A build of up of limescale can reduce water flow in taps and pipes, bathtubs and sinks. It can also prevent heat transfer in kettles and can be an annoyance that will keep occurring if you don’t take the proper steps to remove them. hard water contains high number of dissolved minerals such as calcium and magnesium carbonate and is formed when water percolates through deposits of limestone, chalk or gypsum. Hard water has a moderate health benefit but poses a critical problem in industrial settings on pieces of equipment which handle water boilers and cooling water. A common magnesium mineral is a dolomite (which also contains calcium). Rainwater and distilled water are soft because they contain few ions. According to World Health Organization report they indicated that “there does not appear to be any convincing evidence that water hardness causes adverse health effects in humans, In fact, the United States National Research Council has found that hard water actually serves as a dietary supplement for calcium and magnesium.
