Broken or clogged A/C drain line

[danjoe91]

I just ran the Coleman A/C unit for the first time since buying my 1985 Excella. I noticed water seeping out of the seams at the decal-belt line the entire center section of the trailer. I can only assume that the condensation line is either clogged or broken inside the walls. Has anyone else dealt with this, and what can be done? I am afraid to lean over the top of the trailer to the air conditioner for fear of denting the roof in. Help! Joe

Joe, pics help. Info on specific ac unit, year of AS and ac, is there a tube under the trailer for ac drain?

The Coleman Mach was installed in 2000 by Metro RV in Burbank, CA. I did find what seems to be a drain hose near the left side of the trailer in front of the wheel well. No moisture was coming out of this at all. The water seeping out, however, was coming out of the right side, and there are water stains in the bedroom ceder closet. It was seeping out of a good 8' of the side of the trailer right above the decal-stripe. The trailer does not leak at all in even the hardest of rains. This all started when I ran the air for the first time.

Set your compressor to about 10 psi and blow back up the drain line in the wheel well. Works most of the time.

Yup.. don't use too nuch pressure.

It sounds like this is second ac. No way to be sure but sounds like the hose pulled out where it was initially run.

Checkninside closet.

Today I ran my electrical wire puller up the drain hose from near the wheel well, and it came out inside the A/C unit in the space between the ceiling and the roof. This is not right. I looked through the installation manual and not one word is given to installing or hooking up a condensation line at all. This is a Coleman Mach- 8000 series installed in 2000. The hole for the line in the pan of the unit looks as if someone drilled it out themselves just to stick the existing line somewhere. Would this unit need a line? The condensation is now leaking into the walls of the trailer.
