Well water often contains Iron, which may stain plumbing fixtures, bath tubs, shower walls and doors. Iron can also stain sidewalks, driveways and add a metallic taste to your water. Hydrogen Sulfide may also be present, resulting in “rotten egg” or Sulfur odors. Manganese may also be a problem, leaving black spots on plumbing fixtures. Iron Zapper systems from Safeway Water remove Iron, Hydrogen Sulfide and Manganese without using chemicals in most installations.
