A/C drains

Yahoo Message Number: 89691
Hi All,

Does anyone have any knowledge of coaches like mine having A/C drains. If mine does, then they must have always been plugged since the condensate runs off the roof and down the side.

Thanks,

Don Krahling

On our bus the A/C units have a condensate sump and small shaded pole motor driven pump. The condensate sump collects the condensation off the evaporator and the pump pumps it out through a plastic hose. One exits out the rear and the other exits out the front. I'd to a visual inspection of all this and flush the hoses out delicately with a 10:1 chlorine mixture. Might be a good idea to start with fresh water first in the event the drain tubing is busted somewhere along its route. Not point in pumping chlorine down your walls. That's the scene on our bus.
Be advised different A/C unit might handle condensate removing in different ways.

We have three AC top units on our coach. They all have drains. The back one never seems to clog. The front one I had cleared a couple years ago and it drains through it's tube where it is supposed to. The middle one we have had cleaned a couple of times and it sorta works sometimes. Mostly the mid one drains down the tube and also down the side. I do not think my drains have pumps on them.

A timely subject, for me.

My rear AC drain seems to be plugged- i.e. condensation drips from the unit onto the bed.
I have searched for the upper end of the drain tube with no luck- I took the rooftop cover off, removed all the metal covers to no avail. The same was true when I removed the cover inside the coach, although I could see some pex lines that tee together. I'm pretty sure they are part of the condensate drain, but could not find the open end.
I tried running a wire up from the bottom end of the drain tube- it went about four feet before reaching a hard obstruction, which I believe to be an ell or tee fitting, rather than a clog. I tried inputting compressed air at the discharge end, hoping that, if nothing else, I would be able to locate the upper end by the sound of air escaping at the unit itself. Nothing. I am reluctant to put a lot air pressure into it for fear of causing some damage. If I could just find the input to that drain tube, I think I could fix it.

Any suggestions, anyone?

Our 99 Magna and our 2006 Affinity both have drains to take the water out of the A/C's to the ground. Our 96 Intrigue did not and water ran off the roof. I would tilt the coach just slightly to the driver side so it didnt run off by the door.
We have found the higher the humidity the more water you have. In our 99 Magna, when we turned the air off we got a down pour inside the coach. i think we probably needed to adjust the tighness of the "J" bolts holding the unit on the roof.
I use a wet/dry vacuum to suck the water/gunk from the line occasionally to keep it cleaner. I do the same thing with my home air conditioner since we live in such a high humidity area.

Good luck.

My 98 Intrigue drains water to the roof. I had gone up and hunted for drain lines and found nothing

On my 06 Intrigue the air conditioners have a condensate pump that pumps the water into the drains. You take off the cover on top and as you are looking toward back of coach you see a hose about the size of wiper washer fluid hose. If that hose comes off then the pump just pumps water out and it will run down the coach. If the condensate pump quits working then the water will run down and drip (or run as was our case)onto the floor or bed. I found when I used compressed air to blow up from the bottom that it blew that little hose off. Once I replaced the hose on the pump then shortly I saw water dripping out of the drain hoses under the coach. I have one pump that isn't working and I need to get it fixed. That 3rd air conditioner sure is nice in some cases.

I meant to say as you look toward the rear of the coach you will see a small silver box which is the pump on the right rear. The small hose will connect to it.
