How to Test for Hard Water

How to Test for Hard Water

One of the most common plumbing issues homeowners can face is having hard water. However, not many people know how to determine whether they actually have hard water or not. While you can most definitely have your water tested by a professional, you may want to try the DIY route first. Here are a few things you can do:

Try the Soap Test

Remember: soap suds don’t react well with hard water. Take a clear bottle with a tight-fitting cap and fill it with 8 to 10 oz of water from your faucet. Then, add 10 drops of pure liquid soap and shake it up.

If the results show a lot of suds and the water below the soap remains pretty clear, your water should be decently soft. However, if there is only a thin layer of soap suds and the water below that looks cloudy, you probably have hard water.

Ask Your Utility Company

If your water comes from a municipal supply system, call your utility company or look up the water quality report online to get an idea of the hardness of water in your area. The scale of calcium carbonate in your water is as follows:

  • Soft water: 0 - 60 mg/L

  • Moderately hard water: 61 - 120 mg/L

  • Hard water: 21 - 180 mg/L

  • Very hard water: over 180 mg/L

If your water scores anything higher than 60 mg/L, you should consider taking measures to soften it.

Get a DIY Test

Head to your local hardware store and pick up a DIY water test kit. Be sure to choose one that is made by a reputable company and that actually tests for hard water. Typically, you will perform a wet-strip test and compare the color to a chart in the kit.
