Found this in a previous thread relating to the copper line failures which explains why vinegar which has acid may be a problem. Extending the drain out away from the AC unit seems to be is a good idea also.
ALSO Do not under any circumstances use vinegar to flush the condensate line. The AC copper lines are enclosed in conduit along with the condensate line and IS NOT PROPERLY SEALED. After digging up 6 abandoned underground lines, we found them sealed with publix shopping bags, pepsi cans, roofing, and bubble wrap. I'm not kidding I have the pictures to prove this. The Vinegar is 5% acid and will seep down to the exit of the copper lines and copper and acid don't get along. DUH !
I actually suggest you extend the condensate line away from the compressor area. Other wise this area is constantly moist.

Air Conditioning Failures (HVAC) |
I assume this applies only to houses where the copper lines and condensate line are together in a conduit under the slab. Some houses have the copper lines run up the outside of the house and in through the attic and down into the air handler. This is the case in some instances where older units are replaced. The condensate line remains in the under slab conduit so any leakage would not effect working copper lines.
I believe there are other problems with running the copper lines through a conduit under the slab.
