1. When choosing a faucet, be sure to look at the valve core of the faucet. This is the key to the faucet. Common spools on the market are: copper spool, ceramic spool and stainless steel spool.
2. If you purchase a stainless steel valve core, you must pay attention to whether the stainless steel material passes the customs. Although the stainless steel valve core is a faucet valve core with a higher technology content, if the material is not good enough, it is easier to rust and cause pollution.
3. If you want to buy a copper spool, it also depends on whether the quality of the copper has passed, otherwise scale will easily accumulate, and the price of the copper spool will also be more expensive.
4. Among many faucet valve cores, ceramic valve core is the best, it has good sealing, strong wear resistance, long service life and high temperature resistance. When choosing a faucet spool, it is recommended that the ceramic spool brand is very good and durable.
