How to check the quality of my tap water?

    Know your water

    Would it not be nice to know what kind of water ran through your taps? The water you use every day on your skin for showering and washing, the water you use to prepare your food, your teas and coffees, and the water you sometimes drink!

    Water hardness

    There are many attributes to water but one thing we always hear about is water hardness. Water hardness is the amount of calcium and magnesium dissolved in water. This is what causes lime build up in kettles, washing machines, shower heads.

    Check your water quality

    Because the quality of tap water changes from place to place so it is important to get the right information.
