American Valve CondensateRx FAQ

Why is a condensate neutralizer required for high-efficiency HVAC equipment?

High-efficiency condensing boilers and tankless water heaters produce acidic runoff (often with a pH similar to vinegar or lemon juice). Without neutralization, this water eats through cast iron drains, damages concrete floors, ruins landscaping, and harms septic bacterial balances.

How often does the CondensateRx unit need to be replaced?

American Valve recommends replacing the unit after 1 year or approximately 750 hours of boiler operation, whichever comes first.

How should the CondensateRx unit be mounted?

Mount the cartridge either vertically or horizontally below the equipment trap, ensuring a minimum downward slope of 1/4" per foot for proper gravity drainage. Always ensure a primed gas trap is installed on the drain line prior to the neutralizer to prevent flue gases from venting.

Is this unit pressurized?

No. CondensateRx neutralizers are designed exclusively for non-pressurized gravity drain applications.
