Armstrong 10 A/C mysterious leak??

Two nights ago, we had a heavy downpour with winds blowing into the front of our '75 Argosy 24'. We were in the process of installing new flooring when we heard a drip drip on the plywood . . . looking up, the water was coming from the A/C with a fairly steady drip!

We removed the interior cover to find accumulated water dripping from the area indicated in this photo

Last night, we had rain again, heavy but not blowing. As a precaution, we taped a heavy around & under this opening - the bag was dry this morning.

This is the first time that we've experienced such a leak in the 8 months that we've owned the trailer. We spent two months traveling around in it this winter & did experience a few downpours. The area around the A/C between the inner & outer shell appears dry & the insulation is dry as well.

Any suggestions/comments as to how the water is entering this "hole"??

What do we need to look for in order to remedy??

As always, any voices of experience from this great forum are appreciated!

Sounds like the drain line is plugged up.

The sound of air

Thanks Andy! Looks like you were spot on!

Searched the threads for methods to unplug the a/c drain tube and hauled out the air compressor last night. Gerry positioned the compressor at the outside exit tube while I stood inside with my fingers around the other end of the tube, which is attached to a metal pipe that we presumed is the lower end of the drain pan. Interestingly, this hose is held in place by a friction fit, no clamps.

I listened & tried to "feel" if any air came from the hose. I didn't hear any air or "feel" anything on the first blast with the compressed air . . . hmmm . . . then a second blast & viola! I could hear the air rushing through the tube.

We sent a third blast thru the tube, just to verify that I wasn't hearing things & same result, the sound of air!

The interior tube connection must still have a good seal as I didn't "feel" any air leaks.

So, we must conclude that there was something stuck in this drain tube, which was causing the leak. We won't be able to test this theory as there's a welcome dry spell forecast for the great northwet! Will have to add "blowing in the tube" to our annual maintenance list!
