I recently bought a used Victor 250C off of an auction site. They said it had been tested and was working normally. I was hoping that was the case but I wanted to put it through Bettatails leak test just to be sure. The high side tested out fine. It held 800 PSI overnight. When I isolated pressure in the low side, the psi slowly dropped. I checked for and fixed a couple leaks in the post body. When I tested again, the PSI still went down more than it should. I soap tested again but couldn't find any more leaks. So it appears there is an internal leak. I put a plug in the output and charged up the low pressure side again. It dropped some, but not as much as before and it seemed to almost stop when it got to a certain point. Today I tried again with the output plug, but I left the high pressure side charged as well. The PSI is now slowly rising a couple PSI an hour. So I'm not sure what's going on. Can anyone make sense of this? Is it even usable? Or should I just cut my losses and hope for better luck on the next one?
So I left it for 6 hours last night with both stages charged, and the PSI on the low side increased from 62 to 68. So I released the CO2 from the high side again and left it overnight. This morning after sitting for 8 hours the low side pressure dropped from 68 down to 49 PSI. It seems like the leak is between the two stages. Is this really a problem though? How would this type of leak affect the system when in full use? Does anybody have any advice?
