Other option is just to turn it off when you are not using it.

It might come to that. I's rather not, as my use is small and if it's
leaked down to 20 psi, it's a nuisance to wait for it to pump up, just to
use the blow gun for 10 seconds. Bob

Slight leakage at the tank drain valve is not uncommon. Small pinhole leaks
at the tank seams or even in the tank material might be possible.

The kid's bubble stuff in a spray bottle works great for finding leaks in
air equipment and in tires, wheels, etc.. It is handy for getting the
solution on the bottom surfaces.
