Problems filling accumulator
I purchased a used 15l a couple months ago, the first two runs went great, but it was obvious the pump needed to be rebuilt. After rebuilding our pump and now on our third run we can not get the accumulator to get to pressure, every time we check for “snow” it’s still only air. We’ve put plenty of CO2 into the system and are still at a loss, no major leaks in the lines from the pump to the accumulator. Any suggestions would be greatly appreciated.
