L-5451 Drinking Water Problems: Iron and Manganese

Iron and manganese deposits build up in pipelines, pressure tanks, water heaters and water softening equipment. These deposits restrict the flow of water and reduce water pressure. More energy is required to pump water through clogged pipes and to heat water if heating rods are coated with miner-al deposits. This raises energy and water costs.
