-heater’s pilot light won’t stay lit, it’s time to get it repaired. If the pilot light won’t stay lit, it means there’s a problem with the gas supply, which means you’ll need to call a plumber to come out and repair or replace the gas line. When you turn on the water-heater, the pilot light is what burns first to heat the water in the tank and allow it to flow through the rest of the system. If the pilot light won’t light, you’ll have to wait until the water in the tank reaches the proper temperature before your water comes out of your faucets.

Clean the inside of your water-heater with baking soda and vinegar.

If you have stubborn stains or scummy build-up inside your water-heater, baking soda and vinegar can help to clean the inside without a lot of scrubbing. You can also run a hose through the inside of the water-heater, spraying vinegar on the walls and baking soda on the bottom to create an abrasive cleaning solution. These two products can loosen up dirt and grime that would otherwise be very difficult to remove without specialized tools and chemicals.

Check the thermostat to make sure it’s set properly.

It’s important to make sure the thermostat for your water-heater is set properly. If it’s set too high, you’ll waste energy, which can drive up your water bill. On the other hand, if the thermostat is set too low, your water will run cold and you’ll be out of hot water much sooner. To set the thermostat, you’ll need to turn off the power to the water-heater, and then use a wrench to remove the cover on the thermostat. You should then adjust the thermostat to the desired temperature.

Change the water-heater’s anode when you change your water filter.

Depending on how long your water-heater has been in use, you may need to replace the anode in your water-heater. The water-heater anode protects the water-heater from corrosion, which is why it’s installed in the first place. If you change your water filter, you may also need to change your water-heater’s anode. While you’re at it, you may also want to clean out the inside of the water-heater, removing any build-up or residue that could be causing issues with the water flow.

Check the pressure relief valve when you clean the tank.

The pressure relief valve is there to protect your water-heater from being overfilled with water. If the tank is full and the water pressure is too high, the pressure relief valve will let excess water out of the tank. Depending on the kind of water-heater and where you live, there may be a limit to how full the tank can be before the pressure relief valve opens. When you clean the tank, you may also want to clean out the pressure relief valve, removing any build-up or residue that could be causing issues with the water flow.

Conclusion

Keeping your water-heater in good working order is essential to having reliable hot water at all times. There are many different maintenance tasks you can perform yourself to check on your water-heater and make sure it’s running smoothly and efficiently. It will save you time, money, and hassle in the long run if you can perform these tasks yourself instead of waiting on a plumber to come out and fix it.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.
  • Your older water heater is getting up there in age
  • It's making strange noises
  • You're getting rusty water out of the tap
  • Your hot water doesn't last as long as it used to
  • There are water puddles around the unit
120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
Sediment buildup shortens the life of your water heater and adds to your energy bill by reducing its efficiency. Draining two or three gallons of water is usually enough to flush out sediments, but always let the water flow until you no longer see particles in the bucket. Regular water heater maintenance will always extend its lifespan.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.
  • You're overusing hot water.
  • The water heater tank size is too small for your household.
  • Your hot water heater is tankless.
  • Sediment or minerals have built up in your water heating system.
Soft water can actually corrode the water heater anode faster. When the anode wears down, the corrosive elements will move on to the tank. So if left alone, a water softener system can actually shorten the lifespan of a water heater.
