Greetings, fellow homeowners! If you’re looking to maintain your electric water heater and increase its lifespan, one essential task you should add to your to-do list is draining it. Draining your electric water heater can help get rid of sediment build-up, improve performance, and prevent costly repairs. However, if you’re unsure how to do it, don’t worry. In this article, we’ll go over all the steps you need to follow to drain your electric water heater successfully.
First and foremost, let’s go over the basics of an electric water heater. It consists of a tank where the water is heated and maintained at a chosen temperature. The heating element is powered by electricity and can be either 120 or 240 volts, depending on the model. When sediment builds up at the bottom of the tank, it can cause corrosion, decrease efficiency, and lead to malfunctions. Therefore, it’s crucial to flush out the tank and get rid of the sediment every year or so, depending on usage, to prevent these issues.
Now that we’ve covered the importance of draining your electric water heater, let’s move on to the actual process.
How to Drain Your Electric Water Heater: Step-by-Step Guide
Step 1: Turn off the Power
The first thing you need to do before draining your electric water heater is to turn off the power supply. This is not only important for your safety but also to avoid damaging the heating elements. You can turn off the power by either flipping the breaker switch or turning off the on/off switch located near the water heater. Make sure no one turns the power back on until you’ve finished draining the tank.
Step 2: Turn off the Cold Water Supply
Next, you need to turn off the cold water supply that feeds into the tank. This will prevent more water from entering the tank while you’re draining it. Locate the shut-off valve, which is usually located near the water heater, and turn it off by turning the handle clockwise.
Step 3: Open a Faucet
After you’ve turned off the cold water supply, it’s time to open a faucet in your house to relieve any pressure in the system. Choose a hot water faucet and leave it open until the water stops running. This will ensure that no more water enters the tank while you’re draining it and make the process smoother.
Step 4: Connect a Hose to the Drain Valve
Now it’s time to connect a hose to the drain valve at the bottom of the tank. You’ll need a garden hose or a hose specifically designed for draining water heaters. Attach one end of the hose to the drain valve and the other end to a suitable drain location, such as a floor drain or outside your house. Make sure the hose is tightly secured to prevent leaks.
Step 5: Open the Drain Valve
Once the hose is securely attached, it’s time to open the drain valve. To do this, turn the valve handle counterclockwise and let the water flow through the hose. Be patient, as the draining process can take anywhere from 20 minutes to an hour, depending on how much sediment has accumulated.
Step 6: Flush the Tank
After the water has drained out, you can flush the tank with cold water to get rid of any remaining sediment. To do this, turn on the cold water supply and let it flow into the tank for a few minutes. Turn off the cold water supply and let the tank drain again through the hose. Repeat this process until the water runs clear and free of sediment.
Step 7: Close the Drain Valve and Faucet
Once the water runs clear, it’s time to close the drain valve and the faucet you opened earlier. Turn the drain valve handle clockwise to close it and detach the hose. Make sure to drain any remaining water left in the hose outside or in a suitable drain. Close the faucet you opened earlier and turn on the cold water supply to fill the tank back up.
Advantages and Disadvantages of Draining Your Electric Water Heater
Draining your electric water heater has several benefits that make it worth the effort. Here are some of the advantages of draining your electric water heater:
1. Improved Performance
By getting rid of sediment and mineral buildup, you can improve the efficiency of your electric water heater. This means it will take less time to heat water, and you may see a reduction in your energy bills.
2. Extended Lifespan
Draining your electric water heater can help prevent corrosion and other damage caused by sediment buildup, which can ultimately extend its lifespan.
3. Reduced Risk of Repairs
By flushing out the sediment, you can prevent potential malfunctions and repairs, saving you money in the long run.
