The facility I work for has a dryer vent to the roof. Even when it hasn't rained or snowed, hose down builds up in the exaust hose. I hold disconnected the hose several times(approx. every two weeks) and emptied 2 quarts of hose down each time. This significatlly decrease drying time, but when we finally got someone to come check it, they shortened the hose, and clamped it on so it can't be removed in need tools. Dryer was taking forever again so I feel the hose and I can feel nearby is alot of water, but in a minute I can't remove it to empty it. Is in attendance anything that can be done to decrease the dampen that condenses in at hand? Remodeling is not an option, so it have to stay vented to the roof. Also, concept that don't require a lot of money are greatly appreciated, I work for a non-profit cleaning. Even better if it is a fix that I can do myself!
Answers: First make sure the vent have the proper cap on it to prevent rainfall water from getting down the vent. The other place where on earth water will catch in is condensation inside the vent from the dryer exhaust (remember it is reheat moist air from drying the clothes). You can lend a hand limit the condensation if you can insulate the vent stack. They build fiberglass wrap insulation that should be fairly undemanding to install. A final solution you can try is to make a small hole within the bottom of the pipe (or flexible hose) where any condensation can drain out. You may want to put a pan or bucket beneath it and check it as needed to empty it past it overflows.
The vapor in the vent air is condensing and running down the pipe. My guess is the constituent of the pipe that runs through uncondtioned air space is the culprit (attic?). Try insulating that cog of the pipe and see what happens. Venting through the roof is not unusual. Also, flexible pipe (the stuff that stretches and bends) causes nouns flow turbulence and slows down the air moving through it. If you enjoy straight runs, replace it with rigid pipe--you can find this stuff where on earth they selll venting supplies at HD or Lowes.
