1. Unplug the power plug, wrap the plug with leakage protection and place it on the water heater body. Seal the socket. To prevent water from entering.
2. Close the water inlet tap and remove the mixing tap.
3. First place a large bucket under the sewage outlet, remove the red plastic cover outside the sewage outlet next to the water outlet pipe, and use a wrench to remove the outlet nut Wastewater. At this time, all the water from the water heater flows into the bucket.
4. When I saw that the running water no longer had pressure and the water was starting to change color, I changed the connection on the bucket. It didn't take long for the sewage to flow out and the water in the electric water heater to drain.
5. Pour the cleaning solution directly from the waste water outlet with a syringe or similar, block the waste water outlet agains, block the water outlet, connect the water inlet pipe and add about two-thirds of a bucket of water. And the process of adding water is sometimes full of water and sometimes little water.
6. After about 30 minutes, open the drain outlet to drain the water and add water several times to flush the water heater three times.
7. Reinstall the water heater and replace the cap. This concludes the wastewater cleaning work.
How to clean the pipes of a solar water heater
Start with the scale If you haven't washed it in five years, it must be there have a thick layer of tartar. . When cleaning, clean water is used. If you can't wash it, you need to use detergent. In general, solar water heaters should be cleaned 2 to 3 times a year. It is not only clean and hygienic, but also poses no cleaning problems. Although solar wateris not intended for consumption, it will also cause us skin problems. .
The thermal conductivity of scale is very low, hundreds of times lower than that of metal, so scale should not be too thick, if it is too thick it will act as a thermal resistance. which will lead to an improvement in the thermal conductivity of the water heater. In addition, scale will cause local overheating of the wall of the metal pipe. When the wall temperature exceeds the limit, it will cause local deformation, bulging or even rupture. Once the vacuum tube of the solar water heater is scaled, it directly blocks the circulation of water inside the water heater, causing heat to transfer from the vacuum tube to the water tank, resulting in a slow increase in temperature.
First of all, the water in the solar energy must be drained, then put on gloves anti-collision to remove the vacuum tube. After removing it, pour in an appropriate amount of white vinegar and let it soak for a while. Then brush it several times with a fine brush and rinse it with clean water. What happens if it is inconvenient to remove the vacuum tube? We can pour white vinegar into the incoming water, let it circulate for about 30 minutes, then release the water from solar energy.
Vacuum tubes that have been cleaned with white vinegar or circulation methods will have an unpleasant odor due to chemical reactions. After washing, scrub with lemon juice or add a little lemon juice to the cycle to eliminate odors. But if the time is too long, this method may not be able to be washed. You can ask professionals to help you wash. If you don't want to find professionals and don't want to clean, you can useanother practical method. can alleviate the problem. Install a filter in front of the solar solenoid valve.
The solar water heater is an environmentally friendly and energy-saving device, but used long term. , the pipes will also be blocked. If it is not cleaned in time, it will affect the normal use of the solar water heater. Here are some methods to unclog solar water heater pipes, which can help you solve this problem.
1. Free dredging method
Free dredging method refers to the use of special hooks or thin curved rattan sticks, bamboo sticks and other materials to be inserted from the pipe mouth inward, and then push it by hand, when you encounter an obstacle, gently shake it and move it back and forth to loosen it, then take it out. This method is relatively simple and pratic, but if the blocked material is relatively hard, the unblocking effect may not be very good.
2. Hydraulic unblocking method
The hydraulic unblocking method involves injecting clean water into the pipeline and using pressure to force the pipeline blockage. Construction can be accomplished with sprinklers or other high flow water sources. Normally, you can use a screwdriver to unscrew the drain outlet or ordinary motor outlet, and then pour or spray water into the drain pipe to clear the blockage. This method requires relatively high water pressure and is more suitable for situations where a lot of scum and dirt are attached to the pipe after long-term use.
3. Acid and alkali dredging method
Acid and alkali dredging method refers to the use of acid and alkali for cleaning, which has a certain effect. SomeAcidic substances such as acetic acid and fruit acid can be used to remove rust and grease from pipes. You can also use alkaline substances such as laundry detergent, etc., and put them down the drain to clean them. However, this method requires careful attention to the selection of materials and the correctness of the cleaning method, otherwise it will affect the service life and health of the pipeline.
4. Vibration dredging method
The vibration dredging method involves first fixing the pipe, then using a hammer or other tools to gently tap the pipe and vibrate it to remove the des solids in the pipe are loose. This method is more suitable for the case where the material in the pipeline is relatively light, but the effect is not very good for relatively hard materials.
In short, there are many methods to unclog canalsinstallation of solar water heaters. It is better to choose the corresponding method according to the cause and situation of the blockage to avoid secondary damage to the pipes. At the same time, you should also pay attention to the use and maintenance of the pipelines, clean them in time, and inspect them regularly to keep the pipelines clear to prolong the life of the solar water heater.
