White water
White water often occurs after plumbing work when the water suddenly moves in the pipes again. The white is small air bubbles, and if you let a glass of water stand, you will see that it quickly becomes clear again.
Brown water
Brown water is also typically seen after plumbing work. When the water has been standing still in the pipes and suddenly moves again, rust particles in the pipes can be swirled up and turn the water brown. This is not harmful to health, but it can discolor light-colored laundry. Therefore, we recommend that you run a tap until the water is clear again before washing clothes. If the damage has occurred and your laundry has taken on color, it is important that you do not let it dry. A wash with citric acid can completely or partially remove the color again.
Green water
Green water is a sign of a fault in your district heating system, and you should contact a plumber. The district heating water is dyed green so that you can see if it is leaking into your water. It is best to avoid drinking the water when it has been mixed with district heating water.
