Nice return Plenum !
I called the dispatcher to find out where my next job was, she had me call the sales manager, who told me he had a job where a new customer had an air-handler in the attic with an aux drain pan and that was it. The drain had clogged, the pan over-flowed, and the customer had a mess. He had the install crew add a drain line to the pan, tie it into the primary drain and install a float switch. Just needed me to come by and wire in the switch. This is what I found:

Nice return Plenum !
Ahhh... The good ol' reverse condensate drip leg. I think they absorb water hammer from the tray/pan, you know, when the blower starts.

Not sure why you'd put a ball valve in the drain pan line, but it's closed.
Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.
ball valve makes a good coupling...... need to open it though. .... who does this stuff......
it was working.... played with it.... now its broke.... whats the going hourly rate for HVAC repair
cut off switch supposed to be in main drain line. Need a vent for negative pressure. Who knows why the valve was put in
Its a little hard to see, but there is a weep hole between the drains in the air-handler, so it will likely fill up the pan before it will trip the float. Also like firecontrol said, the ball valve is closed, which we normally put one in when we have a common line for the primary and aux drain pan so that if the drain pan fills up it will trip the pan float switch letting you know you have a problem, except there is no pan float switch. (once you fix the problem you open the valve and empty the pan). Basically they did all this work and accomplished absolutely nothing. The unit could still leak through the weep hole, fill up the pan, and overflow since the valve is closed and no pan float. At first I laughed, then I cried when I realized I had the same shirt on they did. Also there is a cap on the vent after the trap, but that was probably pre-existing.

Why not just float the safety pan and be done with it?
I think the saddest part is they couldn't wire in the switch themselves . . Not saying anything about you, just saying . .

Where are you suggesting, "A vent for negative pressure.

I didn't write the book I just read it!
Probably a refrigerant leak in the rusty evap coil too.
