Limescale causes chalky white stains and marks on fixtures; due to minerals building up in the water as it travels. While scale is obvious on shower doors and fixtures, it also forms in places you cannot see. Common problem areas include water pipes and hot-water-using appliances such as a water heater and dishwasher.
Reduction in Efficiency
Limescale can build up in water and heating pipes, leading to a reduction in water flow and pressure. Appliances have to work harder, resulting in premature wear and higher maintenance costs
Dries out skin
Limescale is a result of hard water, which leads to irritation in sensitive skin, causing it to become dry and irritated. It may also trigger eczema for some individuals.
