Re: [APD] co2 won't stop
If the regulator main valve doesn't have an effect, then
it's not jsut a leaking solenoid.
Could it be the residual pressure (in the line after the
regulator, solenoid and metering valve) keeps the CO2
bubbling after you shut off the supply valves? If you have
check valves, the resistance to flow might be enough to
build up some residual pressure that then is slowly
relieved when the supply is cut off.
