I think one of the Acme nuts may be broken. When it's tight there is still play in the line...so no way it could be closing the tank valve. QUESTION - if I steal the line from the other tank, leaving nothing attaching to that tank (it's Sunday and nothing's open), will the system still run?
Yes that pigtail is bad....when connected there should be no movement.
You can use other pigtail but why?
Valve out both cylinders
Swap lever to other cylinder and slowly open valve
Which ever cylinder is opened first is primary...lever switches indication for RED/GREEN dial.
IF neither cylinder flows you could have 2 bad pigtails
(Without a hose connected to cylinder service valve--OPD----no propane will flow out if valve is opened. The spring loaded shut-off inside the connection has to be pushed open bu the 'center stub in ACME Nut)
