I know we’ve discussed this before but I think this is a new twist. My brother is a plumbing and heating contractor who specializes in radiant heating. He did a big office building recently with multiple boilers and vented them with flexible aluminum. He has a bunch of 4″ left over and offered it to me for my DC ducting. He said it is strong stuff and doesnt think it will colapse. Obviously I will test that first but I was wondering if anyone else has used it, what the results were and if there is any need to ground it. The big advantage is that it is cheap compared to ABS.
Thanks in advance

If it's aluminum, it's pretty easy to ground. Just attaching it to the frames of the DC and the tools will end up grounding it.

Use it by all means but be aware that the static pressure loss of any flexible is about 3x that of rigid, best to use them in combination, unless you are running the DC & the machines in close proximity.
Lets face it, its not expensive if it's left over from a job.
