give it a simple leak check.

1. put the system on co2 tank, charge it with co2.
2. set the output pressure to 50 psi, then solenoid off, co2 tank valve close.
3. leave it for 6 hours, if nothing change, means no leak from the CGA320 connection to the solenoid(not cover the parts or the tubing after the solenoid).
4. the parts/tubing connections after the solenoid, use soapy water to check leak.

if no leak, one or two psi rise after solenoid power off, may be the problem of a lazy stainless steel diaphragm, should be ok if you set the output pressure high enough, about 40-50psi.

So, could you test both chambers at the same time? I read your initial post awhile back and according to your guide, the two initial steps are to test the first and second chamber for leaks.
