How to Remove Calcium Buildup In Water Heater

Are you looking for how to remove calcium buildup in water heater? We have created an ultimate guide about the ways to remove calcium buildup from water.

Because calcium is a naturally occurring component of water, Water heaters and plumbing systems, in general, are susceptible to premature deterioration because of calcium buildup.

The majority of the water comes from the ground. Depending on the condition of the ground, the water may accumulate significant amounts of calcium.

So now let’s jump to know more about its demerits and procedures to remove them.

What Causes the Calcium Buildup?

Calcium deposits are to form in a hot water heater’s system due to calcium carbonate which is a mineral that can be present in water. When they begin to fall to the bottom of the tank, this mineral buildup will be there for you to find when they start to precipitate.

The problem of sediment buildup is not something that the water heater can control on its own. The dip tube, which is also known as the cold water entry pipe, is typically a straight pipe. When the water hits the bottom of the water heater, it causes the silt to settle into an even layer.

Why Is Calcium Buildup a Bad Thing?

Calcium buildup, often known as limescale, is one of the leading contributors to water heater breakdowns. The formation of an insulating layer between the gas burner and the liquid is one of the most significant drawbacks of calcium buildup. The base of the tank is what is overheating, and it has a slit in it that allows heat to gently exchange.

Limescale has calcium carbonate combined with a variety of other minerals. Over time, these deposits will develop on the floor of the water heater, on the heating elements, and on the anode rod. This will result in a decreased capacity for heating and potential safety issues.

As the temperature rises, the crystal coating will crack and the steel will become more brittle. Because this then covers the component that is underneath it and causes it to sink down. The tank’s expiry might decrease as a result.

How Can Calcium Buildups Be Removed?

Calcium buildup can be a problem for you. To get rid of those annoying calcium buildup, you can use a combination of baking soda, white vinegar, and even a lemon. Vinegar is already used by a lot of people who are responsible for cleaning their homes. Additionally, it is useful for removing the stains caused by hard water as well as calcium buildup.

To moisten the area, you can use a spray bottle or a cloth that is dampened with vinegar. For a nicer and cleaner faucet overall, you can also use an old toothbrush to scrub in areas that are difficult to access.

Follow the below steps to learn how to remove calcium buildup.

Step 1: Inspection of Water Heater.

Examine the apparatus to see if it has become contaminated with silt or calcium. After that, turn off the machine and cut off the flow of high-quality water. Establish a connection between the water line and the drain faucet. Keep the remaining portion of the hose, but store it some distance away in a drain faucet. The heat will be able to safely escape in this manner.

As you open the drain faucet, be on the lookout for any white specks, no matter how big or small. Keep an eye out for the calcium as it builds up in this area. Take off the pipe that goes into the cold water just above the heater so that air can enter the water tank. After you have finished emptying the reservoir, make sure the drain gets closed.

Step 2: Use of Various Acids and Vinegar.

Put into a single cup a bottle containing vinegar, an acidic tub, a chemical lime cleanser, and a tile cleaning solution. The bottle should be full to the brim. You should put a halt to it after each cup. Make sure you don’t get bloated as soon as you stop drinking. After a period of many hours, the storage unit should be empty. Clean to eliminate most of the sediment. A Ziploc baggie that binds snugly through an ice-water input line can be a great help in this regard.

After that, check to see if the cleaning is still effective. Continue to wait in order to determine whether or not the balloon is growing. This is owing to the fact that the cleanser is still influential on those residues. It will take the vinegar solution approximately six hours to break down. At that point, it will have removed all of the sediments from the inside of the hot water system. Before turning on the water heater, you should make sure that everyone is aware that it has been out of commission for the past week.

Step 3: Draining of Water.

To clean the water heater, attach the line that comes into the kitchen from the sink. I would appreciate it if you could turn it on and then open the faucet that brings in the cold water. Following that, turn on the hot water tap that is adjacent to the heating element that is responsible for refilling the device.

After that, turn off the drainage system. After detecting that water is pouring out of a valve, you should let the drains and the machine finish washing. Before you plug the drain, check that the water is clean. In addition, there shouldn’t be any bubbles around. To remove the air from a heater, turn on the faucet leading to the heated water. After that, turn the heater back on and drain the water afterward.

Instead of a straight dip pipe, the water heater that has an automatic cleaning system will have a curved one in the tank where the water collects. Here, instead of simply draining water to the foundation, the dip pipe equips with a fitting that sends it whirling around the structure. The sediment keeps moving by agitating the water, which also contributes to reducing the risk of a lime buildup issue.

How Can You Prevent Calcium Buildup?

It is recommended that you empty and clean your water heater once every six to twelve months to remove calcium buildup. If you have hard water, you may need to do it even more frequently to avoid calcium deposits inside the tank from accumulating.

You can take care of this maintenance chore on your own. You can also hire a qualified plumber who can see warning indications of a faulty water heater.

Descaling the tank with vinegar or lime cleaning while also flushing out the tank is an additional option you can do. It can safeguard your water heater against calcium buildup.

You also have the option of having a water softening system installed. It will filter out any minerals that are present in the water before it is heated in the tank for the water heater.


Finally, after reading the article, you came to the ultimate guide on how to remove calcium buildup in a water heater. Calcium buildup can be a great problem for your water heater. It can cause huge damage to your tank and shorten its competency. In summation, you will need to struggle less to remove calcium buildup from water tanks. You can prevent this by implementing a solid maintenance plan. It can happen on your own or by hiring a professional service. This will allow your water heating system to function for a longer period of time.

That is all from us for today.
