Brown or discolored water is caused by minerals, sediment, or rust that may accumulate in the water mains over time. When the water from your tap is brown this indicates a disturbance in the water main that stirs up these deposits.
But it is possible to have both mineral rich hard water and iron rich water, causing a combination of hard water calcium and magnesium buildup and unsightly brown iron stains. Both can be tough to clean.Your rust stained clothes, fixtures, sidewalks, driveways, and walls are not a lost cause.ven though they look like rust, they maybe be caused by iron-rich water.
