Have you noticed that the tap water at home is getting smaller?

Through the return visit in recent years, I found a thing that is not well known to everyone, and it is also a trouble that we encounter every day. We often encounter such things. When we moved to a new house, the water flow from each faucet was very large and fast. A year later, we found that the water flow slowed down. Occasionally, when the faucet was turned on, it was yellow, like rusty molten iron. Some found that there was an odor just after the faucet was turned on, and we always thought it was. First of all, talk about the water supply pipeline. Since 2000, our domestic water supply (water supply) pipeline is PPR water pipe, and aluminum-plastic pipe is also useful. Individual residential developers use cast iron pipes to enter the house, and the branch pipes are buried in the wall. (Yuhong Garden on Zijingshan Road) Some communities use U-PVC, and some are modified, but many people don't modify it to save money. After the renovation, PPR's water pipes have been in use. The advantages of PPR water pipe are not only smooth inner wall, no scaling, etc. , but also easy to construct. Therefore, if it is a house after 2000, the possibility that the water flow becomes smaller due to the scaling of water pipes can be ruled out. Under normal circumstances, the water pipe of PPR will not scale, and it is not easy to block. Most of them are from faucets. This is because our faucet is blocked. This is because the structure of the faucet is different. Please look at the picture below. This situation is also easy to solve. Unscrew the screw at the water outlet every few months, and wash the impurities inside with water. Especially below the third floor, the pressure of tap water pipeline is also high, and the more impurities there are. If it is not cleaned, it will breed bacteria, bring secondary pollution to water quality and bring unnecessary trouble to people's health. There are ways to eradicate this secondary water pollution, and the next section will talk about water pipe reconstruction and water purification treatment.
