According to, 85 percent of homes in the United States have hard water. The level of hardness varies throughout the country. Some states in New England have water that’s only slightly hard, while several Midwestern states have water that qualifies as extremely hard.

Wherever you live, you may want to know how to test for hard water. Hard water testing can let you know just how hard your water is (or if it’s even hard at all).

This article will cover a trio of ways to test for hard water.

Soap suds DIY test

For this hard water testing method, you’ll need a few items aside from the water itself. It requires a clean and clear glass or bottle with a top you can seal and some natural liquid soap, like castile. Fill up your clear water bottle about one third of the way full. Then take the natural liquid soap, and add a few drops to the water. You should then seal the top, and shake it firmly for around 15 seconds. When finished, set the bottle down on a flat surface and inspect the solution.

If the water appears cloudy or milky and lacks the trademark silky bubbles, then your water is likely hard. Water that is soft would create the usual feathery, soapy bubbles and would remain clear in the presence of soap. The lack of bubbles and cloudy appearance in the hard water is a reaction between the minerals in the water and the soap. If you used castile soap, your test should be accurate.

Hard water testing kit

If you’ve ever wondered how to test hard for water, you’ll be happy to know that there are testing kits specifically made for that purpose. You can buy them from online retailers like Amazon or home improvement stores like Home Depot.

They look like a pool water testing kit in that they consist of testing strips and a color chart. You simply fill a glass with cold water from your bathroom’s sink and insert the test strip for between five and ten seconds, removing it when finished. You then match the strip’s color to the accompanying chart, and it tells you how hard your water is based on grains per gallon (GPG).

Call the experts

If you’re in the market for a new water softener, many water purification companies will come out to your home and test your water for you at little or no charge. The technicians who install water softeners are usually well-versed in hard water solutions and should have the latest and best testing methods available that you might not be able to find at your local hardware stores.

If you’d rather not do that, you can call your city or water provider through their dedicated service line and inquire about a water-quality service report. Many municipalities also have their water-quality test results posted online, so you can check those as well. Keep in mind that the reports aren’t easy to read and won’t be extremely precise either.
