This is a system that is used to adjust the pH and to increase the general Hardness / Alkalinity of the water to manage Corrosion and acidic water-related issues. These systems are typically used when the water is corrosive and the water is causing chemical corrosion of the household piping resulting in increased levels of copper, chromium, nickel, lead, zinc, and other corrosion by-products.

Neutralizing filters can be used where the raw water pH is 6.0 or greater. A limestone medium will raise the pH to only about 6.9 to 7.0. If a higher pH is needed, a magnesia filter medium should be used. For waters with a pH of 4.0 to 6.8 a soda ash (sodium carbonate) medium with a chemical feed system is typically used. The soda ash is usually fed into the system at a rate to produce a pH of approximately 7.0. When the raw water pH is less than 4.0, a caustic soda (sodium hydroxide) solution is used.

Note - Solutions of sodium hydroxide are extremely caustic and should only be handled by trained individuals.

Follow the Path to Clean Water

We recommend that, prior to installing a CounterTop POU (Point-of-Use) Unit, you Get Informed by gathering as much information as possible and Get Tested by conducting multiple levels of testing depending on your needs: Level 1 Observational Testing using our Self Test Web App, Level 2 Do-It-Yourself Testing, Level 3 Informational Lab Testing and, if needed, Level 4 Certified Testing conducted by a water professional.
