The build up of sediment in your water heater can cause inefficient operation and decrease the life of the heater. These easy steps will help you to drain your water heater.

Difficulty: Moderately Easy
Instructions

Things You'll Need:

  • Garden Hose
  • Bucket 5(Gallon)
  • Wrench
  1. Step 1

    Disconnect the power to the heater at the breaker or simply unplug from the wall. Connect a garden hose to the drain outlet at the base of your water heater. Extend the hose to the street or to a drain. You may also use a bucket.

  2. Step 2

    Turn off the water supply to the heater. Then begin the process by opening the drain outlet. The draining could take up to several hours to drain depending how much sediment is in the tank. Check the element to see if it is time to replace them. There are upper and lower element. Once you remove the element, go ahead and replace, it will be more cost effecient in the long run.

  3. Step 3

    Once the water coming out of the hose is down to nothing, the job of draining is complete. Remove the hose and close the drain outlet. You are now ready to refill.

Tips & Warnings
  • Release the pressure valve if there is one.
  • Use caution when working with gas water heaters.
  • Be careful when you open the drain, the water is hot.
  • Be careful not to burn yourself, the water is HOT!!!!!!!!!
