Condensate line runs into the crawl 2.Potable expansion tank on heat side 3. Error code for abnormal water feeder 4. Repipe exhaust and intake Repiped condensate line to condensate pump and ran tubing to laundry standpipe, replaced expansion tank, contacted Navien registered unit and they stated the abnormal water feeder was most likely due to the potable expansion tank. They recommend keeping an eye on it if it occurs again contact them. Navien stated vent terminations were proper for their unit. Tested all work and everything appears to be in working order and there appears to be no leaks at this time. Collected payment.
