Faucet self-test method:
1. Add soapy water, the hard water is hard water (the content of calcium and magnesium is too high), and the other is soft water.
2. Check the water heater in the house and the inner wall of the kettle for a layer of yellow scale. If it is, it also indicates that the hardness of the water is too high, and it should be softened as soon as possible using a softened water purifier.
3. Using the acid-base indicator, it is simple and convenient.
4. Use tap water to make tea. After the night, observe whether the tea is black. If the tea turns black, it means that the iron and manganese in the tap water are seriously exceeded.
Using the above methods, you can easily and conveniently measure the safety of your home water without leaving your home!

Heavy metal precipitation:
When buying faucets, attention should be paid to the content of heavy metals.

Among them, the lead precipitation statistics can not be greater than 5μg / L.
In the latest national standards, the safety of the handle is also required. In the purchase process, we should pay attention to whether the handle of the faucet is light, stable and free of jamming.
The fit between the handle and the spool during use is firm and there is no sign of looseness.
