This is my first post on here, not counting the intro I just posted, and I'd like to say first that I think it's great that there's a forum like this. I've used one for RV's, mechanical help on my car, injury problems from work and running, etc, etc, and I'm glad I found this one.
I've got an AC condensation drain problem that I need (want) to fix before we fire up the AC this summer. The installer did a great job with the hvac and ductwork on this hundred year old house (it never had central anything), and the system is hung from the floor joists in the old basement. It's condesation tube is coming from the side of the plenum just coming out of the heat\ac unit (horizontal install), but the plenum is now a little lower than the drain opening, and over the years has started dripping steadily from the bottom 'pan' of that plenum from what looks like a corroded or busted off head of a hex head sheet metal screw that holds the plenum bottom to the side. (I will go take a picture of it in a minute, but my wife said I have to clean the refer and the freezer, vacuum the house and wash the dishes first.)
The question is two fold. I know how to make the hole in the bottom, lower part of the pan, but what is the proper connection for a water tight fitting to connect to a 3/4" id pvc drain pipe through the sheet metal. It has to be low enough to let the water escape. This would make the original the over flow outlet.
Secondly, I was told that there is a pump that would allow me to pump the condensation up and across the joists and allow me to drain it outside, instead of into the sump pump in the floor. This house is built on what seems to be rock (this area is solid sandstone), and the basement is the old, damp type that were built back in the early 1900's, so it really doesn't need any extra humidity down there, anyway. (Our humidifier runs most of the time in the summer, or after a few days of rain, which trickles in and makes its way to the sump. Anyway, my two questions are, how to make the connection for a re-route of the drain tube, and then, --- what and how is the "condensation pump" that would remove it from the basement totally. Thanks for any and all ideas or comments about this task that I am about to intrepidly undertake.
