I tried blowing my lines using a 2 gal Husky air compressor with no luck. I would hook up, turn on and by the time the line started bubbling the tank was empty and the compressor would shut down to refill. I ended up getting the job done by hauling over my dad's 26 gal compressor. For future closings I assume I would be better purchasing a tankless compressor that would run continuously so that I can just turn it on and let the lines blow out one by one???
