A Guide to Descaling Your Water Heater

Descaling Your Water Heater


Descaling your water heater is a maintenance task that helps your water heater work better for longer. The descaling process gets rid of hard water deposits and can prevent burner problems and corrosion. It’s a relatively easy task for homeowners to complete. Here is a quick overview of how to descale the average residential water heater: 

  • Disconnect the power to the water heater
  • Turn off all the water to the appliance
  • Open all faucets in the house to release the water
  • Drain the water heater using a garden hose
  • Remove the heating element (Note: Not all water heaters have a heating element. Refer to your owner’s manual for the location of the component, if applicable)
  • Avoid chemical cleaners except those recommended by your plumber
  • Use a natural cleaning mixture of 1 part vinegar and 1 part water 
  • Use a scrub brush and the cleaning mixture to scour the inside of the tank
  • Rinse the water heater by refilling it and then letting it drain again
  • Rinse and repeat as often as needed until you don’t have any hard water particles present in the tank
