Storage pcp rifle tank

[TouYang]

How long can a pcp be stored with air in the tank ? And is it normal to slowly loose air over time , say 1-2 weeks and more ? 
or is this a sign of a leaking pcp rifle ? 
I have the hatsan bullpup QE .25 in synthetic stock and I’ve notice one loosing air throughout the week and the other maybe a little after 2 weeks.

it’s not a big issue at the moment but would hate to keep needing to check on this weekly 

Thanks for any input

Should hold air for months if not years.

Weeks? Sounds like a leak to me.

Sounds like a leak to me too. I haven't shot my airguns in months either, but they shouldn't slowly lose air that quickly. My AG's only dropped by a hair due to cold weather. Hatsan also know to have QC issues. might want to investigate more.

Slow leak! Should hold pressure for a LONG time w/o leaking.

Many of mine have set for months with little to no issue. Some lose a bit, some don't. None have lost a lot other than a Condor with a defective Altaros gauge.

Thank you all for responding to this , I’m fairly new to the pcp world , I’ve have a few springers , and thought pcp is the way to go , but so far my experience haven’t exactly been smooth sailing.

with that being said , I think I’ll hold off on investing any more into pcp, if it wasn’t for the fact that ammo and paper works for regular firearms is the deal breaker , I don’t think I would have invested so much into pcp.

although now I’m all set , I have a few pcp, air compressor , pellets , (haven’t try slugs yet ) I do enjoy plinking A LOT , it’s very affordable with the .177 pellets . 


again thanks for all the inputs .

Hi...My Marauder pistol will hold 2500 psi for a year and a half and then, suddenly, begin to leak down slowly. I have replaced the seals on two separate occasions and each time, it is good to go for another eighteen to twenty four months.

Another PCP I own will leak down its contents in a week. Go figure.

Thanks guys, all these information is good to know, wow I didn’t know that unlike regular firearms , this could be a constant investments (replacing the seals )
