When choosing the kitchen faucet, I think more about the question: Can it last long? Will it pollute the water quality? To deal with these problems, we need to understand the structure of the tap first.

The whole structure of the faucet is divided into spool, main body and surface layer. The spool is the part that controls the flow of water in and out, the heart of the faucet, whether it can last or not depends on here; the main body is the primary component of the faucet, that is, the skeleton, most of the water pollution is the poor quality of this part of the material; the coating is the surface material of the faucet, that is, the skin of the faucet, which is the faucet's face value.

1. Can it last long?

The faucet is turned on and off every day. We can't remember how many times it is switched on and off in a day. So the first question we consider when buying is whether it can be used durably. When switching, the active part of the tap is in the spool, so if you want it to last longer, it depends on the quality of the spool.

The quality of the spool can be judged by whether it can withstand durable drip-free inspection, which is aimed at the life test of the spool. It is clearly stipulated in the national water tap test standard that the requirement of no-drip leakage test of switches is not less than 200,000 times. In addition to judging the quality from this test index, it can also be sensory evaluation. Turning the handle up, down, left and right, concise and without obstruction, shows that the quality is excellent.
