re: A/C drip pan full. Bleach down PVC drain pipe?

When we had ours installed, I had the crew attach the condensate drain lines with a screw together union. When ours stop up, easy to unscrew blow out and screw back together. Shouldn't be to hard for you to cut the pipe, blow out the line and put it back together with a screw together union. Also had my pans under the units plumbed to the eave by the driveway. If I see water dripping there, I know the drain line is stopped up, but I don't have to worry about the unit cutting off.

I used to go put about a cap full of bleach in a few times a year, before the units were changed out with the unions.
