When I let my Air compressor catch up to 120lbs and restart a tool the line pressure seems very low for a few minutes. What causes this? I am using 1/2" black pipe with a max run of 25 feet. I have 5 vertical connections with quick disconnects on them. This allows me to move my tools around the shop without a lot of hose. I've even tried a air nozzle on this set up and the output is still low for a while. It's not like a clog, more like it just takes a while for pressure to come up in the pipe! Weird I think. Any help appreciated. Chuck in NH
