The following info was brought to you by http://www.bondi-plumber.com.au/ Here are the steps you can take to drain a water heater:
• Check pressure relief valve
• Run drain line
• Flush tank
• Check to see if water is clear
Checking the Pressure Relief Valve
You should always check the pressure relief valve before you drain your water heater. This valve tells you how much pressure is in the tank. The water heater needs to be switched off. If it operates off of electricity, turn the unit off. Some water heaters burn gas. These types of water heaters need to be switched to pilot mode. After that, trip the lever on the valve in the cold water supply line. You should get a bucket to put under the pressure relief valve. When the valve is open, you need to listen for air as well as look for water. If you hear or see either, it means the valve is working properly. You can go to the next step after that. However, if nothing happens at all, then it may need to be replaced.
Running Your Drain Line
If you have a garden hose, run it from the water heater to the outside of your home. You will need at least two lengths if your water heater is in the basement. One hose should from run the tank to a portable pump. The other hose should run from the pump to the outside. Gravity should help if your water heater is located anywhere else. The water in the switched off heater needs a lot of time to cool down. You should give it about several hours to cool down to be on the safe side before the opening the drain valve. A long, hot shower will speed up this part of the draining process.
How to Flush Your Tank
The water heater drain valve should be opened after you open all of the hot water faucets around your house. If you have a pump, now is the time to activate it. Turn on the water supply after you have drained the water heater completely. Short bursts of water may help dislodge any sediment buildup. You may want to get out of the way if any sediment obstructs or slows the flow of water from the drain valve. The drain valve should be removed so that the sediment can exit through a bigger opening. You can use a dowel or a long screwdriver to help you dislodge any sediment after the valve has been removed. You should keep a few large buckets on hand to capture the outflow as well.
Making Sure The Water Is Clean
Once the water seems to be running clear, you can turn off the supply again. After that, close the water heater drain valve and turn the cold water supply back on. The pressure relief valve needs to be returned to its initial position. Then, the hot water faucets that were turned on earlier need to be shut off around the house. Finally, you can restore the power to your water heater. It should be free of any sediment.
