Rust stains are the red rusty markings left on the sides of your tub or sink where the water hits the sides.  Inside your laundry or appliances.  It can be rusty stains on the outside wall of the house from an outside tap.  

This can be caused by high iron or manganese levels in the water.  Depending on the levels we recommend a water softener for lower levels, and an Air and Sand filter for higher levels.

If you have green or blue staining – indicates the presence of copper – so most likely have acidic water and it is leaching your copper or brass fittings. Sometimes the water source has copper in it and should be removed for health and safety.

  • Acidity can be treated by adding calcite in a cartridge in a Big Blue.
  • Copper removal may require a Reverse Osmosis
