Microbiological and sensory quality of the (partially) softened water
The quality of the treated water depends greatly on the conditions under which the unit is installed an operated. The most important factors are
listed in the following table.
Inflow water quality
Operating conditions
Salt quality
Installation situation and
conditions
When determining whether there is a problem with the sensory or microbiological quality of the treated water, it is important where in the system the
quality is measured. For example, if the quality is measured at the tap, the water quality may be affected by the pipe material or by the presence
of a water heater or hot water storage tank.
Unfavourable conditions
Borderline inflow water quality, which can become
even worse within the unit
Long stagnation times and
infrequent regeneration
Cheap regenerative salts with high proportions
of insoluble components
High ambient temperatures, e.g. near a heating
unit
Drainage system for regeneration water incor-
rectly designed

Important notes

NOTE
The unit must be installed as described in the installa-
tion guide in compliance with the general requirements
for the supply of water in Germany ["AVB Wasser"] V,
section 12.2 by a water supply company or by a party
registered in the water supply company's index of fitters.
In keeping with TrinkwV § 16 and § 21 (German
drinking water ordinance), notify residents of the
installation of the water softener, explain how it
works and which regenerative is used.
Using treated drinking water with plants and aquatic animals
Each species of plant and aquatic animal requires water that contains
a special combination of substances. Users of the unit should therefore
consult the standard literature and check that they can use retreated
drinking water for watering plants or for filling ornamental lakes, aqua-
riums or fish ponds.
