High-efficiency condensing tankless water heaters produce gallons of acidic water vapor every week. If the internal condensate siphon trap clogs with sediment, or if the external drain line freezes or sags, acidic water backs up into the secondary heat exchanger. This triggers float switch lockouts (such as Navien E029 or Rheem Code 29) and can corrode internal fan motors. In Flossmoor, Illinois, our technicians clear condensate blockages, flush internal siphon cups, replenish calcium carbonate neutralizing media, and install heated discharge lines.
