Blue Stains
Blue stains on fixtures are caused by the action of our water on copper, usually from newer plumbing systems. Copper dissolves into the water when water sits in the pipes overnight or is unused during the day.

Running the water for 15 to 60 seconds, or until there is a change in the water temperature or smell of chlorine, should help. Keeping the fixtures dry and drip-free also helps solve this problem.

We began operating our new corrosion control plant in June 1997. The plant ensures that dissolved lead and copper levels are well within drinking water standards and should reduce problems with blue stains.

Pink Stains
Bright pink stains on fixtures, drainboard surfaces and pet dishes are caused by the interaction of oxygen in the air with dissolved rust, resulting in an iron hydroxide precipitate on the surfaces.

Running the water for 15 to 60 seconds or until there is a change in the water temperature should help. Keeping the surfaces dry also helps solve this problem.

Pale pink stains or black-gray stains around bathtubs or showers may be a form of mildew. Again, keeping the fixtures dry will help reduce the problem.
