How Do You Drain A Hot Water Heater

Why You Should Drain and Refill Your Hot Water Heater

Hot water heaters are designed to last up to 12 years, which is a significant improvement on the lifespan of their predecessors. However, with regular maintenance, you can expect to get a lot more out of your investment. Draining and refilling your hot water heater every two to five years will extend its lifespan significantly. In fact, it’s estimated that doing this will add about 10 years to the life of your tank. Hot water heaters are made of metals, such as copper and stainless steel, that are susceptible to rust. Sediment from your water supply will build up inside the tank, which will increase the likelihood of rusting. When that happens, you’ll either need to replace the tank or clean it out. Cleaning it isn’t as effective, and it carries a higher risk of injury. Therefore, it’s better to drain the tank and avoid the problem altogether.

Step 1: Turn Off the Electricity

Before you do anything else, shut off the electricity to your water heater. You don’t want to be standing in water while managing the other aspects of this job. You can shut off the electricity by shutting off the main circuit breaker in your home.

Step 2: Drain the Tank

If your water heater has a drain valve, open it to begin the draining process. If your water heater doesn’t have a drain valve, you can complete this section using a sump pump or a bucket of water. For the latter, put the bucket under the water heater and let it fill up until it starts to flow out of the water heater. Once the water begins to flow, use a bucket or sump pump to remove it.

Step 3: Disconnect the Drainpipe

If your water heater has a drainpipe, you need to disconnect it to ensure that the water can flow freely. You can do this by opening the clamp at the top of the drainpipe and pulling it down and away from the water heater.

Step 4: Flush Out the Sediment

Once you’ve removed the water from the tank, you’ll be able to see the sediment that has accumulated. You can either use a garden hose or a water hose to flush it out of the tank. Use enough water to remove all of the sediment, but don’t use so much water that it flows back into the water heater.

Step 5: Refill the Tank

The next step is to refill the water heater with clean water. You can buy a water test kit to determine the quality of your local water supply, or you can use a water hardness test kit to determine the level of minerals in your water. With this information, you can choose the correct water softener to use with your water heater. Once you’ve done this, fill up the water heater until it reaches the top.

Step 6: Test your hot water heater

At this point, you’ve drained and refilled your water heater and flushed out the sediment that has accumulated. So now it’s time to test it to see if it works properly. Turn the electricity back on and let the water heater tank heat up, just like you would if you were going to use it. While you’re waiting, use a water quality test kit to determine the quality of your water supply. Once the tank has heated up, test the water from every faucet in your home. It should be hot, clean and safe to drink.

One of the most important maintenance tasks for a hot water heater is draining it regularly to remove any sediment that has built up. Over time, this sediment can cause the heater to become less efficient and even break down completely. Draining the heater is a simple process, but it’s important to do it correctly to avoid any damage. The first step is to turn off the power to the heater. Next, locate the drain valve and open it to allow the water to start draining. Once the water has stopped draining, close the valve and turn the power back on. That’s all there is to it! By draining your hot water heater regularly, you can extend its lifespan and keep it running efficiently for years to come.
