Nickel or chromium has the function of resisting neutral hydrochloric acid, protecting the faucet from corrosion for a long time. When purchasing, look in a well-lit place. The surface of the faucet is free of oxidized spots, no air holes, no missing plating and blisters, and scorch marks. The uniform color without burrs and sand grains is a good product.
3, pay attention to the internal structure and material
When purchasing, please read the instructions to understand the internal structure of the faucet. Ceramic faucet faucets are recommended. They are made of high-durability ceramics. Even 60 pounds of water pressure can be switched freely without leakage. For washers, the recommended washers can withstand hot and cold water pressure without leakage.
4, inspection faucet switch structure
Finally, check the design rationality of the product. First move the switch a few times to see if the parts fit tightly and tightly. When turning the switch, feel soft. If the hand feels astringent or frivolous, it indicates that the assembly structure is unreasonable.

At the same time, when using or not using, pay attention to the joint between the hose and the valve body not to form a dead angle, so as not to break or damage the hose.
3, in the case of water pressure not lower than 0.02mpaz, after using for a period of time, if you find that the amount of water is reduced, or even the phenomenon of water heater turn off, you can gently unscrew the screen cover at the faucet outlet, Remove impurities, generally can recover freely.
4, when the temperature is lower than zero, if you find the handle feel abnormal, you must use hot water shower hot bathroom products to feel normal, in order to continue to use. On the contrary, it will affect the service life of the valve core.
5, because the water contains trace amounts of carbonic acid, and easy to form scale after evaporation on the metal surface will have a corrosive effect on the faucet surface, thus affecting the cleaning and service life of the faucet. Therefore, often use a soft cotton cloth or sponge with neutral soap water to wipe the surface of the faucet (Caution: It must not be wiped with corrosive or acidic substances), and then wipe the surface with a soft cloth.

Faucet faucet lead exceeded
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
