Water heater flushing is an important process that can help to extend the useful life of your heater as well as increase its energy efficiency and performance. Flushing is simply the process of emptying the tank with the aim of removing mineral deposits, which may have accumulated over time. If left unchecked, these impurities may clog the drain valve and prevent it from working. Ideally, water heaters should be flushed annually, or at least every two or three years.
Flushing Your Water Heater
Before you flush the water heater, there are two things you need to do. The first thing is to turn off the cold water supply while the second is to turn off the heating system. In case of an electric water heater, all you need to do is turn off the circuit breaker supplying power to the heater. If you have a gas heater, you can set the valve to the lowest setting possible. This safety precaution will prevent you from being electrocuted, or scolded by hot water from the heater.
The second step is to connect a garden hose to the drain valve to empty the tank. Open the drain valve and let water flow into a bucket for closer inspection. You will notice some dark particles in the bucket.
In the third step, close the drain valve and turn the cold water supply back on. Be sure to also open one or two faucets to prevent pressure buildup in the water tank as cold water comes in. Fill the tank half-way full and close the cold water supply valve. Open the drain valve once again to drain the cold water. Repeat the same procedure as many times as possible until you notice clean water coming out. Once you are done, you can restart the heater.
Restarting Your Water Heater
Step 1: Close the drain valve and remove the garden hose.
Step 2: Open the water inlet valve to its normal setting and wait for the tank to fill up.
Step 3: Open all hot water faucets until cold water starts to come out. This helps in getting rid of air from the system.
Step 4: Turn the circuit breaker back on. In case of a gas heater, adjust the gas valve to its normal setting.
