  Excerpt regarding Application Limitations:
  
  On hardness levels of 60 grains and higher, the system may not achieve a hardness of less than 1 grain, due to high Total Dissolved Solids. (Some bleed through is possible.)
  
  Bleed through can also be caused by sodium levels higher than 1000 parts per million. In either case, your system can be programmed to minimize these effects. See your RainSoft Dealer for details.
  
  Chlorine or Chloramine levels on municipality treated water should not exceed 4 parts per million.* When Chlorine or Chloramine levels are 4 parts per million* or greater, it can have adverse effects on your system.
  
  In applications where high levels are a concern, pre-filtration is necessary to reduce the Chlorine or Chloramine to an acceptable level. See your RainSoft Dealer for details. When this system is installed on water with Ferrous iron, also known as clear water iron, the maximum range of removal is based on local water conditions.
  
  The range is generally 2 to 10 parts per million. Your equipment may require special programming, along with an additive to the brine tank, to maximize the equipment’s ability to remove iron. See your RainSoft Dealer for details

RainSoft clarifies misconceptions about water softeners

Excerpted from the RainSoft Gold Series IO Manual cited above.

Amount of Salt Added to Water Supply by at Water Softener

The most common topic of confusion is the amount of sodium (Na), not table salt (NaCl), that is added to the water from a water conditioner. In reality, ion exchange does replace the hardness ions in your water with sodium ions, but the common misconception is the amount used.

For every 1 grain of hardness, the exchange process will deliver approximately 8 milligrams of sodium per 1 liter of water. The amount of sodium present in a standard 8 ounce glass of treated water, that was 10 grains hard prior to treatment, would be around 19 milligrams of sodium.

This is an insignificant amount of sodium considering a typical slice of white bread has about 140 milligrams.

Causes of Coudy Ice Cubes

Another common misconception of water treatment systems is the idea that soft water will produce clear ice cubes. Cloudy or white, hazy ice cubes are caused by air that is slowly being released from the water during the freezing process, which has nothing to do with the performance of your system.

Amount of Salt Used to Regenerate the Water Softener

People seem to think that water conditioners use an enormous amount of salt, which may have been the case in the past, but that was due to old technology and standards. Water conditioners do use salt for regeneration, but the amount of salt varies by water consumption.

The more water that needs to be conditioned, the more times the system will regenerate, resulting in the use of more salt.

Fortunately, today’s technology allows us to dispense just the right amount of salt for maximum efficiency, based on your individual water consumption needs.
