How Often Should You Flush Your Hot Water Heater

116

To ensure the longevity of your water heater, you need to occasionally drain it and clear it of sediment. Those two things will help boost the appliance’s efficacy as well as minimize damage to the unit. With that, you might be wondering, how often should you flush your water heater?

Check your manufacturer’s instructions

This is because the frequency of flushing your water heater will generally depend on the size of its tank as well as the amount of hot water used.

Now, if you can’t access the manufacturer’s instructions, you can consider the following rules:

  • If there are only 1 or 2 people at home, inspect the unit and drain it every year
  • If there are about 3 to 5 people in your home, do it every 8 months.
  • For a home with 6 or more people, it’s good to check the water heater and drain the appliance every 6 months.

It may take a while for you to actually notice the accumulation of sediments in your tank. Usually, it becomes noticeable when less and less water comes out from the tank and you see the sediment coming out of it.

If you’ve drained your tank and you’re still not seeing an improvement, you may want to get it checked by a professional. Apart from sediments, you may also want to check it for noise.
