Angry condensation everywhere

My 12 old Rheem attic evaporator coil has excessive condensation regularly. Main line doesn't keep up (3/4") and pan drain is almost always flowing. Both are open! Opened housing to find a badly rusted coil (not yet leaking) and a wet insulation in the air handler. Cleaned coils/blew out with air hose, blew out drains although not really dirty. What's happening here? How do I fix?

This an Air Handler only?

Is there a trap on the drain?

Most air handler must have a trap in the drain line.. The coil is under negative pressure, and air is being sucked into the drain... with the air going into the drain/pan, the air is not letting the water out of the pan.

With a trap, it prevents the air from going into the line, and allows the water to drain out.

The drain catch area below the coil has two openings. One is to the drain line ( out to a 3/4" pipe and to the house drain, I assume??) and another to overflow into the pan below - both open. The overflow pan is collecting lots of water draining out the overflow over the front door. Not sure and cannot locate any other traps??

Please take a photo of your set up, and link us to a photo host site like, imageshack, or yahoo.
