Just for kicks, when it warms up, try the pigtail you removed. It is possible that the pigtail is fine, but by removing and replacing with the tank shut off, you reset the tank protection mechanism. I have had to disconnect, wait and reconnect my tank connection if I trip the protection mechanism by opening the valve too fast into an uncharged line.
