For blowing out lines, volume not pressure is the primary consideration.
As long as the 6PSI can overcome the head enough to get the water starting to move out of the fixtures, it should work fine.
Thanks... that's what I thought too.
I tried it this morning and at first I got a really good slug of water out of each of the faucets. Then I got blowing and mist -- Good signs.
But then I got to where the pipes just sort of gurgled -- Not a lot, but enough to know that there was still some moisture in there.
Going to try to modify my connections and I did forget to isolate my water heater. See if I make out any better this afternoon and can avoid buying a compressor.
Sounds like you aren't getting enough pressure to overcome the head and then air bubbles just slowly gurgle thru.
If it's not getting a clear flow of air, there is likely too much water left and you will have to try other methods.
One thought: can you apply the air at the fixture so you are pushing the water down hill to get most out and then go back and do a good blow to get any residual?
Houses are not really a good comparison as it's typical for them to have plumbing going from the basement to the first or second floor with 10-20' of head to overcome. In an RV, it would be rare to have more than 5' of head to overcome.
Also most people use compressors because... they have a compressor.
Regardless, don't leave it just gurgling as that means there is water still in the lines.
