What Model Softener Is Right For You?

Below are some key questions to ask yourself when choosing a Kenmore water softener. Your Sears store water professional can also assist you in determining which Kenmore water softener is right for your home.

  • If you currently own a water softener, what do you like best and least about your current model?
  • Are you on municipal or well water?
    After installing the water softener on municipal water, a water test should be performed to fine tune the hardness setting on the water softener.
  • Are you experiencing any rust stains?
    Municipal water very rarely contains iron. By eliminating the concern for iron removal capacity, you eliminate the need to test the water for iron prior to buying a water softener. If you have an iron staining problem, test the water and check the iron removal rating for the water softener prior to making your purchase.
  • Is this a new home?
    Many of today’s newer homes are being built with a 1” or larger main water supply line. This requires the use of a softener with a higher flow valve.
  • How many people are in your home?
    Higher hardness removal capacity is necessary to handle high water consumption. In addition, higher water needs at a given time might necessitate the need for a higher flow valve.

The Kenmore 350 Series and 300 Series will soften the water in most of the homes in America. However, moving to a softener with more capacity will cause less frequent regenerations. This saves salt, water and money. In a short amount of time, the higher capacity water softener will pay for itself.
