A water softener will remove the hardness minerals (calcium and magnesium), dissolved iron, and manganese. Even though the EPA has no published limits on these, they can have damaging affects on your home’s plumbing distributions system and water using appliances. Hard water interferes with many cleaning tasks, from doing the laundry to washing dishes to taking a shower. Washing your hair in hard water may leave it feeling sticky and dull. Dishes and glasses get spotted and a film may build up on shower doors, bathtubs, sinks and faucets. Clothing can look dingy and feel rough and scratchy. Hard water can also cause a residue to build-up in pipes that can lower water pressure.The EPA maximum allowable level for iron as a secondary contaminant is .3 parts per million and for manganese is .05 parts per million. Small amounts of these minerals can create very noticeable, even devastating affects on your home’s water quality.
A water softener is effective in removing dissolved forms of iron & manganese and hardness minerals. To remove particulate forms, water filtration utilizing a cartridge filter with proper micron rating will be effective. Selecting the appropriate micron rating and style of filter can be determined by a water treatment professional based on water test results and other symptoms. For more information on Iron and Manganese, see our published articles in Water Technology Magazine at the following link: http:/publications/.
OTHER AFFECTS OF HARD WATER, MANGANESE & IRON
Hard water scale (see photo below) can build-up inside water heaters insulating the temperature sensor inside the tank creating extra work to bring the temperature up to the set level. This reduces the life of your hot water heater and will most likely require early replacement. Some other affects of these contaminants include corrosion and scaling inside pipes and major staining throughout the home’s showers, bathtubs, and sinks.
