AC Condensation (or water) leaking into coach

[Dricha 7]

I have a new 09 Phaeton 36QSH that sometimes will leak noticable amounts of water via the air vents (not the intakes) front to back on the psgr side of the coach. I brought it to the dealer who was unable to replicate the problem. I was wondering if anyone else is having a similar issue. Not sure if maybe its not rainwater somehow getting into AC unit on roof and finding it's way into the system and then getting blown into the coach when i run the units.

Also, excessive wind noise and windows not shutting well is a problem and I have been waiting for many weeks to hear back from the dealer (Dixie RV) on this and a few other issues.

I sure hope I am able to soon experience this great service I've been reading about.

Not sure if the same problem, but our 07 Allegro Bay did the same thing when new - leaked significant water from AC vents (not intake) and when we were caught in a significant Florida downpour, the water really came in. After 3 tries, dealer finally fixed and repair was listed as a "Tiffin recall wi000104".I never asked and was never told what the recall was about, but the problem never reappeared.Sorry I have no other details of the fix.

Dricha,
Welcome to IRV2 and the Tiffin group. I hope this gives you a direction to look. You may want to call Tiffin directly, they are very helpfull.If you would like I can add the Tiffin Karma to your signature, just ask!

Dricha,
Supply-air side is dehumidified air & cannot produce moisture. Return-air, however, can drip under very humid conditions.

With your set of circumstances and unsure of rain as the culprit:
It appears you first need to rule out either rain infiltration or condensation as the source. Remove the rooftop shroud and look for any backup or blockage of the condensate removal system. This is the easier (and non water-damaging choice). Any water discoloration trails might be evident.
I believe that your condensate lines are piped from the drain pan at the unit, thru plastic tubing , routed into a void in the interior wall,and exiting underneath the coach. Do a search of the tiffinrvnetwork forum for "blocked a/c drains". One post noted a problem at the "T"� fitting and another with a pinched-closed spot along the pipe within the a/c unit. Check the line carefully.

If rainwater were to be the source, a simple hose-off-the roof test would reveal that. You wouldn't need to force water under the unit; but rather, just a sheet flow of water across the roof surface. Removal & Replacement of the self-sealing gasket kit would be done for this.

Hope this is of some use if your' a DIY'er

We had this same problem a couple of times. Once the water was dripping from an a/c intake vent and the other time at a seam in the soft touch ceiling. Both times it was because the coach was not level and the normal drain was on the high side so the condensation sought another route.

My drain line was plugged ( actually it was crimped so water could not flow past the crimp)on the front AC unit causing water to leak into the vents and ceiling pad. have you checked the drain lines from the Ac pans yet?

Do you know where the air conditioner drains come out in your rig? In our Bus the front AC drains under the front cap on the driver side. The rear is under the rear cap on the passenger side. Run your units and be sure you're getting some water out of BOTH of these after about 15 minutes. That will tell you the lines are clear.

Problem found - Tiffin and dealer (Dixie RV - Hammond, LA) found clogged filter and seconday impeller pump was dirty. They adequately explained the design and function and cleaned the path and tested it out. I wont know for sure until the Spring if this did the trick, but I am pretty confident the problem has been addressed.

Thanks to all who posted ideas! This site is helpful!
