power tube problems in A5

I thought tippmann was supposed to mean quality.  I got an a-5 a couple of months back and I was thrilled.  I used it a couple of times, making sure to follow the instructions in the manual.  Then, the very first time I field stripped it, it went fine until I tried to put it back together.  I had followed all the directions perfectly and when I tried to put the gas line back into the upper receiver, It wouldn't go. I kept on trying, then a washer fell out of the power tube.  That scared me.  I sent it away to tippmann and waited.  I got my gun back two days before my next big game, supposedly good as new.  It shot fine that next game and I was happy again.  Then I tried to pressurize the A5 this morning and all the CO2 leaked out of the barrel immediately.  What the heck's wrong with my marker?

The problem may be all about me(meme) Have you read any of the stickies about troubling shooting and maintenance? Have you looked at the exploded views? Get over your panic and your need to blame someone and read up on the piece of equipment you know so little about. The ruggedness and dependability is no small part of the reason why Tippmanns dominate the rental market. Look at the parts of the marker; from paint job and gas connections to how the power valve works and the hammer recocks after each shot. The A-5 is simple, straight forward and easy to understand if you take the time.

BTW, welcome to the forums and realize that this a resource with literally thousands of helpful posts that are easy to search, not just a current events discussion group.

Forgot to mention to try cocking it before pressurizing it and let us know what happens.
