When it rains, the water falling from the clouds is completely soft, it is
not until the rain hits the ground that it begins to absorb minerals such
as calcium and magnesium found within the earth. These minerals,
whilst natural, create scale build up causing hard water damage
throughout your home.
Granite areas are so hard that water cannot permeate through it, so
rain water will simply run-off the surface and not absorb any minerals along the way.
Naturally soft vs softened water
If you’ve been to Cornwall, Wales or Scotland you may have
experienced naturally soft water. Softened water is much softer than
naturally soft water.
