When choosing a faucet, it's important to understand the different materials available. Most faucets are made from stainless steel, zinc alloy, or copper. Among these, red copper is considered the highest quality due to its durability and corrosion resistance. If you're selecting a faucet, check the surface for smoothness and ensure there are no sharp edges or burrs. The outer coating may be galvanized, titanium-coated, or painted. A high-quality finish should be even, bright, and thick, as this helps prevent oxidation and rust over time.
To test the functionality of the faucet, gently turn the handle. It should move smoothly without any stiffness or resistance. Check the switch mechanism for tightness and ensure there are no visible gaps. A well-made faucet will feel solid and not slippery. On the other hand, lower-quality models may have larger gaps and feel rough or unresponsive.
If you tap the body of the faucet, a good one should produce a clear, ringing sound. A dull sound may indicate it's not made of copper or stainless steel, which could mean lower quality. Inspect the connections carefully—good faucets usually have precise assembly. High-quality models often use brass for the valve body and handle, which makes them heavier and more durable.
Check all parts of the faucet for proper assembly and tightness. Most single-handle faucets come with an installation diagram and user manual. Before using the product, always open the packaging and verify that it has a valid inspection certificate to avoid purchasing "three-no" products (no manufacturer, no quality, no warranty). This is especially important when buying imported items.
Additionally, make sure all accessories are included and in good condition. A complete set typically includes: (1) solid bolts, copper washers, and gaskets; (2) a full set of water lifters; (3) two inlet pipes; and (4) two angle valves. When selecting hoses and angle valves, choose reliable brands. These small components can significantly affect the overall lifespan of your faucet. One recommended brand is Fujian Jianglong Plumbing Co., Ltd., known for producing high-quality fittings.
