Very big misconseption, bleach does not kill mold, it antagonize's it! It
may visably go away for a while but it will come back 3X as bad. Bleach
is heavier than water, so it can't get out of the line at the P- trap.
(The part sticking out of the ground outside.) So it will slowly damage
the PVC pipe and also solidify and cause a blockage. Put a cup of White
Vinegar in you line every month to three months through your
safe-t-switch,or an access Tee you may have in the line or seperate the
pipe at the point your A/C tech made in your line and coupled with vinal
tube the last time your line backed up and they cleared it! Plus, if you
spill vinegar on you or around your unit, it will just smell like a salad!
Or you could be Pro- Active and purchase a $30. Stinger shop-vac at your
local home/hardware store and 2 or 3 times a year put the suction end of
the vacuum on the exit side of the pipe outside and let it run for 5 to 10
minutes. If the hose is doing a small dance, your clear. if it is not, you
may have a blockage and will need to force air from the air handler side
out while the vacuum is running.

Bleach does kill mold and algae, I dought bleach is really going to
make a difference to the pvc since its not under pressure and its only
temporarily in the pvc. After maybe 30 minutes flush with water.
