Got my SAM a few days ago and found out it doesn’t hold air. Leaks from 3k PSI to a little less than 2k PSI overnight.Looking for some good suggestions on how/what to test. From what I’ve found so far, a balloon over the fill nipple is a start. And the pressure gauge is a likely spot to test too, but not sure how to test it.Thanks.
Same thing happened to me last month. I got my Benjimin Marauder SAM from AGD and only shot 100 pellets through it when I noticed it would not hold air over night. I sent it back and they replaced it. Now my new gun has a slower leak. It very disappointing. This is my first PCP and I love how this gun shoots but I am wondering if I should have saved my money and purchased something else instead.
Get some gas line leak detector solution from local hardware store, it will not promote rust, apply to suspect areas watch for bubbles. Both the gauge and the fill niple may seal if it is a thread leak, by just a little tightening with the gun degassed, firm hand tight snug should be enough, if the parts are not at fault.
Something else is just as much of a &^^& shoot. Most of these leaks are really minor matters and they can come up with any gun. At least with Crosman the customer service is right, and right here in the USA as well.
My bet is that the SAM has a leaking regulator. If you fill a regulated gun to 3000 and it leaks down to about 2000 and never goes lower it is the regulator. You can check this by pulling the action out of the stock, filling the pressure tube to 3000psi, find the small hole in the pressure tube just on trigger side of the gauge, add some bubbles and watch for leaks. If it is leaking from here sending it back is best as you would need to rebuild the regulator to fix it.
