SAFETY DEVICE FOR THE PROTECTION OF A DRINKING WATER INSTALLATION RELATIVE TO A WATER ROUTING SYSTEM CONVEYING DRINKING WATER OR NON-DRINKING WATER

摘要

The invention relates to a safety device for securing a drinking water installation (1) with respect to a fluid leading fluid guide system (2), which is connected to the drinking water installation (1), wherein the safety device in the region of the fluid guide system (2) is to be installed to prevent contamination of the in the drinking water installation (1) to prevent led drinking water. To provide reliable protection of the drinking water installation from a fluid delivery system that can carry drinking water or non-drinking water by preventing backflow of Category 5 fluid into the drinking water installation without having to install an expensive, technically complex and maintenance-intensive system with an unrestricted free outlet , the safety device comprises a safety valve (3) preventing the backflow of the fluid from the fluid guide system (2) into the drinking water installation (1) and at least one germ filter (4) designed as an adsorption filter comprising a filter material (5) with an electrokinetic in an aqueous environment , in particular electropositive potential (zeta potential) contains.
