A/C Condensate Drain Line

[Karen-Mike]

Just wondering what everyone does for an easy maintenance idea to keep the condensation line flowing well without climbing up and taking shroud off..etc..??
Thanks.

The drain lines are assessable from inside the trailer on the non-ducted units. Not sure how you get to them on the ducted units on 2015 and newer trailers.

Been on the road for two years full time. Only had issue with the rear ac not flowing once. Disconnected from the inside filter and blew it out to clear it. 2018 classic.

I've used this procedure on my home AC condensate line.

A wet/dry shop vac. Rig for wet and apply vacuum to end of the line. Suggest go easy at first (meaning apply some of the suction first) and if someone hears air at top I'd say all clear.

CAUTION I have not done this to my AS vent line, only PVC line on home that's why the go easy suggestion.

Thanks. That is what I did on my 2016. I will try it again on this one too. It had been fine most of this summer in Virginia. But now a slight flow along skin which drives me nuts. [emoji23]

Have you tried heavy weedeater line from the bottom up to the drip pan? Works for me.

YEP...up the tube.😂

I used to save it for my batteries....🤓

The weed whacker line is a good approach. If your 2016 (ducted) system is plumbed like my 2014 (unducted) system, the snake technique will clear any blockage in the main line and one side of the unit to the roof, but not the other side. So, the effectiveness of that technique depends on where the blockage is... if there even is blockage.

On my system there is a tee fitting in the ceiling that has a line from the street side condensate drain cup entering one port of the top of the tee, the main drain line headed to the wheel well across from it on the top of the tee and the feed line from the curbside drain cup enters at 90 degrees to those two lines. So... a weed whacker line will thread up the main drain line, through the tee fitting and into the street side drain cup. It will not clear the line from the curbside cup to the tee.

I run AC 6-8 months a year, even in storage. Condensate runs as a steady stream in the summer months here in coastal Florida, not drip by drip. Even when the drains are clear there is often condensate running across the roof here because the drain cups are in ambient air and the cold condensate inside them causes sweating on the outside of the cups to drip directly onto the roof of the trailer. Although undesirable, that’s normal in high heat/humidity given the design of the Penguin II.

To absolutely clean all drain lines I remove the cover inside the trailer (again, I’m unducted, your ducted unit would be different). The tee is clearly visible with three clear plastic lines. I pull the lines off the tee and flush them using an empty dish soap bottle with a mild cleaner (vinegar and water or bleach and water... you pick... vinegar doesn’t destroy clothes when it drips on you).

I have not had to do that often since discovering and fixing a kink in the main drain line that was caused when my trailer was built and the main drain line was 1” too short.

A bunch of us had a long exchange about AC issues that includes lots of pics and much howling a couple of years ago. Here’s a link: https://www.airforums.com/forums/f42...be-182389.html

I hope that helps!

We are camped in full sun. 90 degrees high humidity. Our single AC in the 25FB is keeping up well. Even shuts off on occasion. However, I noticed today, for the first time, the condensate was running off the roof, down the rear street side corner. I did not bring string trimmer line, or a ladder. It was bugging me, so I stuck a large bore straw up into the drain line. Taped around the outside and blew into it. I was nervous I’d flood out the drain pan under the AC unit, but blew it out anyway. Water poured out for a few minutes, and now it’s working fine. Dripping away. It’s probably a pretty temporary fix, but it’s working fine..

I inspect and clear any debris from the AC's a couple of times per year, on any RV we've owned and blow out the condensate lines with a rubber tip on a gun type nozzle from a compressor. Does not take much psi to accomplish, but does require pulling four screws at cover and a cute helper, (well at least mine was cute ). On our newer ducted unit, the drip end of hose exits in front of fender well above front tire on curb side. I had to clear factory debris from line and had to disassemble the "T" in the cold air return in our 2021 GT, as condensate dripped into the interior ceiling on initial AC use.

Stick the funnel in the condensate discharge and then blow on the attached tube.
Works for me most of the time.
