What color color does the water come out of the water heater after descaling?

Most users may not be familiar with the cleaning of water heaters, even if they have never noticed and do not understand the importance of cleaning water heaters. Sometimes, after the water heater is cleaned, the water turns yellow, but the reason is completely unknown. Such questions are relatively simple and everyone should pay attention to them because they are relatively simple, but they have a great impact on life.

What is the reason why the water heater is always clean and yellow? Let's take a look at the reasons and solutions.

Why is the water yellow after cleaning a water heater? After the water heater is cleaned, the water has turned yellow, which may be a problem with the water tank, so it should be cleaned in time and check whether the water heater is working properly every year. The electric water heater tank needs to be cleaned regularly.

The general cleaning method is relatively simple. First cut off the power supply, close the water inlet valve, then open the outlet valve, turn the drain switch on the bleed valve counterclockwise, discharge the water and dirt in the water heater naturally, and then clean it with tap water. After cleaning, reset the drain switch, and pay attention to putting in an appropriate amount of water before powering on.

We can also unscrew the trap nut and connect the metal hose of the cold water pipe to the hot water outlet of the water heater (red button in the middle). Then open the cold water valve so that the cold water can rush from the hot water pipe to the liner. In this way, the sewage inside the inner container can be quickly discharged and washed several times until the water inside the inner container becomes clean.

There is also a relatively easy way to solve this problem. Just unplug the hot water pipe and you'll see the water coming out of the pressure reducing valve, and you'll be letting the water out of the tank. When no water is flowing out of the pressure reducing valve, the water in the tank will essentially be released.

At this point, most of the flocculent in the inner tank will also be released.

For friends who want to use the water heater all the time, the most important thing is to check whether the water heater is running properly, and when there is a big problem, send it to the maintenance point for repair in time. When the water heater is in normal use, it is recommended to replace the thermostat and heater every 3 years.

The water that comes out of the water heater is basically yellow, just like the yellow mud soup we usually say. Because of the long time, the water in the water heater will not form rust.

After the water heater removes the scale, the color of the water will not change, and it will still be the same color of the water. When limescale is removed, it will be cleaner and the color of the water will not change.

What color color water comes out of the water heater descaling? Normally, the water we come out of is muddy. It's very dirty to look at. It can only be used after it has been cleaned up.

The water that comes out after the water heater is descaled is about the same color as the soil, gray-brown, and it can only be used when the water comes out.

The color of the water coming out of the water heater is slightly yellowish milky white after descaling, which is relatively turbid.

After descaling, it is recommended to disconnect the outlet of the water heater from the hot water pipe, turn on the cold water switch, fill the water heater with water, and rinse it twice. This allows the scale to be flushed out from the inside of the water heater.

The water that comes out of the water heater is generally white sewage, and if it has not been cleaned for a long time, the cleaned water is black. There are a lot of microorganisms and impurities in tap water, which will accumulate there over a long period of time and need to be cleaned regularly.

If the water in your area is hard and your water heater has been in use for a long time, there will definitely be limescale in it.

It is usually waterproof to clean up limescale stains.

The specific cleanup method is as follows:

If there is a drain nut on the far left under the water heater tank, cleaning is very simple, unscrew the nut, and at the same time pump out the magnesium rod inside to drain the water in the tank. When the water is almost empty, the limescale stains deposited at the bottom of the tank will be brought out. After draining the water, temporarily screw the drain nut on, then add a little water to the tank before discharging it.

Repeat this several times, and wait for the water to be thoroughly cleaned, it means that the scale is cleaned up, insert the magnesium rod and then tighten the sewage nut to add water to the water tank, and then turn on the electricity to heat it after the water is full.

Some water heaters have a plastic base underneath the tank, and the base needs to be removed to see the drain nut on the left side.

If the water heater does not have a special sewage nut, it is necessary to remove the water pipe on the right side, and then remove the safety valve, so that the water can be discharged, and after the water is finished, temporarily connect the water pipe to add some water to the water tank, and then release it, so that the scale in the water tank can be removed several times, and finally the safety valve and water pipe can be reinstalled and reset to add water to the water tank, and the water can be used when the water is full.

Whether to replace the magnesium rod depends on the degree of corrosion and dissolution of the magnesium rod, and most of the magnesium rods used by manufacturers are long-term magnesium rods, which are very durable and basically synchronized with the service life of the water heater, so there is no need to better magnesium rods. In addition, it should also be noted that it is best to adjust the water temperature reasonably according to the ambient temperature of the season, the higher the water temperature, the easier it is to produce scale, so try to lower the water temperature of the water tank, especially in summer, usually adjust the water temperature setting at about 40 degrees. In many areas along the southern coast, there is no need to replace the magnesium rod because the tap water quality is softer and will not produce scale, but the dirt in the water tank should also be cleaned regularly.

Storage electric water heater, usually the power is about 1500-2500W, it is best to replace the power socket of the water heater with a 16A switch, and control the opening and closing of the water heater power supply through the switch, so as to avoid frequent plugging and unplugging of the power plug is prone to poor plug and socket contact and resulting in the fault of heating and ablation.

How to save electricity in a storage electric water heater depends on the frequency of use. If the frequency of use is high and hot water is often needed, it should always be kept on the state, which is both convenient and relatively energy-saving; However, if the frequency of use is low, and you only occasionally use hot water for bathing, you should use electricity to heat it before use, which is also more energy-saving. Especially in summer, it is generally heated for about 15 minutes to meet the temperature requirements of the bath, so the operation is very energy-saving.

With the function of temperature regulation, the water temperature should also be reasonably set according to the seasonal ambient temperature and the amount of water used, and the water temperature can be adjusted at about 40 degrees in summer, so that it is more energy-saving. But in winter, if you are in the north, because the ambient temperature is low, you must heat the water to the highest temperature, otherwise the hot water will not be enough.

How to Prevent Water Heater Limescale?

1. Unplug the power socket of the hot water, cut off any form of heating of the water heater, and close the angle valve of the water heater.

2. Open the seal of the water heater and replace the magnesium rod in the electric water heater.

3. Remove the limiting device of the wrench of the pressure relief valve, and connect the small pipe of the pressure relief valve to the small pipe of the pressure relief valve with a plastic pipe to draw out the water in the inner tank.

4. Disassemble the metal hose joint at the hot water pipe, at this time there will be water flowing out of the pressure relief valve, and when there is no more water flowing out of the pressure relief port, the water in the inner tank will basically flow out.

5. Next, connect the metal hose of the cold water pipeline to the hot water outlet of the water heater, open the cold water angle valve, and let the cold water rush into the inner tank of the water heater from the pipeline.

Before cleaning the electric water heater, you need to unplug the power supply, cut off any form of heating of the electric water heater, and turn off the cold water and hot water angle valves under the electric water heater.

Open the seal of the water heater and replace the magnesium rod inside the electric water heater. The function of the magnesium rod is to reduce the corrosion of the heating pipe, so that the scale has a chemical reaction, and the long-term use of the magnesium rod will produce flocculent or hard lumps to wrap the rod surface until the magnesium rod is completely consumed. Therefore, it is best to replace the electric water heater with a new magnesium rod in time for long-term use, otherwise it is easy to leak water and electricity.

Remove the restraint device of the pressure relief valve wrench (usually a plastic square hole part, used to prevent the pressure relief valve from being accidentally opened), and connect the small pipe of the pressure relief port of the pressure relief valve with a plastic pipe to draw out the water in the inner tank; Turn the wrench of the pressure relief valve from the vertical position to 90 degrees, and the pressure relief valve has been opened.

Disassemble the joint of the metal hose at the hot water pipe, then you should see that there is water flowing out from the pressure relief valve, release the water in the inner tank, and wait until the nozzle of the pressure relief valve basically no longer has water flowing out, the water in the inner tank has basically been released, and then most of the scale (flocculent) in the inner tank will also be discharged.

Next, connect the metal hose of the cold water pipe to the hot water outlet of the water heater, open the cold water angle valve, and let the cold water rush from the hot water pipe to the inner tank, and then you can see that the water mixed with scale continues to flow out of the outlet of the pressure relief valve. After repeated repeated steps, after many rinsings, the water flowing out of the outlet of the pressure relief valve is already very clean, indicating that the inner tank is basically clean.

Restore the pressure relief valve to its original appearance, put the lever down again, reconnect the hot water pipe with the hot water angle valve, and reconnect the cold water pipe with the cold water angle valve; Open the hot water angle valve and the cold water angle valve respectively, open the hot water faucet at the hot water pipe faucet connected to the hot water angle valve (such as the hot water faucet in the bathroom, or the hot water faucet in the washbasin), and then turn off the hot water faucet after the water comes out of the hot water faucet, so as to ensure that the inner tank has been emptied of air and filled with water.

Check whether there is leakage at each joint, and reconnect if there is leakage to ensure that there is no leakage at each connection. Plug in the electric water heater, turn on the power, check the heating situation, everything is normal, and the cleaning work is completed.

If there are many of them, it is better to sell special descaling powder, which will be better. This kind of descaling powder is generally sold in the sales of household appliances. Of course, it is more appropriate to wipe it off with a cleaning ball in time when there is less limescale.

There is limescale cleaner sold in the store. You can get a pack for a few bucks.

There are generally three ways to clean up the scale in the storage electric water heater tank:

1. Some water heaters have special sewage nuts under the water tank, and this kind of water heater can discharge water and sewage by directly unscrewing the sewage nuts. When the water in the tank is almost empty, the scale inside the tank will be carried out. After draining the water, screw the nut on, add some tap water to the water tank, and then unscrew the drain nut to drain the water, so that the scale in the water tank can be cleaned up several times.

2. Some water heaters can discharge water and sewage by adjusting the angle of the safety valve, but the water discharge is too slow and the effect is not good;

3. For water heaters without special sewage nuts, it is best to remove the water pipe and safety valve with a safety valve on the right side and discharge the water discharge.

Before cleaning the scale, the user had better read the manual of the water heater in detail, and it is advisable to clean the scale according to the operating requirements of the manual.

Go clubbing with vinegar! It's slower.

White vinegar to go down,. After a few hours.

Install a scale preventer directly on the inlet pipe of the water heater to remove scale, not only will no new scale be generated, but the old scale will also fall off.

How to Prevent Water Heater Limescale?

Limescale can be roughly divided into two types: hard scale and soft scale according to the reason for its formation and forming state. When the water contains impurities such as carbonate colloids, bacteria and organic matter, the carbonate is similar to the sand and gravel in the cement mortar, and the colloids, bacteria and organic matter are equivalent to the cement in the cement mortar. Once viscous substances such as colloids, bacteria and organics have been removed (e.g. by ultrafiltration), even if the concentration of calcium, magnesium and carbonate ions in the water is high, it is carried out into a white and loose carbonate soft scale that can be easily removed, without the formation of hard scale.

Composition: The composition of scale is generally complex and is made up of many compounds. The chemical composition of limescale is generally expressed in terms of mass fraction.

Classification: Scale is divided into calcium and magnesium scale, silica scale, phosphate scale, iron scale and copper scale according to its main chemical components.

When the scale thickens to a certain extent, it will not only prolong the heating time, but also crack, which will damage the inner tank, so that the heating time will be extended and the amount of hot water output will be reduced. Electric water heaters do not have a blowdown valve and need to be cleaned by professionals.

Household electric water heaters are prone to limescale.

Professional maintenance personnel said that the reason why there is such a problem in the electric water heater is that the inner tank is scaled. According to reports, the heat exchanger of the vast majority of electric water heaters is made of copper, but the thermal conductivity of copper is much higher than that of carbonate scale, so when the scale deposit is covered on the heat exchange surface of the heat exchanger, the heat exchange efficiency will be greatly reduced. Moreover, after the scale is covered on the surface of the heat exchanger, it will produce corrosion under the scale, preventing the effective heat exchange of the electric water heater, so that the heat exchange surface will be in a state of high temperature heat load for a long time, resulting in metal fatigue, and when the scale is serious, it will also cause pipe bursting.

Because of these circumstances, electric water heaters that have been used for about a year or two will always have the problem of slow heating.

It is best to clean the household electric water heater once every six months.

Limescale in household electric water heaters will not only cause an increase in electricity consumption, but also easily cause safety accidents. Especially in some areas with poor tap water quality, such as yellow muddy water often occurs in some areas, it is more likely to form scale. The best way to remove limescale is to clean it regularly, and maintenance personnel recommend that it should be cleaned once every six months.

Although some families often clean their electric water heaters, most of the scrubbing is on the outside, and there are very few families that really clean the inner tank thoroughly. Maintenance personnel recommend that the electric water heater be bathed regularly; It can not only prolong the service life of the electric water heater, improve the use efficiency, but also ensure the safety of use more effectively.

There is a recipe for cleaning household electric water heaters.

At the same time, the maintenance staff reminded consumers that bathing an electric water heater requires special skills and can only be operated by professionals. The maintenance staff gave consumers a simple way to clean the water heater on a daily basis.

Clean the inner tank every six months, first cut off the power supply, close the water inlet valve, then open the water outlet valve, and rotate the drain switch on the safety valve 90 degrees counterclockwise to naturally drain the water and sediment in the household electric water heater. Then wash it with tap water. After cleaning, return the drain switch to its original position, and pay attention to the power on only after it is full of water.

Precautions. Users who do not turn off the power supply of household electric water heaters all year round should often check whether the electric water heater is normal, and send it to the maintenance point for maintenance in time if there is any abnormal situation. When the water heater is in normal use, replace the thermostat and heater at the designated maintenance point every three years. If the water output of the shower is reduced, it is necessary to clean up the blocked debris in time to ensure that the outlet is unobstructed, which is helpful to prolong the service life of the water heater.

In addition, members of the public should not replace the parts on the electric water heater at home to prevent unnecessary trouble.
