AC condensate drain unplugged by blowing air backed up washing machine water
My condensate drain for my attic ac unit was clogged it runs down into the floor drain the hot water heater uses in the garage closet I found the blockage by feeling the pipe for the cold water and when I got to a spot that was warm I cut into it and blew air through it. Apparently the washing machine was runnig at that time and I heard a big gurgling noise from the air and all of a sudde and the washing machine backed up through the floor drain and made a mess. A few minutes later it happened again so I pulled the condensate line out of the drain and sucked the water out with a shop vac to break the suction but have been to scared to try it again to see if it worked. What did I do with the air and how do I fix it? Thanks
