In the U.S. about 85 percent of the homes have hard water. What is it? If your water contains too much dissolved calcium and/or magnesium, you have hard water. But how can you tell?

Difficulty: Moderately Easy
Instructions
  1. Step 1

    Look for clues that your water has an overabundance of minerals: Dishes will have water spots on them, your soap won't lather well, your white clothes will look dingy. You may also notice white, crusty sediment on your fixtures, a recurring bathtub ring, or rust-colored stains on your clothes, silverware, or porcelain fixtures. The not-so-obvious results of hard water are serious wear and tear on your water-dependent appliances.

  2. Step 2

    Contact your municipal water supply, or local department of health to direct you to a lab that will test your water hardness.

  3. Step 3

    Avoid home tests, which are expensive and have a tendency to be inaccurate.

  4. Step 4

    Call a water conditioning company such as Culligan to come to your home and test the water. You may have to listen to the sales pitch for a water softener, but the test is free.

  5. Step 5

    Look at your test results. If the water hardness is above 1 GPG (grains per gallon), your water is hard. (See Glossary)

  6. Step 6

    Consider mechanically softening your water if the test reveals a hardness of more than 3 GPG.

Tips & Warnings
  • Remember that if your water contains high levels of sulphates, iron, or chlorides, you may need a purifier as well as a water softener.

on 11/20/2008 Before even putting in a water softener, you should consider whether it will even benefit your health vs the "hard" water. Long term studies reveal that by consuming soft water for a long duration of time, leads to an increased wrisk of cardiovascular disease.

I'm currently a molecular and microbiology student and from a recent lab I conducted, I found that (as stupid as this may sound) it would benefit you most to bathe, wash dishes, ect with soft water and leave hard water to drinking.

on 11/22/2005 People should know that your water is a very important thing. You just cannot put in a water softener and hope that it cures all your problems. It would be more advisable to have an expert look at your water and do the job right, and safely.
