Frequently Asked Question ("FAQ")

Q1: How often should I replace the neutralizing media?
A1: Once per year, using pH test strip paper or an electronic pH meter, check the pH level at the outlet of the neutralizer tank. Replace the neutralizing media when the pH level drops below the minimum level specified by the local water authority. The minimum level is commonly set at pH 6.0.
