When you have hard water, you are dealing with two primary problems, which are easily corrected with the use of a water conditioning system. The first problem is the formation of hard water scale on plumbing fixtures, in pipes and your hot water appliances, such as water heaters, washing machines, dish washers and coffee makers. The second problem occurs because soap, detergents and shampoo do not completely dissolve in hard water, leaving a film on shower doors, walls, your skin and in your hair. This results in bad hair days, dry skin and extra work to remove soap curd form surfaces and glass shower doors.
