Acid Water Stains, Low pH Water
Acid Water is easily identifiable by the blue-green stains on plumbing fixtures. It eats away at faucets, fittings, and pipes, as well as corrodes water-using appliances. This water will be more aggressive than water with a "balanced pH". Soft metals such as copper pipes are at risk with low pH water.
The "blue green" stain is from oxidized copper from your own plumbing. It is very important to balance the pH of your water to keep you from having costly plumbing repairs. It is recommended that your pH be above 7 to prevent these types of issues. There are a number of methods for elevating the pH of your water, so use the form above to consult your Local Culligan Man to determine what will work for you.
