What does yellow water mean in practice?
If the water turns yellow only after standing, a common cause is oxidizing iron; the color in only one tap rather indicates the installation.
When does it matter?
The problem may cause stains, unpleasant taste and deposition of contaminants in fittings and devices.
Which solutions are related to it?
Raw and tap water should be compared and iron, manganese, color and turbidity should be tested before selecting the technology.
