Water Leaking

Water softeners that can be used to minimize the effects of hard water around the home...including the pros and cons of each and the potential health issues that arise.

Chemical Water Softeners

This is when specific chemicals are added to the water to control water hardness.

The types of chemical that can be used include washing soda and borax. These chemicals form an insoluble precipitate with calcium and magnesium minerals in the water. The mineral ions then cannot interfere with cleaning efficiency, but the precipitate makes the water cloudy and can build up on surfaces. The disadvantage of precipitating water softeners is that they can increase the alkalinity of the water and this may damage skin and other materials being cleaned.

The second type is non-precipitating water softeners use phosphates to collect calcium and magnesium ions. There is no precipitate that is formed and alkalinity is not increased. If used in enough quantity, non-precipitating water softeners will help dissolve soap scum for a period of time.

Mechanical Water Softeners

These are devices that can be permanently installed into the plumbing system to continuously remove calcium and magnesium.

They operate on the ion exchange process in which water passes through a media bed, usually with resin beads that are supersaturated with sodium. The ion exchange process takes place as hard water passes through the softening material. The hardness minerals are collected by the beads while at the same time the sodium on the resin beads is released into the water.

When the beads become saturated with calcium and magnesium, they must be re-newed. The recharging is done by passing a salt solution through the beads. The salt solution which contains sodium replaces the calcium and magnesium minerals in the water which are flushed away.
