1. Turn handle: Feel light valve core

Faucet manufacturers design common faucet spool valve core and ceramic spool. Steel Ball Spool has a very good resistance to withstand pressure, but the disadvantage is the sealing effect of rubber ring easy to wear, will soon be aging. Compared with the steel ball spool, ceramic valve core is more heat-resisting wear, and the ceramic valve itself has a good sealing performance, so can achieve very high resistance to opening times, not because of valve core wear caused by dripping water nozzle. Using faucet manufacturers of ceramic spool faucet, feel more comfortable, smooth, and open, close quickly.

2, to test the book: quality is more assured

The main body of the faucet is usually brass. Made of brass products electroplating quality can ensure that the higher the purity of brass plating quality better, the surface of the plating layer is less susceptible to corrosion. Some faucet manufacturers in order to reduce costs, choose zinc alloy instead of brass, although the state allows the use of zinc alloy materials instead of brass, but zinc alloy electroplating quality is poor, corrosion resistance is not strong.

Consumers in the purchase can be used to assess the weight of the method to identify, brass heavier than hard, zinc alloy lighter and softer. But the faucet manufacturers of experts think, should not be a single weight to determine the quality of the faucet, "because some faucet manufacturers by increasing the wall thickness of the faucet or add other metal materials, can also make the faucet heavier." Consumers are best to tap manufacturers to ask the sales staff to test the product report, if the test report identified product eligibility, then "problem is not big."
