What is Limescale?
Limescale is mineral buildup from hard water found in hot water appliances and household pipes. Since about 85% of American households have hard water, it is a common problem that not only leads to increased energy bills and reduced water pressure, but early appliance breakdown as well.
You may be experiencing limescale problems in your home, costing you money on both energy bills and broken appliances, if you are:
- Noticing reduced water pressure
- Experiencing a long wait for hot water
- Detecting traces of limescale in your showerhead, tub, and faucets
Visible evidence of limescale is usually confirmation of a much larger problem. If any of the above hints ring a bell, chances are your hot water appliance pipes and household plumbing pipes are clogged with mineral buildup.
How is Limescale Formed?
Limescale is formed from naturally occurring minerals in hard water: Carbonate (lime), magnesium carbonate, calcium sulfate, calcium phosphate and sediment formations. When these minerals are exposed to high PH levels, increased temperature or pressure changes, they crystallize and attach to surfaces. This is why limescale is so prevalent in appliances such as hot water heaters, dishwashers, clothes washers, showerheads, and faucets.
