You can do a quick and easy test at home to check if your water is hard or soft using a litmus paper test strip. Here’s how:

✅ What you’ll need:

  • A litmus test strip - buy yours here!
  • A clear glass or cup
  • Tap water from your kitchen or bathroom tap

💧 Step-by-Step Instructions:

1) Fill the glass with water

  • Use cold tap water
  • Fill about halfway (enough to dip the strip fully)

2) Dip the test strip

  • Take one litmus strip from the pack
  • Dip it into the water for the time recommended on the package (usually just a few seconds).

3) Wait and compare colours

  • Remove the strip and wait a few seconds as it changes colour
  • Match the strip’s colour to the colour chart provided with your test kit

4) Read the result

  • The colour will indicate your water’s pH level or hardness range, depending on the strip type
  • Many hardness test strips show results in parts per million (ppm) or grains per gallon (gpg)

🧠 What the results mean:

Hardness Level Grains Per Gallon (gpg) Water Type
0 - 3 0 - 50 ppm Soft Water
4 - 7 50 - 120 ppm Moderately Hard
8 - 10 120 - 180 ppm Hard Water
11+ 180+ ppm Very Hard Water

    💡 Tip from us:

    If your strip shows 8 gpg or higher, you likely have hard water – and it may be time to consider a water softener to protect your plumbing, appliances, and skin
