Use some tips to determine the quality of drinking water at home:
1. Look: hold a glass of water with high transparency. Look at the light to see if there are any fine substances suspended in the water.
2. Smell: Take a glass of water, try to stay away from the faucet, and then smell it with your nose to see if there is any smell of bleaching powder.
3, taste: drink hot water and taste the taste of bleaching powder.
4. Observation: Make tea with tap water and observe whether the tea leaves turn black overnight. If the tea leaves turn black, it means that the iron and manganese in tap water seriously exceed the standard.
5. Inspection: Check whether there is a layer of yellow scale on the inner wall of the water heater and kettle at home. At the same time, check whether the filter screen of the tap at home will be blocked by some particles. Water with too high hardness is easy to cause scaling of water heater pipes and burst due to poor heat exchange; Drinking water with too high hardness for a long time is easy to cause all kinds of lithiasis.
