But how can I get an opening out of the pipes? Do I have to cut?

: If this is a residential unit with a 3/4" PVC drain, you will not get a snake through it because the elbows will all be square corners. Use an air compressor and blow the pipe clean.

: : The floor drain of my air conditioner is clogged. Water goes through PVC pipes to the drain. Now for me to un-clog it, I need to somehow have an opening to insert the "snake."

: : Since these PVC pipes and joints are glued together (at least I think they are), how can I separate them?

: : Any help is appreciated.
