Why Should You Flush Your Water Heater Every Year

Your hot water heater is one of the many things that you probably forget about until it doesn’t work. After it’s installed and set to the right settings, it’s easy to keep it out of sight, out of mind, as long as it does its job for years. 

However, like your car or any other equipment in your home, your hot water system requires your attention, too. In specific, you should flush it at least every year. Plumbers also recommend that you engage hot water system replacement services after your unit is past its useful life. 

Why should you do it, anyway? Find out in this article.

Here’s Why It’s Important to Flush Your Water Heater

All water has mineral content to some degree. But, it is higher in areas with more limestone underground, where the groundwater picks up calcium and magnesium deposits that result in hard water. This hard water creates sediment that settles at the bottom of the water, acting as an insulator that keeps the water from getting warm. 

When left unaddressed, the sediment can harden, making it difficult to remove. In worse cases, it can clog the drain valves as well, requiring you to replace the unit. These consequences illustrate the necessity to flush your hot water tanks regularly to prevent it from causing further problems down the line. 

Is There Sediment Buildup in Your Water Heater?

You would know that a significant amount of sediment is building up in your water tank when you start to experience the following issues: 

  • Your water is taking too long to heat – The sediment covers the heating element which is generally located at the bottom, thus keeping it from warming the water. 
  • Fluctuating water temperatures – With natural gas heaters, the sediment usually causes uneven heating. Over time, this may even cause a pipe burst or premature failure. 
  • Unusually high energy bills – As the buildup becomes more severe, it may force the water heater to work harder and this reflects in your utility bills. 
  • Lower supply of hot water – Aside from uneven heating, the sediment buildup can also affect the unit’s energy efficiency and ability to maintain a consistent hot water supply. 
  • Rumbling or popping sounds – What you’re hearing is water trapped underneath the sediment buildup and is boiling. 

How to Flush Your Water Heater

How to Flush Your Water Heater

Ask any local plumber and they would recommend you to flush your hot water tank once every year. This is a good preventive measure to prolong the life of your heater and avoid unnecessary damage in the future. 

For your safety and to guarantee the success of the job, it’s better to hire a plumber to flush your tank. During the process, your plumber will turn off the water supply and dump the water out to empty the tank.

Afterwards, they will turn on the water supply, flushing out the water. This constant flow of new water should wash away the sediment buildup in the tank. You would know it’s complete when the water already runs clear.  

Leaving sediment build up in your tank can not only force it to work harder but also lead to some serious issues. Over the course of two to five years, the buildup could be enough to cause pipe bursting, loss of water pressure, or even a total breakdown. 

Therefore, while it’s time-consuming and seemingly costly, flushing your water heater can benefit you in more ways than you can imagine. Keep in mind that it’s more expensive to have a full hot water tank replacement than to just flush it out every year. 

When in doubt, a plumbing contractor with years of experience is just a call away. You never know there might be other plumbing issues that are indirectly related to your water heater system. A licensed plumber can trace the problem and provide the best solutions.

For instance, only an expert plumber for pipe relining Sydney services can help you save hundreds of dollars when it comes to blocked pipes. Note that there are various fields related to plumbing so hiring a professional is highly recommended.
