How To Drain Your Water Heater: 4 Step Guide

Your water heater is a very valuable appliance in your home. That’s why it’s important to maintain it and drain your water heater every year, no matter what type of storage-tank you own. Over time, sediment builds up within your appliance, which compromises its energy efficiency and can lead to issues throughout your home. Avoid unnecessary issues by following these simple steps.

Step 1: Check The Pressure-Relief Valve

First, you need to check the pressure-relief valve. This valve keeps your tank from bursting due to excess pressure. To ensure that the valve is functioning properly, you must first turn off the power to the water heater — if your tank runs on electricity, simply switch it off, if it runs on gas, switch the heater to ‘pilot’ mode. 

Next, trip the lever on the valve in the cold water supply line. To minimize mess, place a bucket under your pressure-relief valve. Once you open the valve, you should hear hissing air and see the water. If you do not, then it more than likely needs to be replaced. 

Step 2: Run Your Drain Line

The next step to draining a water heater is to connect a garden hose to the water tank. Run the garden hose to the exterior of your house. Depending on where your water heater is located in your home, you may need more than one length of hose. 

To be on the safe side, give the water in the switched-off heater plenty of time to cool down before opening the drain valve — this may be a few hours. If you would like to speed up the process, you can take a long, hot shower or utilize what hot water you have left elsewhere in your home. 

Step 3: Flush Your Tank 

After opening all of the hot water faucets around your home, open the water heater drain valve. If you have chosen to use a pump, now is the time to activate it. Drain the water heater completely, then turn on the water supply in short bursts to help dislodge any sediment buildup. If needed, remove the drain valve so that sediment can exit through the opening. Keep several large buckets nearby, you may need them for this process!

Step 4: Finish Draining

Once the water draining from your water heater appears to be running clear and free of sediment, turn off the supply again. Next, close the water heater drain valve and turn on the cold water supply. At this time, you will want to return the pressure-relief valve to its initial position. You can also turn off all of the faucets around your home that were activated on during Step 3. Finally, you can restore power to your water heater.
