Advice from various international bodies state that when a water softener has been installed then a
separate unsoftened water tap should be provided - mainly for drinking water purposes. This would
normally be at the kitchen sink as this would ordinarily be the main area that people would pour drinking
water from and also used for cooking purposes. Alternative positions for this supply, or more than one
supply can be installed, and is purely down to the individual application. The separate unsoftened
drinking tap should then be connected into the supply pipe prior to the bypass valve and then run directly
to the specied drinking tap. See illustration below.
The Regulations state that “All premises supplied with water for domestic purposes shall have at least
one tap conveniently situated for the drawing of drinking water”. Drinking water must also comply with
the Regulations which stipulate a maximum limit of 200ppm for sodium. The Department of Health
recommends that this sodium level should not be exceeded for baby food preparation and also for
individuals that may be on a low sodium diet.
As the maximum limit is set at 200ppm,it is therefore necessary to check if this would be exceeded in the
area and could be the case where the water is extremely hard. This level of sodium would be exceeded
if the incoming water hardness reaches 425ppm (assuming that the incoming level of sodium is zero
from the mains supply). This can be checked with the Calmag water hardness test kit or alternatively by
asking the local water supplier the level of hardness
and sodium in the area . Once this information is
conrmed then a balanced decision can be made for
the requirements of a water lter or not.
Replacement lters...
Contaminants are trapped within the lter cartridge, therefore you need
to change them on a regular basis to maintain a clean water supply.
The lifespan of a cartridge is dependent on the quality of water passing
through it and we recommend changing lter cartridges every 4-6 months.
