Hard water interferes with almost every cleaning task, from doing the laundry to washing dishes to taking a shower. Washing your hair in hard water may leave it feeling sticky and dull. Hard water can also cause a residue to build-up in pipes that can lower water pressure throughout the house. Clothes can look dingy and feel rough and scratchy. Dishes and glasses get spotted and a film may build up on shower doors, bathtubs, sinks and faucets. Calcium and magnesium can have devastating affects on your home’s plumbing as well as your ability to clean, even though the EPA has no published limits on these. The EPA maximum allowable levels for iron as a secondary contaminant is .3 parts per million and for manganese is .05 parts per million as secondary contaminants. Small amounts of these minerals can have very noticeable, even devastating affects on your home’s water quality. Water testing can determine the best approach. A water softener will greatly improve your water if you have iron, manganese or hard water minerals present in your water. These contaminants found in Dover water can be removed with a water softener and/or a properly specified sediment filter depending on whether their forms are particulate or in solution.

OTHER AFFECTS OF HARD WATER, IRON & MANGANESE
Scale from hard water 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 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.
WHAT WILL A WATER SOFTENER CORRECT
A water softener is effective in removing dissolved forms of iron & manganese and hardness minerals. To remove particulate iron or manganese, a cartridge filter with proper micron rating will be effective. Depending on the specific situation, this could require a series of filters with different size micron ratings to handle heavier levels in the water. 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.
