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 it stand for three hours, and then observe whether there is sediment at the bottom of the cup? If there is, it means that the suspended impurities in the water have seriously exceeded the standard.

2. Smell: Take a glass of water as far away as possible from the faucet, and then smell it with your nose. Is there a smell of bleach (chlorine gas)? If you can smell bleach (chlorine gas), it means that the organic matter in the tap water exceeds the standard or the residual chlorine content is high.

3. Observation: 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 exceeded, and a pure water machine should be used for terminal treatment.

4. Taste: Taste the boiled water, does the taste feel astringent? If there is, it means that the hardness of the tap water is too high.

5. Check: Check whether there is a layer of yellow scale on the inner wall of the water heater and kettle at home? If there is, it also means that the hardness of the water is too high, and softening treatment should be used as soon as possible! Note: Water with too high hardness can easily cause fouling of water heater pipes, waste energy due to poor heat exchange, and even burst pipes. Drinking water with too high hardness for a long time can easily cause various stones.
