Welcome!
The anti backflow system prevents dirty water from being pumped into the clean water pipe, which is composed of layers of materials. Equipment with anti backflow system will be marked with DVGM passing mark on the package surface. Experience shows that 50 cm long pipes are enough, and 70 cm or more pipes can also be bought on the market.
The quality of the electroplating surface is the most intuitive expression of the quality of the tap. The surface is mainly plated with nickel and chromium to achieve a smooth and bright effect. The faucets with good quality will go through many tests, such as salt spray test, water test, gas test, etc., to ensure their durability. The faucet with high precision electroplating is basically durable. More importantly, its surface gloss is good and it feels comfortable. Some high-end faucets have other different treatment technologies, such as stainless steel surface and satin.
