Descalers don’t remove lime from the water, but it changes the composition of it to prevent further build up after descaling took place.
The real risk lies in that it can start building up again, which is the reason your geyser and other electrical accessories will continue to break.
If “descaled” water lies still for too long or it gets above a certain degree of heat (as in a geyser), the lime may start building up again. Lime accumulates in its natural form, therefore, looking for any disturbance opportunity to go back to the same pattern of accumulation.
We recommend descalers for irrigation purposes, as cold water gets treated by descaling over longer periods.
Houses and other buildings do not normally use water constantly, thus making it hard for descaling to be done properly.
Descaling is a slow process and in most cases, high-intensity lime deposits will not all be treated.
Water softeners are the most effective systems to remove hardness from water and in case of a booster pump being used from the water tank to the building, a high-pressure automatic water softener can be installed after the pressure pump.
Lime is physically removed by resin from the water, then washed off and excreted during the regeneration process. Lime and magnesium minerals that cause hardness, together with the salt (sodium minerals) are all excreted during regeneration and do not go through to the building.
