How To Flush Water Heater

Flushing Water Heater For Dallas Homeowners

You can enhance the efficiency and prolong the life of your water heater by flushing it out. This is especially important if you do not have a water filter on the incoming line of your water supply to your house. Any sediment in the cold water entering the water heater will fall to the bottom of the water heater because it is heavier than the water.

Flushing Your Water Heater is very important for your water heater.

How to Flush a Water Heater

Have you flushed your water heater lately? This boring but important chore should be done at least once a year to remove sediment that accumulates on the bottom of the tank. That’s especially true if you live in a hard-water area. The task is easy to blow off because it’s out of sight—but skipping it is costing you a lot. Sediment buildup reduces the heating efficiency of your water heater.

Step 1. If you have an electric water heater, turn the electrical power to the water heater off at the breaker box. If you have a gas water heater, turn the thermostat to the vacation mode setting or the lowest setting possible without actually turning off the pilot light.

Step 2. Allow the water heater to cool. This can be done by waiting for the heater to cool down for a few hours or someone could take a shower, do laundry, or wash some dishes at this time causing all the hot water to be used up (after, all you already paid to heat it!) and replaced by cold water.

Step 3. Turn the cold water supply to the water heater off – this valve is normally located at the top of the water heater on the INLET side.

Step 4. Connect a garden hose to the drain outlet valve at the bottom of the water heater but do not open the drain valve just yet. Place the other end of the garden hose in a convenient drain location or someplace outside like onto your lawn or garden area. Note that the hose outlet must remain lower than the water level in the tank in order for the water to drain completely out of the water heater.

If you choose to not wait for the water heater to cool, then make sure you use a hose that can withstand hot water. The other end of the hose should be placed where hot water will not harm anything, like children, pets, plants or shrubs, and remember the hose and hose outlet may be too hot to handle with your bare hands.

You can also use a water heater drain pump to speed up the process. Depending on which water heater drain pump you use you can empty a 50-gallon water heater tank within 2-1/2 to 10 minutes instead of waiting for the water heater to drain by gravity.

Step 5. Open the hot water side of your kitchen faucet (or the hot side of any faucet close to your water heater). This will allow air to flow back to the water heater stopping any vacuum in the water heater that will keep the water from flowing out of the drain.

Step 6. Now go back to the water heater drain valve and open it slowly until it is fully open. If you are using a water heater drain pump, turn the pump on after you have opened the drain valve. As the water flows out of the water heater you can let it drain into a clean bucket to see how much sediment is being flushed out. This can help you determine how often you may (or may not) need to flush your system, and also whether or not you might want to consider installing a filtering system.

Step 7. Once the water heater is drained, turn the pump off, if using a pump, and close the drain valve. Open the cold water supply at the top of the water heater and let the water run for 5 to 10 minutes. This can help to dislodge more sediment that may still be in the bottom of the water heater.

Step 8. Turn off the cold water supply at the top of the water heater and again open the drain valve (turn the pump on again if the pump is used) and let this water drain out of the tank. Examine the drain water to see if there is still sediment in the drain water or if it is clear. If the water still has some sediment in it then repeat Steps 7 and 8 until the drain water runs clear of any debris. Read more.

Importance Of Flushing Water Heater

Sediment from your water collects in the water heater and settles to the bottom of the tank. This is especially true if you have hard water. Calcium and magnesium, two common elements found in hard water, also bind together to form scale, which is a sticky, white substance that can clog pipes and line the inside of your water heater.
