After selecting the faucet, improper maintenance will also affect its service life. This is also the most troublesome thing for many people. The frequency of faucet use is quite high. Basically, the faucet is used every day in life. How can the faucet be maintained under such a high frequency of use? 1. When the normal temperature is lower than zero degrees Celsius, if you find that the handle of the faucet handles abnormally, you must use hot water to scald the bathroom products until the hand feels normal, so that the service life of the faucet valve core will not be affected after the operation. 2. The water contains a small amount of carbonic acid, which will easily form scale and corrode its surface after evaporation on the metal surface. This will affect the service life of the faucet. It is necessary to use a soft cotton cloth or sponge to frequently scrub the surface of the faucet. Never use a metal cleaning ball or scouring pad to clean the surface of the faucet. Nor can hard objects hit the surface of the faucet. 3. The dripping phenomenon will appear after the new faucet is closed, which is caused by the remaining water in the inner cavity after the faucet is closed. This is a normal phenomenon. If the water is ticking for a long time, it is a faucet problem. Water leaks, indicating that the product has quality problems. 4. It is not advisable to switch the faucet too hard, just turn it gently. Even the traditional faucet does not require a lot of effort to screw it down, just shut off the water. Also, do not use the handle as an armrest to support or use.
