Protecting Properties



The effects of untreated acidic condensate can develop quickly, corroding copper or iron pipes or floor drains in a matter of months, not years. Fortunately, condensate neutralizers are relatively inexpensive, and they can save property owners from expensive damage. 

Condensate neutralizers are quick and easy to install, during the initial installation or annual maintenance of high-efficiency, gas-fired appliances. Neutralizers should be installed by a licensed, trained Installer or Service Technician.

Condensate Neutralizer Maintenance

JJM® condensate neutralizers must be routinely serviced to remain effective. Once a year, Service Technicians should inspect the neutralizer and replace the JJM® pH Power Pellets® (neutralizing media) to ensure continued protection and code compliance.

When you register a JJM® condensate neutralizer, the neutralizer will be under warranty against defects in materials and workmanship for one year. The warranty does not cover the issues that result from misuse, improper installation, and/or failure to replace the pH Power Pellets® as instructed.
