If you see stains or buildup on your sinks and bathtubs…if you need to use huge amounts of soap to clean dishes or wash your hair…or if your water tastes or smells odd, you more then likely have hard water.
If it is not treated, the minerals in your hard water will cause yellow stains on plumbing fixtures and be deposited as scale, eventually clogging plumbing and shortening the life of appliances like washing machines, water heaters and dishwashers. Scale deposits not only cut down on the efficiency of these appliances, they cost you money, increasing both energy and maintenance bills.
