CheckItOut Posted July 21, 2010 Report Share Posted July 21, 2010 Just curious if anyone knows when a condensate overflow pan was required with an air handler in attic or interior closet. Inspected a 1994 house with no pan and I could not tell where one had been nor did I see evidence of a second drain line. Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted July 21, 2010 Report Share Posted July 21, 2010 I would be reasonably safe in saying that most manufacturers have always recommended drain pans under the EVAP coils of unit placed in attics over living spaces or in hall closets where a leak could possibly damage property. Manufacturers seem to be a tad more stringent that the code folks in many instances. Link to comment Share on other sites More sharing options...
CheckItOut Posted July 21, 2010 Author Report Share Posted July 21, 2010 True. My 2004 house did not have a condensate drain line in the attic plumbed directly outdoors. Primary line dumped into overflow pan which drained through a pipe above a second floor window. This then dumped water on top of the main electrical panel. No idea why original owner left it like this - could hear water dripping all night long in the master bedroom as it hit the panel. Link to comment Share on other sites More sharing options...
