Air Pressure for blowing out lines for winter
I know it is on here somewhere but what is the pressure to use for blowing out tank/lines for winterizing. I have a 150 lbs compressor but I think I remember that I need to adjust it to 25-30 lbs max...

I crank the regulator on my 150 psi compressor down to 25-35 psi for this task. Blowing out one water line at a time, it is unusual for this to empty the (not very large) tank, and if the compressor has to start running, it has enough output to maintain flow at this pressure setting. For his job, what you need is air volume, not pressure, since you are blowing out open lines and not building up pressure.
