Condensate Neutralizer 101: Protect Your Drain From High-Efficiency Acid

A high-efficiency furnace or boiler drips acidic condensate. The Axiom NeutraPal raises that pH before it reaches your drain and plumbing.

Why high-efficiency units make acid

Condensing furnaces and boilers (90%+ AFUE) pull so much heat from the exhaust that water vapor condenses out. That condensate is mildly acidic — low enough pH to corrode cast iron, copper, and concrete over time, and many jurisdictions require it neutralized before it enters the drain.

What the neutralizer does

Condensate flows through media that raises the pH toward neutral before it discharges. The NeutraPal mounts on the wall, has a manual-reset float that signals a restriction, and a bypass that prevents backflow into the appliance.

A small part that prevents an expensive problem

Replacing corroded drain lines or a cracked floor drain costs far more than the neutralizer. It’s routine protection on any condensing system.

Make sure it’s genuine.
Marketplaces are flooded with counterfeit and gray-market copies of this part. Fakes fail early and void the manufacturer warranty. Every unit we ship is authentic Axiom, factory-sealed, and covered by the full manufacturer warranty.
