how do you unplug an ac over flow hose?

Answer 1

First try puring a 1/4 cup of bleach into the line. you should do this periodically to keep the line free of mold. If this doesn't work you can use an electricians tool used to pull wires through walls call a fish or if you have an air compresser you can blow it out. Be careful if using air pressure wear safety glasses and don't use too much pressure.

Answer 2

my tech takes a garden hose with a screw brass sprayer on the end. puts a man in the attic and he forces water up the pipe and the other guy lets him know when he sees water. if need he will take a air tank in attic and force air down toward outside to flush after water is used.
