Hey my line going from the expansion tank into the WH has the pressure fitting /nut on the WH end and solder off the expansion tank "t" fitting. This is a flex line and it has a slow drip/leak. (perfect for waterboarding)
The nut came off just fine but the solder will NOT let go.
Question - The tank is vertical & above the intake line. Is there water 'trapped' in the line via vacuum?
I have released the pressure from the expansion tank & still no dice.
