Thank you guys. Please let me know if you have any other thoughts, otherwise I'm taking it next Wednesday back to the shop and have them rip right back into it. I'll try to let you know what happens.
It's a new valve and should be under warranty if the valve is the problem. I wouldn't be tearing into a $400 part hoping that it is the problem unless it is a old one.Check the circuit from the tank selector switch back to the valve connector & tear down the tank selector valve itself. The return plunger has to be hanging up, lube the orings with silicon grease, should solve the problem.
