I had some recent work performed on my TraneXB90 and the contractor pointed out that the plug for the secondary condensate drain on the Comfort Coil should be removed. He took the plug out and piped it to the pan. Tonight I walked into the mechanical room and discovered the pan was completely full of water. Water is slowly leaking out of the plug he removed.
In addition, I pulled the manual of the Comfort Coil and it appears that he actually unplugged the primary so my primary is going to the pan and the secondary is piped away. It appears the original installer was using the secondary and left the primary plugged.
So my question is, should I have him plug this back up or would simply swapping the primary and secondary resolve the problem. Is there an actual difference between the primary and secondary or are they in parallel.
Thank you !!
