I used to wonder about my old AC drainage on to the roof. I even tried to ream out the drain hose. When I replaced the AC last year I discovered I had an aftermarket AC that was never set up for the drain. I put a Coleman Mach 1 in (12500 btu). It is not set for drainage into the tube. After some condensate showing up by the door I realized this would need to be remedied.
I thought I had it done by draining the inside pan--WRONG! There are two drain points on the Coleman. I will need to mark the roof at both drains, pull up the AC (may have to buy a new gasket when I do that), drill two holes, run a tube to each drain, make a connection, T the two drains then hook up the drains. In additon to grommets and sealing the hole it should be a piece of cake
I am not looking forward to this. I still wonder how much the bead ofsikaflex I ran over the awning rail had to do with the channeling, when I removed the bead, water went through the rail and ran down the side as it had in the past. Probably time for some Acyl-R in all of the seems.
A bit off subject, you can skip this part (rant)--- but I just saw the news as I write this, and two articles stood out----1 Big manufacturers hiring illegals, and 2 the kids coming back from the war are well over 11 % unemployed. A significant number though not all, businesses - sure don't mind making these kids pay for their businesses right to operate, but the kids are then garbage when they want a job. An illegal will help corporate profits. A Vet especially an injured one; vs corporate profits---sorry vets but the million dollar VP bonus is far more important... Makes me sick! I see some of these kids at VA, many of them will keep on paying for others---for the rest of their lives. To those that have the opportunity, please give one of these kids a break (I should not say kids, but I am over 60 so give me that break)
I noticed this news more than some because I just had two discs removed (third cervical spine operation---second that is a two procedures for one slice) due to an old service injury that deteriorated more and more over time---this time I got some titanium armor! I am not a hero or anything like that---I got hurt stateside -- just that a bad day in the airborne, tends to be a really bad day, thankfully most of those days were very good days.
I know I will get my Airstream flagpole brace replaced so I can once again-fly the flag Inland Andy gave me.
Back on subject--I apologize to those that are offended by this sort of rant as it is out of place as well as off subject - something of the moment - and will not happen again.
When installing an AC, investigate the drains location so you can fabricate a connection.The drain hose is there, between the skins, even w/o a factory installed AC. The only draw back to my AC is that it is taller than the previous unit...but then my Yamaha 2800 powers it with amps left over.
