People have been using water trap dryer vents for decades with no
tells how to make one from a 5-gallon bucket, or you can buy them on
ebay for 8 bucks or so.
I took a look at the link you provided.
If I understand the instructions correctly, the vented air
goes across the water, rather than through the water.
Do I have that right?
If so, it would reduce the particulates, but certainly not
And that raises a question:
When you say "People have been using water trap dryer vents
for decades with no problems" what leads you to believe that
there have been no problems?
I'm not a "sky is falling" sort, but I do know that
breathing the sort of fine particulates produces by a dryer
is a serious matter.
You may certainly be correct in your assessment that the
bucket technique is a good one, but the fact that it is done
frequently does not tell us much about its actual safety.
I'd be interested in learning more about it if you might
have further information.
All the best,
It's cheap, it works, try it, if you don't like it you've wasted very
little. Set a clean smooth surface near the dryer, note what it looks
like after a day not running the dryer. Then run the dryer and wait a
day for the fines to settle and see what you get. If it's more than
your comfortable with, then worry about it.
We had a similar problem with our dryer vent which was vented to come
out the roof. We had a man come in and re-route it. ... the laundry
room is next to the garage. The dryer vent now runs into the garage,
then up to the attic and across ... coming out the fascia board.
Works great now. Don't know what caused the blockage in the original
way it was vented - but there is a clean-out in the garage if needed.

Did you inspect the outlet? Since your end is on the roof it may be
easier to clean it out from the inside. In your case I suggest buying
a 4" diameter dryer vent brush made for this purpose and use it every
Sometimes insects or animals will build nests in vents. Check for
wasps/bees before doing anything else. Install a 1/2" mesh hardware
cloth over the outlet if necessary.
There have been some interesting posts here.
The vent pipe in your wall should be rigid metal, so a wire brush
should not harm it.
If it is flexible of any material, replace it.
If you use a shop vac on "blow", then be sure to use it from the
inside of your home.
Be sure to clean the inside of the dryer vent termination cap on your
roof. Quite often, that is the source of the blockage.
Modern dryers are rated to push air through at least 25' of dryer
vent. Be sure to deduct 5' for each 90 degree elbow.
Good luck with this project.
