Double Handles Bathroom Faucet

1. Copper body: As far as the faucet is concerned, copper has long become the preferred material, mainly because the antibacterial effect of copper media has long been recognized by authoritative laboratories. Most high-end bathroom brands use copper as the body of the faucet, and the elimination of other materials has become an inevitable trend.
2. Electroplating: The quality of the electroplating surface is the most intuitive expression of the quality of the faucet. The surface plating is mainly nickel and chromium, so that it achieves a smooth and bright effect. Good quality faucets will undergo many tests, such as salt spray test, water test test, gas test test, etc., to ensure the durability of the faucet. After high-precision plating faucet, durability is basic, and more importantly, its surface gloss is good and comfortable to handle. Some high-grade faucets have other different treatment techniques, such as stainless steel and satin.
3. Filter screen: In areas where the water quality is not superior, the installation of the filter screen can reduce and filter impurities, and at the same time prevent the possible damage caused by impurities to the ceramic valve core. There are two installation locations for the filter: the water inlet and the spout.
4. Rotation angle: can rotate 180 degrees to make the work convenient, and can rotate 360 degrees is only meaningful for a sink placed in the center of the house.
5. Can lengthen the shower head: increase the effective radius, increase more functional possibilities, and the sink and container can be filled faster. In order not to make unpleasant noises, metal pipes should be avoided as much as possible.
6. Water pipe length: Experience shows that 50 cm long pipes are enough, and pipes of 70 cm or more can also be bought on the market.
7. Anti-calcification system: calcium will be deposited in both the shower head and the automatic cleaning system, and the same situation will occur on the faucet, where silicon will accumulate. The integrated air cleaner has an anti-calcification system that prevents calcification of the device internally.
8. Anti-backflow system: This system prevents dirty water from being sucked into the clean water pipe, which is composed of layers of materials. Devices equipped with an anti-backflow system will display the DVGM pass mark on the surface of the package.
9. Material: Stainless steel is hygienic and environmentally friendly. Chromium devices are easy to care for and harmless to people, but other elements need to be added to the manufacturing process. Therefore, it must be paid attention to what materials the equipment is made of, and not all countries have such high standards as Germany.
10. Durability: The anti-calcification system can protect the equipment from the danger of water leakage and handle damage.
