Blowing out water lines in Class A
Apologies if this was answered in previous posts. I suspect there is a very simple answer. This forum and YouTube have been very helpful yet I have one open question: I plan to winterize my RV us...

So now I know why I’m confused, the manual for mine makes no such admonition (page 8 in the attached link) against using compressed air to winterize.
I guess we’ve been lucky that in 10 years and winterizing multiple times each year we’ve never had any issues, nor our friends who also use air on theirs.
AquaHot Manual clicky
Depends upon the model of Aqua Hot on whether they place that warning in the Owner's Manual or not it appears.
From my Aqua Hot Manual, "WARNING! YOU CANNOT BLOW DOMESTIC WATER
COIL OUT WITH AIR TO WINTERIZE AQUA-HOT."
Doesn't make sense if using compressed air "correctly" but, I blow mine out, then follow with approved anti-freeze as per manufacture's recommendation. I've heard horror stories about owner's failing to winterize their Aqua Hot sufficiently and the result being obscenely expensive. I've always blown everything out over my RVing history of many decades but, I'm not rolling the dice with our current Aqua Hot system. Simple and inexpensive to follow the recommendation.
Back to the OP question, I suggest following your manufacture's recommendations. If they suggest using compressed air, as others have already mentioned, your tire inflator likely will not produce enough volume.
