How do I remove limescale from an automatic water boiler pipe?

<>There are five or six hundred people in our unit, and we have used two electric water heaters, the first one has been used for a little more than six years, and the current one has been used a year ago.

The advantage of the electric water heater is that it is automatic and convenient, and you can wait to drink hot water when connected to tap water and turned on the electricity. Another point is that in the case of water cut-off, it is very safe for the electric water heater to automatically turn off the power when it is boiled dry.

However, the electric water heater also has a disadvantage, that is, every once in a while, a large amount of scale will accumulate in the heating rod, the wall of the inlet and outlet pipes and the inside of the inner tank. If it is not removed in time, it will not only affect the heating effect and effluent flow of the water heater, but also reduce the life of the water heater.

So, how do you clean limescale inside a water heater? Based on my observations, the following steps are roughly required:

1. Water and electricity cut-off. Instead of simply turning off the power switch and screwing on the faucet, disconnect the water and electricity completely. The purpose of this is, of course, to ensure safety.

2. Drain all the water in the water heater.

3. Remove all the heating rods and inlet and outlet pipes in the water heater, and open the upper cover of the water heater to expose the inner tank.

4. The descaling powder and water are prepared into a solution in a certain proportion, and a part of it is poured into the inner tank of the water heater. Leave a part to soak the heating rod and the inlet and outlet pipes. The soaking time is generally about 30 minutes. If the removal is not complete, it can be repeated. This is the key link.

5. After the scale is removed, rinse the heating rod, inlet and outlet pipes, and inner tank with clean water. It's okay as it is.

6. Connect the water and electricity and carry out test burning. If everything is in order, drain the water used for the test boil. Put in cold water again and you can use it again.

Water heaters generally need to be descaled once a year, but they should not be too frequent, otherwise, the service life will also be affected.

Limescale is because the boiling water we use to boil water will appear for a long time, usually because we use tap water or well water to boil water, if we directly use natural rainwater will not appear scale, mainly because of the cooked, well water contains minerals or impurities, will appear in the boiling water pipe, scale for us is also very harmful, can be we get stone disease, thus causing our body discomfort. Scale should be an alkaline substance, so we often have to clean up the scale in our lives. <>

I will tell you about the method of cleaning scale, we know that because scale is an alkaline substance, so from our chemical point of view, we have to neutralize the scale to remove the scale, so we can generally use vinegar at home to remove scale, because our vinegar at home contains acetic acid, so it is also a better choice for removing scale, because vinegar is cheaper. Another way is to go to our world to buy some Coca-Cola, buy a bottle of more than 500 ml, put a bottle directly in it and use a kettle to boil, so that you can see that the scale in your kettle is gone, because the Coca-Cola in our world also contains carbonated drinks, otherwise how can we call it carbonated drinks. Because after the acid-base neutralization reaction, water and carbon dioxide are produced, so this is not harmful to us.

I've also heard from the adults in the family that there is a way to do it once and for all. It is to use half a pot of water to boil the yams, and it is said that there will be no limescale in the future after cooking, and I have never tried it.

I don't know what you think of these methods.

To clean, simply remove the water heater, pour detergent from the water inlet, and leave it on for a while. Commonly used detergents can be mixed with white vinegar and water 1:, in fact, the dilution of toilet cleaner is also good, and there is a special detergent sold in supermarkets, and 84 disinfectant is placed in a class of goods.

Buy it back and follow the instructions.

If your water heater is a cylindrical water heater heated by electricity, you can use a water pump to inject the descaler solution into the water heater, heat it to a certain temperature, wait for 20 minutes, drain the water in the water heater, and it's OK. You can also separate the shower head from the water pipe, and use a vacuum cleaner to cover the water inlet of the shower head and pump it, and at the same time poke a thin wire into the water hole, which can be cleaned.

The hot water pipe will remain limescale after being used for a period of time, so how to remove the scale of the hot water pipe in the wall?

1. The main component of scale is calcium carbonate.

and magnesium carbonate, if to be removed, with dilute hydrochloric acid.

Soaking is fine, and if you can't find hydrochloric acid, you can soak it in thick white vinegar (or vinegar essence), because scale can be dissolved in acid.

2. Take some vinegar and put it in it quickly to get rid of it by heating it slightly.

3. If it is non-potable water, you can use hydrochloric acid diluent or oxalic acid.

Class high-pressure washing.

4. If it is drinking water, a drinking water anti-scale device can be installed on the pipeline, and the scale in the pipeline will gradually soften and fall off by itself, and at the same time, a protective film will be formed on the inner wall of the pipeline to prevent scale corrosion.

1. Lemon scale: Prepare a lemon, chop it, then put it in the kettle and boil it with water, let it soak in boiling water for a period of time and then pour it all out.

2. White vinegar to scale: this method is the simplest and most practical method, the main component of scale is calcium carbonate and other carbonates, the acetic acid in the vinegar will react with it to produce minerals and carbon dioxide gas dissolved in water, white vinegar can be bought in general supermarkets, put 10% of the white vinegar of the kettle scale, and then fill it with water, boil it for about an hour, and then brush it.

3. Baking soda to remove scale: small judgment such as soda is also to remove the scale of the electric kettle, the general electric kettle heating plate is made of aluminum, when the electric kettle boils water, it is easy to form scale, generally we can put 1 teaspoon of baking soda, boil for a few minutes, and the scale will be removed.

In modern home life, almost every household is equipped with water pipes, which can be used to transport water and play a vital role in our lives. Some friends found that there was scale in the water pipe when using it, but they didn't know how to remove it. 1. How to remove scale in the water pipe 1, we can use baking soda and vinegar to remove the scale in the water pipe, because the composition of the scale contains alkaline substances such as calcium hydroxide, if you want to remove it, you need to use acidic substances to have a chemical reaction with it, baking soda powder and vinegar can effectively dissolve the scale, pour the two into the water pipe, and the scale will dissolve after a period of time.

2. Now there are also dissolving agents on the market that are specially used to remove scale, which are made according to the nature of scale, and the dissolving agent can be poured into the water pipe. Second, how to buy water pipes 1, before buying water pipes to confirm the length of the need to buy and the material of the water pipe, now there are many kinds of water pipe materials on the market, and each has its own advantages and disadvantages, we can buy according to their own needs. 2. We want to buy first-class water pipes, don't be greedy for cheap to buy three no products, so there is no quality assurance, and it is very likely to rupture when used, and it will be more troublesome to deal with.

We should go to reliable merchants to buy water pipes, so that the quality can be guaranteed. 3. What are the matters for using water pipesWhen using water pipes, it is necessary to check whether the water pipes have been ruptured. If it breaks, it will leak and cause water waste.

At this time, the water pipe must be repaired or replaced; If the water pipe is blocked, it is also necessary to take appropriate measures to unclog it in time, and do not leave it there and leave it alone. Summary: The above is the content of how to remove the scale in the water pipe, I hope it can be helpful to you.
