🔬 Why Test Water Hardness?
Over 60% of UK households live in hard water postcodes, with many areas reaching over 250 ppm on the hardness ppm scale. Hard water causes limescale, scaling, appliance wear, and skin irritation. If you have hard water, a water softener is the best way to permanently remove it. Soft water can help you to:
-
Protect washing machines, dishwashers & kettles
-
Reduce limescale buildup in pipes
-
Improve soap & detergent performance
-
Protect your skin, hair, and laundry
-
Save money on repairs and energy bills
