alright...this is getting extremely frustrating.
I retaped everything, made sure all connections are tight. Sprayed soapy water over everything and didn't notice any bubbling anywhere.
I turned on the tank and set my pressure, turned on the solenoid and set the bubble count to about (2) BPS.
I went to the gym, come home and check things...the LP guage is 0 again!!! WTH!!!
I'm really open to more advice here guys and gals. Driving me absolutely nuts!
My reg should be back this week so it looks like the temp one won't even be useful.
