Use some soapy water in a squirt bottle. Pump up to top pressure.
Start spraying on all threaded conections into tank. Then work your
way down stream on any thing like the regulater connections, etc. You
should see small bubbles wherever you have a leak. Then dissasemble
and add teflon tape or even better plumbers pipe dope and try to fix
it like that.

Mine holds forever unless I leave a gun on the end of a connected
hose.

I have a new Campbell Hausfeld 60 gal. compressor that doesn't want to
maintain any pressure over a period of time. If I run the compressor
and bring it up to pressure, then turn off the motor, within 48 hours
the pressure is down below 20 psi. Obviously, there is a leak
somewhere in one of the connections, or in the tank itself.

I've talked to a contractor buddy that uses several small portable
compressors often, and he tells me that this is normal - not to worry
about it. To me, it seems wrong. I can see if the pressure dropped
down a bit over time, but to completely empty in 2 days?

So, what is a reasonable expectation for a 60 gal compressor holding
pressure?

The tank has a big sticker claiming that it includes on site warranty
service from the manufacturer, should I try to take them up on their
offer?
