Aah. Diluted bleach solution. That sounds more plausible. The A/C guy
we
have been using just said to pour some bleach into where the line joins
with
the condensor unit. Sooo... At what ratio should I dilute standard
Clorox
bleach to get properly diluted bleach solution? Should I look for a
particular Ph?

Many, many thanks.

The dilution details are printed on the label of the bleach bottle. 3/4
cup bleach to 1 gal water is the strongest solution listed and is
certainly diluted enough not to harm PVC pipe or even a galvanized
condensate drip pan.

Well I will be damned. The lable does indeed have such instructions.
Thank you Pete. I do appreciate your patience and persistance. Now I
just have to install the fitting that will let me introduce the bleach
solution. But you have helped dispell some myths and misgivings which
were based on unsound reasoning.

Take it easy...


I've had my A/C system since 1973......Fortunately, I have access to the
condensate drip pan via what was previously the location of a humidifier.
At the beginning of every summer season I remove the cover plate and pour a
mixture of bleach and water in the pan ....don't ask since I never measure
it........well, maybe it's approx a 3 parts water/1 part bleach....... I
use at least 3-4 qts and/or keep pouring until I see a steady, fast drip out
the (outdoor) drain line. Based on the "never had a problem" results, it
does the job.
