Hard Water Problems?

Water is an essential part of our everyday life.
We drink it, wash our bodies and hair with it, clean our clothes with it, even heat our homes with it and yet we seldom pay attention to its effects. If you live in a hard water area you’ll soon know!
– Hard water causes mineral deposits to remain on the skin, hair, and clothes.
– It clogs pipes, water tanks, and boilers – reducing efficiency and increasing energy bills.
– It discolours sinks, baths, shower cubicles, toilets, and taps.
– Its deposits form limescale which reduces the effectiveness of household appliances such as washing machines.
