Question

Need advice--challenging dryer vent duct installation


Facing a challenging dryer vent duct installation--see pictures. Yes, that's white vinyl flex duct the builder installed in the ceiling 20 years ago--what was he thinking?! I see why he wanted to, with all those pipes to dodge, but they must be replaced with rigid metal, and I want to maintain the in-ceiling installation if possible.

- Advice on getting around the pipes?
- Are there code-acceptable transition pieces available for getting through tight spaces like that where 4" round duct may not fit?

Thanks,

Cameron

If you run metal it can condensate if not wrap up with insulation. That is if cold air is getting around that pipe and dryer is running then outside temp is below freezing.

I do plan to insulate the duct where it runs through the attic (not shown)--what's in the photos has finished space above and below. Will probably also have to add a booster fan because of the length of run.

Most dryer mfgr's say no more then 25 feet of 4 inch duct metal duct and no vinyl ducts. 90 degree bends add 5 feet to the length of your ducts. Your run looks long to me given the bends etc. So, I think you will need an approved dryer vent booster. They are pretty pricey!!! Some come with automatic start sensors. Also remember they cant be walled into ceiling etc.. You have to allow for service.

Most mfgrs also suggest cleaning or inspecting the duct work for every 6 to 12 months. From what I have seen in your pictures, there is just about no way to do that!!! I would be looking for a different duct path. I am sure that you already have!!!!

Good luck and you might think about a clothes line!!! LOL (yes that was a joke!!!)

I'm afraid the laundry is an interior room, and we're on a slab, with finished space directly above. No other paths available, unless I run a chase through an interior room, which wouldn't allow for inspection, either.

Thanks...I was afraid of that. Fortunately, there's sufficient duct run in the attic near the vent exit that I can fit one in, I think.

My wife was serious when she suggested it...would probably be faster than our dryer in its current state! Thanks for the advice!
