I had my last Mobile Suites in single digits in SD for three days. The plastic manifold did crack but the Pex lines were just fine.

Point is blowing the lines with a bit of residue left won’t hurt a darn thing.

Only issue I have using air is the rusty water ,and what have you that can accumulate in a compressor tank, unless it's filtered . I see some nasty stuff coming out of a compressor tank when drained off , certainly wouldn't want that **** in my water lines .
