My air conditioning unit was leaking a lot of water from the AC Drainage Pipe. This is a cause for concern because it typically means your main line is plugged. If your main line is plugged water is flowing into the overflow and draining out of your backup line. The AC Company I called was going to charge me about 0.00 to drain my clogged line. It only took me about .00 and 1 hour of my time.
Here is what I needed to fix my line:
A hacksaw to cut my PVC pipe
PVC Cement from a hardware store to glue the pipes together
A coupling from the hardware store
A bucket to catch any water
A towel to clean up any water
Air Compressor to blow out any clogs / You could substitute with a Wet Vac
