If sewage managed to make it's way into the condensate line, then the problem is twofold:
1) The condensate drains should have been plumbed to a trapped indirect drain or floor drain with a minimum of a 1" air break between the outlet of the condensate drain and the inlet of the indirect receptor/floor drain -- Condensate drain lines should never be piped directly into a waste line.
2) If sewage managed to enter the condensate drain, then it could only have done so if a drain line had backed-up.
