Transcript:Test for Hard Water

Hi, I'm Debbie Anderson for About.com. Having high mineral content, also known as hard water, in the home is one of the most common water treatment problems found in the home. So, today I'm going to show you how to quickly test for hard water in the home.

What You Need to Test for Hard Water

For this task, you will need liquid dish soap and an empty 16 ounce water bottle with a cap.

Mix Water with Dish Soap

First, turn on the tap water faucet to the sink and fill up the empty water bottle with just about a half a cup of tap water, which is about a quarter of the way up the 16 ounce size water bottle.

Next, add 10 drops of liquid dish soap to the bottle, and then tightly screw the bottle cap onto the top of the water bottle. Briskly shake the bottle of soap water for approximately 30 seconds.

If Foam Forms Quickly, No Hard Water

If the soapy solution inside the water bottle foams up quickly, then you most likely do NOT have a hard water problem in your home.

How to Tell if You Have Hard Water

However, if the soapy solution inside the water bottle does NOT foam up quickly, and instead creates a milky-curd-like or soapy film on the water, then you most likely DO HAVE a hard water problem in the home.

Finally, if you believe you might have a hard water problem in the home, look for hard water scale build up on your bathtub or shower, or look for white scale build up on sink faucet aerators, because this is another indication that the water is too hard in your home.

And with these quick and easy tests to see if your home has a hard water problem, you're sure to know when it's time to treat the water in your home without wondering. Thank you for watching. To learn more, please visit us on the web at About.com.
