Quick-open Washing Machine Faucet Mdhc8005 with Key

Identify the material and look at the label

High-quality Quick-open Washing Machine Faucet Mdhc8005 with Key mostly use national standard 59 copper or 62 copper (i.e. H59, H62), and the lead content complies with safety standards. You can ask the merchant or refer to the product description/test report.

Pay attention to distinguishing between "brass", "sandblasted copper" and "recycled copper". The former has a uniform color and a clear sound when struck. The latter has uneven color and may have sand holes or pores.

Weigh it and check the inner wall

For faucets of the same size, brass ones are usually more comfortable to hold than stainless steel or zinc alloy ones.

If conditions permit, you can take a look inside. High-quality copper parts have smooth and flat inner walls without obvious burrs or impurities.

Test the feel, heavy valve core

High-quality quick-opening valve cores (especially ceramic cores) have a smooth, neat and elastic switch feel, without any jamming or looseness.

The valve core is the core.

Check the surface and verify the certification

The surface electroplating layer should be as bright as a mirror, uniform and free of flaws. The flatness can be judged by observing whether the reflection of an object is distorted on its surface.

Check whether the product has obtained the national compulsory product certification (CCC certification, if applicable) or other quality certifications.
