Water Softener Buying / Rental Guide

Our Water Softener Rental / Buying Guide will help you determine the most appropriate type of soft water rental for your home.

The water in your home may, or may not, be hard. If you are unsure whether you have hard water, Culligan Water offers a free in-home water test to help you determine the exact level of hardness of the water in your home. There are many types of water softeners on the market, including whole-house water softeners, single tank water softeners and dual tank water softeners. The type of water softener you rent or buy for your home will largely depend on your overall water usage, hardness level, and whether any additional contaminants exist in your water supply.

Measuring Water Hardness

Before you can determine the appropriate soft water rental or purchase for your home, you need to get a measurement of your water hardness. There are multiple ways to measure water hardness levels. Commonly used units of measurement include milligrams per liter (mg/L), parts per million (ppm) and grains per gallon (gpg).

Water with less than 17 mg/L of total hardness is considered soft. Water with 17-120 mg/L of total hardness is considered slightly-to-moderately hard. Water with over 120mg/L of total hardness is considered hard, and anything over 180 mg/L of hardness is considered extremely hard.

Types of Hard Water

Dissolved magnesium and calcium salts are most commonly associated with hard water. However, hardness can also occur when anions in water combine with soluble divalent metallic cations, such as: aluminum, manganese, iron and zinc. Depending on the chemical makeup of the hard water compounds, there are two types of water hardness: carbonate and non-carbonate. Total water hardness is a measurement of the amount of both carbonate and non-carbonate hardness compounds. Culligan water softeners can effectively remove both hard water compounds from your water supply.

Hard Water Problems

When heated, hard-water minerals that are dissolved in your water can recrystallize, forming scale. This scale can:

In addition, calcium and magnesium react with soaps and detergents, diminishing their lathering and cleaning capabilities, and leaving behind soap scum residue.

While evidence does not suggest that drinking hard water poses any negative health effects, iron and manganese – if present in hard water – can give your water an undesirable taste and bad odor.

Buying or Renting Water Softeners

In addition to your water hardness level, you will want to look at your family's water usage and needs before deciding on a soft water rental or purchase. You will also want to study the individual specifications of each water softener on the market, for example:

Culligan offers whole home and dual-tank water softeners that allow for continuous soft water without interruption.
