My house is a Fox and Jacobs built in 78. I have, probably the original, Lennox a/c unit with the air handler over the shower. It drips. Cold water. In the shower. I know the drain line is clogged. I can feel standing water in the line at the access point just off the air handler. I have tried to snake it with a sewer snake, piece of steel wire, fish tape, blowing air through hose. What else can I try?
The snakes and fish tape wont make it around the 90 bends.
It comes out of the handler about 6 in then 90's, about 6 inches more then 90's down, from there I dont know where it goes.
I was thinking of trying drano or lots of water pressure.
