These factors determine the price of the faucet

1. Appearance

The outer surface of the faucet is generally chromed. The plating of the product has the specified process requirements, and after a certain time salt spray test.

No corrosion within the specified time. In the case of sufficient light, the product can be placed in the hands of a direct distance observation. Faucet surface should be bright as a mirror, no oxidation spots, scorch marks. Careful observation, no pores, no blistering, no leakage plating, uniform color. With the hand to touch no burr, no grit feeling. Press with your fingers on the surface of the faucet, fingerprints spread fast, not easy to adhere to the scale.

2、Material

The main parts of the faucet shell are generally made of brass, after sand washing, turning, acid impregnation, pressure testing, polishing, electroplating and other processes. Three bath faucet handle, decorative nut, switch valve basic use brass, zinc alloy, ABS engineering plastics. The wall cover is made of copper, stainless steel and plastic. Connection nuts and eccentric joints, water outlet housing is made of brass. It is recommended to use brass material. The plating quality of products made of brass can be guaranteed and the corrosion resistance time is longer. The higher the purity of the brass, the better the plating quality and the less corrosion-resistant surface coating. Galvanized alloys have poor plating quality and poor corrosion resistance, while ABS process plastics are the cheapest and have poor plating quality. It can be identified by weight estimation, minor surface scratches and surface plating quality. Brass is heavier and harder, zinc is lighter and softer, and plastic is the lightest and softest. However, parts in direct contact with drinking water are not allowed to use zinc alloy materials according to national standards.

3、Function introduction

Faucet styles and functions are various. According to the purpose, it is generally used for wash basin, kitchen sink, bathtub, shower, bidet and so on. According to the function, there are ordinary type, sensor type, thermostatic type and so on.

4、Valve spool

The valve core is the heart of the faucet, ceramic valve core is the best valve core. High-quality products are made of ceramic valve cores, which have strong wear resistance and good sealing performance. Generally can be used more than 300,000 to 500,000 times. Low-grade products are mostly made of copper and rubber seals, which have a short service life. But the price is lower.

5、Surface

The faucet should have a glossy surface, no burrs, no pores, no oxidation spots when touched. The main body of a quality faucet is usually made of copper. After shaping, polishing, the first surface is plated with acid copper, and then plated with nickel, chromium plating (three layers of plating). Ordinary products are generally only nickel and chrome plated (two layers of plating). Ordinary products are coated with specific process requirements, and through the neutral salt spray test, there is no rust in the specified time. Therefore, high-quality faucet products are tightly structured, evenly coated, smooth and delicate in color. After long-term use, they can be kept bright as new.

6、Handle

Turn the handle gently to see if it is light and flexible, there is no blockage. Check the various parts of the faucet, especially the main components are tightly assembled, there should be no loose feeling.
