The JJM ALKALINE k300r is a pH neutralizer pellet refill designed for use with the K-300 inline acid neutralizer unit. These neutralizer rocks work by dissolving slowly in acidic condensate or water flow, raising the pH to levels that meet drain discharge requirements. The refill is an essential maintenance item for any installation where the K-300 unit is in service. HVAC technicians and plumbers servicing condensate neutralization systems rely on this refill to keep the neutralizer operating effectively between service intervals.
This refill is suited for residential and light commercial applications where condensate from high-efficiency gas furnaces, boilers, or air handlers must be neutralized before entering a drain system. The pellets are replaced on a scheduled maintenance basis, typically when the existing media has been consumed. Proper refill intervals help prevent low-pH condensate from corroding drain lines and violating local discharge codes.
Designed as a direct refill for the K-300 condensate neutralizer unit.
Installation and refill should be performed by a licensed HVAC technician or plumber. Before servicing the neutralizer housing, shut off the condensate source and allow any residual flow to clear. Open the K-300 housing per the manufacturer procedure, remove spent media, and reload with fresh pellets. Follow all applicable local plumbing codes regarding condensate discharge pH requirements.
