When water pipes are placed and replaced, there will be some dust, raw material debris residues and the smell of water pipe materials, so it is unhealthy to use them directly without comprehensive cleaning. Therefore, Shuizi suggested that the new water pipes should be cleaned and disinfected with citric acid before being put into use.
2. Water pipes that have been used for a long time but have not been cleaned
It is recommended to clean the water pipes that have been used for about 2 years. Especially in areas with poor water quality, the inner wall of water pipes may have been soaked and become dirty. The picture shows the cleaning effect of household water pipes after two years of initial cleaning. You can feel it.
Water pipes that have been used for more than 5 years must be cleaned. After a long period of use, tap water contains microorganisms or some "garbage" flowing from other places. If not cleaned, it is easy to produce a large number of bacteria in the water, thus polluting the water quality.
3. I found that the water flow became smaller.
The water flow in the water pipe becomes smaller, and the reason for eliminating water pressure should be caused by impurities such as scale and sediment blocking the water pipe. If the scale is not cleaned in time, it will not only increase the adhesion surface of bacteria and impurities, but also increase the secondary pollution of tap water and the threat of pipe explosion. Of course, the most direct impact of smaller water flow is daily life.
4. The color of the faucet was cloudy when it first came out.
Many families will encounter such a situation: after receiving water in the morning or leaving home for a few days, turn on the tap and find that the water flowing out a few seconds ago is turbid, yellowish brown or black. Why? Because the water pipe is soaked in tap water for a long time, after a long period of precipitation, the substances on the pipe wall dissolve in tap water, which leads to the color change of tap water in the pipe.
5. Replace the filter frequently.
Many people think that after installing the water purifier, there is no need to clean the water pipes. But after a period of time, you will find that the filter element is getting dirtier and dirtier, and the replacement frequency is getting faster and faster. In fact, because the water pipe is dirty, there are more impurities in the tap water, which increases the workload of the filter element of the water purifier.
