2017 International 30' HVAC condensate drain

[Jmacd]

Got some confusion regarding HVAC condensate drains on my TT. My 30' has 2 HVAC units. When I run the heat pump or A/C the condensate drains down the outside of my coach alongside the entry door. I've looked all over under the trailer and I only see a white and red drain line located in front of the driver side wheel well. They are connected to shut off valves which appear to drain the interior water system for winterization. My selling dealer was vague when asked and said the drains were exterior on the roof. Are there internal drain lines from the HVAC units? Am I missing the outlets? And do I have a plugged drain line? Thanks, Jim

Something is stopped up if condensate is running down the side of your trailer.

I was afraid of that. But I can't see where the drain lines exit the underside of the TT, that's my confusion!

They exit the trailer in the wheel well.

Left wheel well, front and rear of the well. Both are clear hoses. Check for insect nests blocking the hoses, and preventing them from draining, before a return to the dealer.

My 2016 FC 30'er has a 1/4" black hose in that area, presumedly for the drain.
No bugs or nests.

Back flush both tubes with a water hose and small nozzle. Not too much pressure, just enough to force water out the drain connection on each roof AC.

Make sure you rig is level. When connected to my TV in the front of our house, the ACs will drain towards the front; but when at a campground and level they drain to the wheel well.

Thanks everyone for the great feedback! I'll be heading out on the road again in two weeks for the great eclipse viewing in Oregon so I'll have the TT home for a few days before we leave to locate the drains and carefully clear them. I'll report back. Jim

If a water hose doesn't work, use the thickest weedeater you can find.
