Water heater repair and installation is one of our specialties at KT Plumbing. To extend the life of your water heater it is important to conduct routine maintenance. One of those maintenance steps is to occasionally flush your water heater. It is easy to flush your water heater and does not require a service call to a plumber. The reason you want to flush your water heater is due to the buildup of sediment over time in your water heater. This buildup could eventually cause your drain valve to stop working. In addition you may also experienc3e discoloration or rusting of your water taps due to build up of calcium, magnesium, and iron.
Here are the steps to properly flush your hot water tank
- The first thing you need to do is turn off the power if your tank is electric. If it is a gas water heater make sure to turn the gas down as low as it will go.
- The next step is to shut off the cold water supply. The valve for this is usually located near the top of the water heater.
- Then attach a garden hose to the water heater drain at the bottom of the water heater.
- Open all hot water faucets in your house. This will enable the tank to drain faster.
- Open the drain valve on the hot water heater and let it drain completely. The time it takes to drain will vary based on the amount of sediment in the tank.
- Once the water heater has drained completely , close the valve and open the cold water supply at the top of the tank. Once the tank is about half way full turn off the cold water supply. Repeat Step 5 until the water is clear.
- Once the water is clear you can turn on the cold water valve and fill the tank all the way.
- To get any air out of the system open all of the hot water faucets in your home.
- Finally if your water heater is electric turn the power to it back on. If it is gas turn the gas back up to it’s original position.
Just by doing this simple process you have extended the life of your water heater by years and also made it more efficient. You should flush your water heater about every 3 years or so.
