An acquaintance of mine asked me to help him with this issue he is having with his new CO2 system and I couldn't figure out what is happening.
At first, he installed one of those cheap metallic bubble counters with an inbuilt check valve and every time the solenoid would shut off the system, the hose between the cylinder valves and the bubble counter would collapse, as if there was suction building a vacuum inside of it. The water from the bubble counter would drain completely, sucked back to the hose.
He then opened the check valve and fiddled with the sprint and apparently fixed it. He also installed one of those cheap plastic check valves before the bubble counter, as a precaution.
Now the water almost doesn't go back, but the lenght of hose between the two check valves is still collapsed when the system shuts off, and the hose before the first check valve is looking normal! I don't get how there can be vacuum after a check valve and normal pressure before it, it's like the valve is installed backwards, but it's not. I also don't know where all this suction is coming from. Can anyone help me understand?
Thanks
