How to judge the quality of household tap water?

What is the quality of tap water for household drinking? Should water purifiers be used for terminal treatment? What type of home water purifier should I use? If there is no professional testing and testing means to test these problems, it is more difficult to judge! Here are some simpler methods for your reference.

1. Look: Fill a glass of water with a glass with high transparency, and look at the light to see if there are any fine substances suspended in the water? Let stand for three hours, and then observe if there is any sediment at the bottom of the cup? If there is, it means that the suspended impurities in the water are seriously exceeding the standard; a water purifier must be used for terminal treatment;

2. Smell: Take a glass of water as far as possible from the faucet, and then smell it with your nose. Is there any smell of bleaching powder (chlorine gas)? If you can smell the smell of bleaching powder (chlorine gas), it means that the residual chlorine in the tap water exceeds the standard! Water purifiers must also be used for terminal treatment;

3. Taste: Drink hot boiled water to see if there is any smell of bleaching powder (chlorine gas), if you can smell the smell of bleaching powder (chlorine gas), it means that the residual chlorine in the tap water exceeds the standard! Water purifiers must also be used for terminal treatment;

4. View: Make tea with tap water and observe whether the tea turns black after overnight? If the tea turns black, it means that the iron and manganese in the tap water are seriously exceeding the standard, and a water purifier should be used for terminal treatment!

5. Taste: Taste plain boiled water, is there any astringency in the taste? If so, it means that the hardness of the water is too high, and a water purifier should be used for treatment. The treated water will taste sweeter!

6. Check: Check the water heater and kettle at home, whether there is a layer of yellow scale on the inner wall? If there is, it also means that the hardness of the water is too high (the content of calcium and magnesium salts is too high), and the softening water purifier should be used for softening treatment as soon as possible! Note: water with too high hardness can easily cause scaling of water heater pipes, and pipes will burst due to poor heat exchange; drinking water with too high hardness for a long time can easily lead to various stone diseases.
