I think you started to use the word "fact" which is what I challenged.
I also never said it "couldn't permeate"...I just said mines fine after 3 years of liveaboard
use and a constantly semi filled holding tank
...I said I can't imagine what is 'building up" in a vent hose unless it splashes in the very bottom of it or the tank is being overfilled.
Working in the marine
industry 15 years now and the 3 years at a Sea Ray
dealership with their "fair share" of inexperienced boaters up scaling to boats with "systems", I had my share of cleaning
out the vents and vent filters.
If you let the tank overflow into the vent....yep....cleanout/replace time..
If you don't, I'd love to know what's "building up"....I haven't ever seen it.
I use the cheapo stuff because it's cheap, easy to work with, and PVC so it's "permeation" is relatively low even compared to the hose that's way more expensive hose. If it does start to smell...it doesn't hurt so much to replace either physically or financially.
I'm just saying for vent's in general or for water
fills...I can't imagine why one would spend money
on "best quality" when the outcome is pretty much the same.
