Water Softening, an Overview

A water softener is used to soften water. What that means is that it removes the chemical elements, generally ions, that make water become hard.

The main ions that cause issues are magnesium and calcium. These ions can get into water as it flows through pipes.

What hard water can do is leave deposits on things, like a film after taking a shower, or spots on dishes that were washed. Additionally, it can make your heaters work slightly less well, which can increase heating costs.

These systems basically work by exchanging ions it contains, generally sodium, or salt, with the hard calcium and magnesium in the water. It does through a diffusion process that occurs as water goes through it.

What it consists of

A softening system consists of a water softening tank, which contains minerals, beads and appropriate internal mechanism. Additionally, it has a brine tank which is used for storing brine and salt.

Finally, there is also generally additional elements such as an electronic monitor and control interface to allow gauging of the water and controlling of activity.

Concerns

They tend to be somewhat expensive, with standard models coming in at around 0-700. They also tend to require a somewhat detailed installation process, being hooked up to the right water pipes.

Additionally, some people are concerned about the sodium that is added to the water, which can cause issues for some with health issues.

The magnetic controversy

Magnetic water softeners work by using magnetic fields to affect the balance of the water. They don't require as significant installation and don't add sodium to the water. As such, they have attracted some audience since the 1930's.

The problem? Professional engineers and water specialists are not convinced that they work so well. They argue that it may technically be impossible to magnetize water. Additionally, some plumbers agree that magnetic water softeners do not work.

Potassium vs sodium salt

Another option some people consider is to use potassium instead of sodium for the replacement.

The reasons for doing so generally are to reduce the sodium content in the water that can come from this process. In general, this isn't so much of an issue, but for some, especially those with health concerns, it may be an issue.

The benefit of doing can also mean that the waste product of the softening is more environmentally friendly. In some cases, it even has potential as a fertilizer.

The downsides include cost and potential taste change to the water.
