Here on the eastern end of Long Island our groundwater supply has a naturally occurring pH of 5.4 to 7.2. pH is the measure of acidity or alkalinity in a water sample, with 7.0 being absolutely neutral. As the numerical value decreases, the amount of acidity in the water increases. Water with a pH lower than 6.4 will be corrosive enough that it can literally decay the plumbing in the home and will often result in a bluish/green staining to occur in the plumbing fixtures and in your hair. Acid neutralizers installed on the main line of the home elevate the pH of the water and prevent this corrosion from occurring, resulting in protection of the plumbing and elimination of staining.
