AC mystery
 
I turned on the AC of my 73 Soverign and water came gushing down into the trailer. The unit didn't have time to build-up condensation. Could it be rain water? Why did it leak when turned on ?

Are you still using the original AC, or has it been replaced? If replaced, what brand/model, and how is it connected to the condensate capturing system (ie., is it sitting in a plastic pan, or does it have the cups-and-hose set-up?

Yes it is the original AC unit and housing.

You probably need to blow out the drain tube. It will probable be hanging down in one of the wheel wells. If it is plugged your AC won't drain either condensate or rain water.

Thank you, I don't have a compressor at campsite, could I pour bleach down line or try to replace?

It would be difficult to replace since it runs between the inner and outer skins. It will probably take some amount of pressure to clear it. You might try canned air if you can find any.

I had a 73 Sov. Someone had put a piece of screen in the drain tube that had clogged. It allowed a small drip just so you thought it worked. Still backed up into pan. Pulled screen out and worked great.

That's exactly what seems to be happening. I will check for a blockage this weekend. I will get a way to blow some air through it. Thank you

I would not put any more pressure on that line than necessary to clear the obstruction or you might blow a hole in the line or blow a fitting. You can remove the interior shroud and you can see the line and the plastic fittings to check for obstructions and condition.

More than likely, the obstruction will be at the tee fitting just under the unit.

FWIW, on my 72, the only trouble I have had with the drain is when the plastic tube that traverses the wall split where it plugs into the tee fitting.

I simply cut an inch or two off and slipped it back on the fitting.

You might use a detergent in the line, but if I were you I would avoid bleach.

Maybe you could borrow a bicycle pump and tape to drain hose in wheel well to do a quick fix?
