When this happens, however, corrosion products in dissolved or solid form are released into the drinking water. If the legal requirements for drinking water quality cannot be met in existing systems due 59030 poor water quality, adverse operating conditions or the selection of unsuitable materials, measures can be taken to correct this by treating the water.

Copper and copper alloys – Plumbing fittings – Part 4: Change in water quality is generally a problem where water stagnates, depending on the materials used in the installation. There are no limitations for the use of unalloyed steel, hot-dip galvanized steel, stainless steel, copper and copper alloys for water heaters, due to the low B values of the heaters, as long as they are operated as intended i.

The effectiveness of any water treatment measures taken is to be determined as specified in DIN and DIN In this case sampling is to be 05930 at intervals of 4 weeks and 12 weeks after commissioning.

These changes are due to microbiotic processes, as well as to the materials with which the water is in contact. Changes to water quality may only be made using the additives listed in the Trinkwasserverordnung, and the limit values listed there are not to be exceeded.

Register online at inter and intra-company training, and certifying diplomas, seminars, distance learning.

Results from a single sample are not sufficient for assessing drinking water in terms of its suitability for human consumption; rather, sampling should be representative of the water consumption, as is specified in DIN Such water is to be compared to the water originally conveyed by the system to see if there is a significant difference in quality, as described in DVGW W Legal notices Photo credits FAQ.
