1, the handle: feel the light spool is a common faucet spool has a steel ball valve core and ceramic valve core. The steel ball valve core has good resistance to pressure, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. Compared with the steel ball valve core, the ceramic valve core is more resistant to heat and wear, and the ceramic valve core itself has a good sealing performance, so that a high degree of opening resistance can be achieved, and the nozzle is not dripped due to the wear of the valve core. The faucet with ceramic valve core is more comfortable and smooth in hand, and it is quick to open and close. Since the spool is inside the faucet, the consumer can't see the spool when purchasing, but the consumer can simply judge whether the spool is good or bad according to the feel when turning the handle. Generally speaking, turning the handle up, down, left, and right, if it feels light and has no blockage, it means the spool is better.
