Ok, I hooked my system up, turned on the switch, pump kicks right on and on up to 105 it goes and shuts promptly off, works perfectly... maybe.... how much bleed off of air is normal? I listened REALLY carefully at the tank and pump and fittings and can't hear any leak, I listened at the ONE and only splice I have for the air pressure gauge line which I used a brass coupler fitting and then put silicone on the threads and outside of the nuts. I can't hear any leak. it goes down to about 90 lbs. from 105 in around 30-40 minutes. Is this normal for the press the hose into the fitting type lines, or do I need to get a Dr. stethoscope thingy and listen better?

Ok I don't know much about on board air systems, but I do deal with leaks a lot at work. Listening for a leak won't cut it if it's small, you gotta get yourself a squirt bottle and fill it with a soap and water mixture.. any ratio as long as the solution will get soapy. Spray this all over the fittings, anywhere the hose could possibly leak, etc. Just watch for bubbles forming or growing, then you'll know where the leak is.

edit: when you find where the leak is, take apart the fittings and clean them real well, then apply some sort of pipe doping on the threads and reconnect.. Don't be shy with the doping.

Also if there are no leaks in the lines, the air could be backing up into the compressor from the tank. I dont know what kind of compressor you have, but they do make check valves for compressors to avoid this problem. I have to big 10 hp gas compressors and this kind of thing happens.

teflon tape helps too

Thanks, I was planning on the soap thing today.
I was just thinking maybe it was normal for press in line fittings.
I have a one way check valve immediately after the compressor,
and plenty of teflon tape on everything.
I guess I assumed the well DUH stuff would not need to be mentioned as having been done.

Is your storage tank getting warm? You will see a slight decrease in pressure as the storage tank cools. But I think 15 PSI would be to large for that depending on size of the tank.

Thanks to all for your suggestions, had 3 TINY TINY leaks from a few fittings, had to tighten and such and seems to be holding for now. Thanks again.
