Για πόσιμο νερό δεν χρησιμοποιούνε χαλκοσωλήνες.
Απαγορεύεται δια ροπάλου.

Σε ολο τον κοσμο χρησιμοποιουνται εδω και δεκαετιες χαλκοσωληνες για υδρευση και ποσιμο νερο.
Μαλιστα θεωρουνται ασφαλεστεροι απο τους χαλυβδοσωληνες

In addition, copper gives excellent protection against contaminants to the domestic water supply. Nothing can get through: no fluids, no germs, no oxygen, no ultra-violet rays - nothing. Copper doesn't absorb organic substances, and cannot be softened by them in service.

Copper is a natural, environmentally friendly-element that has been used to deliver drinking water since the time of the pharaohs. However, only recently have scientists discovered the public health benefits of copper plumbing tube.
The antimicrobial effects of copper helps copper plumbing tube to preserve the purity of drinking water. Copper plumbing tube has been found to inhibit water-borne microorganisms, such as bacteria, viruses, algae, and infectious parasites, in the drinking water supply that resides in the plumbing tube. These microorganisms can pose a variety of health risks to humans, including Legionnaire's Disease, deadly E. coli infections, and polio.
Although potable water is generally free of pathogenic organisms, it is possible for viruses, bacteria, fungi, and parasites to thrive in public drinking water systems. Copper plumbing tube is an effective way to help protect against the presence of these organisms and the possibility of disease. The positive effects of copper plumbing tube on destroying pathogens have been documented even when the copper levels in the water are below guidelines for potable water.
Since copper plumbing tube is non-porous, it can prevent petrochemicals, insecticides, and organic contaminants from absorbing into the tube and polluting the water supply.

Copper plumbing tube has a unique ability to reduce the threat of disease from opportunistic waterborne pathogens. Controlled laboratory tests demonstrate that certain viruses and bacteria, such as the Polio virus, E-coli O157, and Legionella pneumophilia, which causes Legionnaire's Disease, are inhibited by copper plumbing tube.
In test samples, 97% of Polio virus type 1 and 96% of Polio virus type 2 were reduced by passage through "aged" copper plumbing tube. In new copper plumbing tube, 80% of Polio virus type 2 was removed within 3 hours. The virus was completely eliminated within 24 hours.
The same experiments also demonstrate that it does not take high concentrations of copper in water to reduce the viruses. In circumstances simulating overnight stagnation in copper pipes, only 0.6 mg of copper per liter was leached to the water, a level significantly below WHO guidelines. This suggests a significant public health benefit from the use of copper plumbing tube, as well as an added benefit from the overnight retention of drinking water in copper plumbing - without the risk of ingesting excess copper.

Prior studies have demonstrated this antimicrobial behavior of copper and the inhibitory effect of copper plumbing tube on bacteria and viruses. It has been demonstrated that copper plumbing tube inhibits the growth of Pseudomonas fluorescens, Bacillus subtilis, and Bacteriophage MS2, which can cause gastrointestinal disturbance. In all cases, these beneficial effects were registered in tap water containing copper concentrations that were well below drinking water guidelines.

Ριξτε και μια ματια στο site της ΧΑΛΚΟΡ ( www.halcor.gr) οτι οι χαλκοσωληνες που παραγει στην Ελλαδα ειναι πιστοποιημενοι για ποσιμο νερο απο τους οργανισμους :
DVGW - RAL - NSF - bsi


Αλλα μας πειραζουν οι χαλκοσωληνες οταν το κεντρικο δικτυο διανομης νερου εχει τα χαλια του
