If you want to make your water system more efficient and save more money, it’s important to flush your tank at the recommended time.

Even though it is called “Hard Water”, it doesn’t mean that hard water will dent your tank. Hard water is a water source that has a high mineral content, mainly calcium and magnesium ions. A lot of households use a water softener to transform calcium and magnesium ions into something else by using salt.

Water gets a high amount of calcium and magnesium ions when there are a lot of mineral deposits in the area. The water gets these minerals during the water cycle, where the rain falls into the ground and makes its way on underground water deposits or at the surface. This is not harmful to humans, but it is harmful to plumbing systems because it causes scalings or sediments that disrupts the efficiency of the system.


How Can Hard Water Affect Your Heater Tank?

This Water can cause scale buildup which clogs the pipes and eventually cause a problem to the water heater if left unnoticed. Although filters can help in reducing scale build-up, these filters will eventually run out of efficiency, which can cause problems if left alone for a long time. If the sediments are not cleaned, it can reduce the efficiency of your water heater tank.

When sediments reached the hot water heater system, these objects will settle down at the bottom of the tank. You wouldn’t notice it at first, but as time goes by, these sediments will form at the bottom. Soon, you will get less hot water because of the accumulated sediments. Additionally, you will also have to pay additional money because your system needs more power to make the water flow.

It’s easy and there’s really no reason to omit this activity each year.

Easy Way To Drain Your Water Heater Tank

1. Preparations

The first step in draining your water heater tank is to make sure that the main supply line is turned off or disconnected. This step is to make sure that no new water will be flowing inside the tank. Make sure that the water heater itself is turned off, which can be done by shutting down the electric circuit to the heater or bringing the gas line to the “pilot” mode. Connect your hose to your drain valve.

2. Drain Valve And Pressure Relief Valve

Next, release the Drain Valve to start the draining process. This can be done by loosening the valve that can usually be found where you attached your hose. If you have a valve opener, use it to open the valve for your system. Take note that to drain the water, you need to open the pressure relief valve which is usually found on the top of the water tank.

3. Let It Drain

Once the pressure relief valve has been opened, the water will start to drain. The water will be very hot, so be cautious and avoid contact with the water. Get a container or a bucket that you can use to catch the draining water. If you see any discoloration in the draining water, it might be a sign to look for another water heater.

4. Final Steps

After all the water was a drain, close the pressure relief valve to stop the air intake. Connect or open your main supply line to wash out all the other deposits remaining in the water tank. Finally, turn on the power to your water heater and test your water faucets.


Flushing your water heater is a very easy maintenance step that every homeowner must know to prevent the damages from water. If you’re having a hard time or are inexperienced when it comes to plumbing, better call a professional to help you. I hope you learned something useful from this article.
