The neoprene hose is pretty stuck on. If I get it off, low pressure or vacuum are my choices. Thoughts?

White hose in motor section and in gennie section are really hard to get at. Need small child. Thoughts?

If you have a little slack, cut the end off?

I think if I could get it off, pull it down and try a quick "mouth to hose" blow. Maybe a mattress inflater ... probably one in campground somewhere.

Thanks for all of the good advice. Will work on it sometime this month

Went to the HW store for 4 ft of clear 5/8 ID hose. Put is over the end of the drain hoses and blew them out with my own lungs! Never felt resistance, but they work now! Woot!

Cool! I was going to suggest you get a piece of line from a string trimmer. You can poke it up the coil side without worrying about making a hole, it is also flexible enough to go around a corner and if you want to roto root the drain just run it off the spool. It's what I used on mine.

I would suggest , in the summer a small amount of bleach poured in the line will prevent stop ups .I worked maintenance for 30 years and in houses we did that all the time.Its called cold water slime.

The clog was in the plenum up topside. Dust. Just a puff of my breath from the bottom of the hose took care of it. No good way to get bleach up there.

If there is a will there is a way. You know if you weren't suppose to get bleach in there you somehow would. Lol

If you look at the install up on the roof you will see that the other end of the small hose or braided hose on most models attaches to a collection cup between the roof and the base of the a/c. With the a/c cover off you can drill a 3/8 hole in the top of the housing directly in line with that cup. Flush with water or blow gently with air to clean, then put an ounce of bleach in the cup. If you do just the bleach every spring after you initial cleaning you will not have clogs again...do it when humidity is high so it actually drains and works it's way through the system...just like maintaining a S&B drain. Cover your drill hole with a little Gorilla Tape or find a small plug. Gives you a chance to clean out any wasps, leaves etc. Small amount of oil on the fan shaft. Stainless washers under the a/c shroud screws so the shroud doesn't crack out. Check electrical connections, clean coil if necessary.

DO NOT USE HIGH PRESSURE AIR on the hoses... most Monaco's have a joints, T's, els, whatever buried in the ceilings, if you blow one of those apart you have created major work for yourself.

A really good tech will probably do all three units for about $200-$300 the first time, easy after that, maybe 1.5 hours a year. Assuming you do not have a line that is pinched, disconnected, or whatever from the factory....yeah it happens.

Interesting!
I cleared the dust clog as noted in previous post

Dust becomes mud this time of year in FL...puddles of drainage under the coach from all three a/c's right now.

I guess that's why 75 northbound is bumper too bumper. Count me in that pack in two weeks.
