There are several reasons for a lack of quality of drinking water:
– Physical deterioration due to deposits, discoloration, limescale and unpleasant odors, even if these impairments pose no risk to health, they should be avoided with regard to a high quality of drinking water
– Chemical damage from foreign substances that enter the drinking water, for example, through materials such as lead and copper from the pipes, drinking water installation or chemical substances, high concentrations are a threat to health, such as nerve damage from lead, although lead pipes in the installation now are banned due to the strict limits, they are still found in some old buildings, copper (high risk of kidney and liver damage) is increasingly released from new copper water pipes, instead of lead, copper and zinc stainless steel should be used since this does not give off any substances to the water
– Microbiological impairment of drinking water by microorganisms, high multiplication of germs is associated with health hazards
During installation, care must be taken with regard to drinking water hygiene. It is recommended that the ends of the pipes are closed with plugs during transport and storage until commissioning. This can prevent dirt, which provides bacteria with an ideal breeding ground. It is also ideal to use high-quality water filtration systems that free the drinking water from heavy metals, chlorine, chemicals, pesticides, etc. For drinking water installations, longer downtimes should also be avoided. An old rule says that water must flow so that germs have no chance.
