Should You Drain Your Water Heater Every Year?

Homeowners rely on hot water daily, from showering in the morning to running the dishwasher after dinner. Despite this, we rarely think about our water heaters until something goes wrong. In this article, we’ll discuss why water heater flushes and water heater maintenance are vital to the health and longevity of your home’s water heater.

How Does It Work?

Water heaters need to be flushed and drained regularly for maintenance. Water is flushed out when your water supply is turned on. Emptying a tank is the purpose of draining it. This constant flow of water flushes away sediment buildup in your tank by replacing all the water in it with new water.

To ensure the quality of your water and the state of your water as it flows through your home, you should flush and drain your water heater regularly. To remove sediment built up over time, flush and drain the water heater at least once a year. Licensed HVAC contractors from E&M HVAC in Cleveland recommend draining and flushing once every six months, even though you should do it once per year.

Should You Drain Your Water Heater Every Year?

Water heaters should be drained and flushed twice a year: once in the spring and once in the fall. Minerals and sediment are flushed out of water heaters, which is why. In addition to the natural mineral content of hard water, tap water also contains the mineral content of hard water. A certain amount of these minerals falls to the bottom of the tank and accumulates there. The bottom of a tank water heater usually has a heating element, which presents a problem. It is important to note that the more sediment and mineralization between the heating element and the water, the less efficient and effective your water heater will be.

Problems That Can Occur if You Don't Flush Your Water Heater

As sediment and minerals accumulate at the bottom of your water heater, the longer it goes without a drain-and-flush. Eventually, scaling occurs as a result. Ever notice the hard mineral buildup on your shower heads and sink faucets?

The scale consists of mineralization accumulating over time. You could start experiencing some significant problems if you have enough of that in the tank of your water heater:

  • As scaling accumulates at the bottom of the tank, your water heater will become less effective at heating water.
  • When you fail to flush your water heater regularly, you could also experience corrosion attacking the tank, weakening its structural integrity.
  • Your water heater comes with a pressure-relief valve that prevents pressure from building up inside the tank. It is possible to block this valve due to scaling.


Your water heater needs to be flushed and drained regularly. The pressure-relief valve in your water heater should also be tested every year and regularly drained and flushed. Professional plumbers can help you with cleaning tasks.
