Hello Everyone,

I have lived in my home now for about 3 years. It was built in the 80s and recently (and apparently shoddily renovated). 1000 square feet, one story slab. Not a bad little house really. But there are a couple of hack jobs I'm a not discovering...

I discovered that my clothes dryer exhaust exterior port is a fake. Yup, I had a bit if a reaction to that. Connects to.... nothing. Never did.

I found that the exhust is ran into the wall behind the appliance to a metal connecting duct, which is in turn connected to a plastic expanding dryer hose I found buried in my crappily blown in insulation.

double damn.

So I plan to suck out as much of the crap insulation as I can and roll in good fiberglass... but that is another discussion.

I would like opinions on the following. That hose has been in there for at least three years with good service... would it be within the bounds of good judgement to just attach a 90 degree to it and run a metal pipe straight over 12 feet (closest exterior wall) and put in a real exhaust vent?

I fear if I have to remove that hose from the wall I might discover a need to rip out some cabinets and drywall. I hate drywall and paint. And that area is pretty developed...

If I take this hack job and attach it to real work... is this a bad idea? Saves me some money and misery AND keeps the warm moist air out of my breezy as hell attic.

I personally would not consider a plastic hose inside the wall to be safe. The flex metal dryer duct is about as weak as I would go. Chances are pretty good you can fish it as it is only about 3.25" in diameter.

What to do with the hose would be secondary for me. More important would be to get it ducted outside before running it again, then you can decide what to do with the old. Any reason that you can't run straight through the wall? And I agree with Colby; definitely would not run plastic inside the wall, and try to avoid it altogether. Rigid duct, joints sealed with foil duct tape, not regular duct tape, and no screws so you have a clean shot out.

Welcome....

Nothing wrong with that 'crappy blown in insulation'.....I know it does not look good...but it works.

Nothing wrong with laying batts on top of it.

But you do want to fix that vent

Yes. There is no straight shot out. Its in the middle of the house.

I didn't run the hose, it was already there. Hence the issue.


It goes vertical for about 8 feet, then dumps into the attic. This is the issue.

And that is a big issue. You are dumping a ton of moisture up there.

How for to an adjacent wall?

On slab or do you have a crawl space?
