Any recs. on how to keep algae/? from building up in a/c condensate drain
line. I have used bleach on a regular basis in the past but was recently
told by a/c repair type that they have noticed that this can damage the pvc
pipe. He suggested using vinegar but thought that works fine for lime
deposits but what about algae! Thanks. Art
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.
atlas a/c had written this in response to
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.

And if you read further its applying to soft absorbant building
materials, it states that in a few days it will come back worse, that
is a total bullS statement. It also states removal of the molded
product is best. No, stopping the moist enviorment is best. Ive used
it on certain shaded concrete areas for years and i can keep it mold
free with a yearly spraying. Just because its posted on the web you
think all you read is true? This BS post, was likely put together by
mold remediation companies suckering people into demolition,
demolition without even addressing what caused the mold in the first
place, remove excessive moisture and mold becomes inactive and dies.
Of course you didnt see it says Hard Surfaces are ok with bleach, just
as PVC and AC systems are hard and nonporus. Read between the lines
on that bs site, I guarntee Bleach kills mold, by removing its oxygen,
it only comes back because the environment that caused it remains the
same. Mold Spores are everywhere, airborn.
Not that I'm doubting what they (or you) say, but why should I believe
MoldAcrossAmerica over the Centers for Disease Control?
And this doc lists some sources that recommend using bleach (including
the CDC), along with some sources that suggest other remediation
It appears that there is a grey area between bleach being used to get
rid of the mold and it being used solely to disinfect the area after
the mold has been removed by other means.
All paint manufacturers have for at least 30 years recommended bleach
to kill mold before painting, its industry standard and works. These
jerks probably sell other chemicals or talk people into removing
building products rather than restore them from mold damage. a hack
