Neutralizers are used to ensure the pH of water is maintained above 7.0, to protect plumbing from corrosion.

➤ Untreated water enters the valve inlet
➤ Untreated water flows down through the calcite media bed
➤ The water dissolves the calcite and as a result, pH and hardness are increased
➤ Treated water flows up through the riser pipe
➤ Treated water exits through the valve outlet
➤ Media can treat a set amount of water before regeneration is needed
➤ Media consumption depends on water usage and chemistry
➤ Routine maintenance cadence strongly recommended to maintain the media level
➤ The water flow is reversed to flush any particulates to the drain line
➤ The water flow is returned to the normal direction to repack the media bed
➤ Regeneration frequency depends on water usage and chemistry

The ability of the neutralizer to correct the pH is directly proportional to the depth of the calcite media bed. Because the calcite is consumed as the pH is corrected, the level of media falls over time and must be replenished for the neutralizer to continue to function.
While they are not iron filters, depending on the type of calcite used, neutralizers can remove some precipitated ferric iron from the water.
There are different grades of calcite on the market. The grade used can affect how well the pH is corrected, as well as how well particulates (iron) are mechanically filtered.
Comprehensive water testing is key to determining effective treatment for your water.
