Stainless steel is sanitary and environmentally friendly. The equipment for chrome soldering is easy to care for and harmless to people, but other elements need to be added in the manufacturing process. Therefore, we must pay attention to what materials the equipment is made of. Not all countries have such high standards as Germany. The anti calcification system can protect the equipment from water leakage and handle damage.

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.
