How to do a Water Heater Maintenance

Depending on what type of unit your water heater is, it might last for around 10-20 years. Even with its expected life expectancy, it might not last long enough if it’s not properly taken care of. This shows the importance of having a water heater maintenance. Read the tips below to learn more on how to properly maintain a water heater.

Setting at the Right Temperature

A lot of water heater owners tend to ignore the importance of setting an ideal temperature. The rule of thumb is to set the temperature at around 115-120°F. If you like raising the temperature above 120, you really need to adapt and cut it down to the recommended settings. You see, having an extremely high temperature can destroy the tank’s water heating system and can cause overheating.

Aside from that predicament, your electricity bills will also become higher since more energy is needed for the water heater to increase the temperature. Another important thing you should take note is that having a very low temperature is also dangerous. Why? It’s due to the fact that deadly bacteria that live in low temperature may start reproducing in your water supply.


Drain Out the Tank Every Now and Then

Take some time to flush out water out of the tank occasionally. This is to ensure that there won’t be any sediment accumulation while averting other complications such as corrosion and oxidation. Keep in mind that in order to perform a full flush, the entire heating system should be turned off. You can opt for a mini-flush as a short term solution, but it’s always better to have a full flush for better sediment removal.


Replace the Anode Rod if Needed

The anode rod is a metallic cylinder placed at the center of the water heater tank. Its main purpose is to act as a sacrificial metal that absorbs rust, which is why it’s also called sacrificial anode rod. It’s important for the anode rod to be replaced if it has outlived its usefulness since the entire tank system will be prone to rusts. A degraded anode rod is completely useless and should be replaced as soon as possible. An anode rod should be checked every one to three years. Here are some signs that an anode rod needs to be renewed: rod doesn’t have hints of silver anymore and is completely rusted, the steel wire is divulged, and that the rod is ½ inch less than its original size.


Temperature and Pressure Relief (TPR) Valve Maintenance

TPR valve is an extremely integral part of a water heater as it helps safeguard the water heater from excess water pressure and temperature. It automatically disperses water if ever the water heater is beyond its threshold limit. Now that the importance of the TPR is shed to light, it’s time to discuss how to properly maintain this important feature. To examine if there is anything wrong with the TPR, lift the lever up for around 10 seconds and let go of it. There should be a splashing sound. This indicates that the TPR valve is working, but if you can’t hear anything after doing the inspection test, there is something wrong and you should let a plumber check it.
