Re balky cond. drain to Birddog Pilot:

Look back thru the thread, and find the one that talked about the mini-
condensate pumps. As I said, I printed that brand info to save... I'd give it
to you here, but I already put it in the RV, and walking on crutches is some-what of a production, so.....
Also, re plumbing traps in houses vis-a-vis virtually horizontal tubing on condensate lines in RV's, (usually 3/8's pex or something) The thread contributor comparing the two, is comparing apples to oranges. I know about this from years of experience in attics of houses with wet ceilings. I'm sure that the small pump offered by this company would fit in the space available, and would solve your problem nicely.

Thanks for the info "Dudley," I believe I remember the thread you are talking about and I think I might have printed out the suggestions about a pump; I'll have to check it out.
