If the faucet at home is not tightly turned off, frequently drips water, and the water comes out hot and cold, many people will directly replace the entire faucet. In fact, most of the faults lie in the valve core. The maintenance industry reminds us to learn how to distinguish between good and bad valve cores, avoid traps when choosing, and prevent water leakage risks in advance.

At present, the mainstream of household faucets is ceramic valve cores, and the national standard requires qualified products to withstand 50000 cycles of opening and closing without leakage. Poor quality ceramic valve cores have low purity and rough polishing, and are prone to sealing failure after 1-2 years of use. In severe cases, the valve core may crack and leak water, causing property damage.

Industry shares three simple identification methods:
One is the tactile test. High quality valve core rotates smoothly, with even damping, no jamming or rustling noise, and can be lightly twisted to stop water; The poor quality valve core rotates awkwardly and needs to be tightened tightly to turn off the water.
The second is home self-examination. Continuous dripping of water after the faucet is turned off, water seepage at the root of the handle, and fluctuating water temperature indicate that the valve core has been worn. Scale and sediment in hard water areas can easily scratch ceramic tiles and accelerate damage to valve cores.
The third is to view product information. Legitimate products will label the valve core brand and parameters, and choose brands with good reputation for valve cores; Low price three no products often come with inferior valve cores, which poses greater risks.
 

The repairman suggests not to forcefully twist the switch faucet to reduce valve core wear. If there is a valve core failure, there is no need to replace the entire faucet. Simply replacing the valve core can be repaired at low cost. When choosing a faucet, don't just look at its appearance, the quality of the valve core is the key.
