Hatsan Slow leak pile driver

@redsqnm I don’t have a Piledriver and I’m not familiar with the platform. I’d think to look around the gauges and the where the reservoir connects to the valve body housing (as with other airguns). @gendoc is the main member that I’m aware of who shoots a Piledriver, perhaps he can provide more useful input here.
 
how do you check for a slow leak I have used soapy water on stuff other than air rifles you could see it making bubbles where it was leaking
yes that can be done, or submerge filled gun in water and watch for bubbles.....
and cleaning the gun completely soon after.
also, but a balloon on the muzzle to check valve, poppet and so on.
