If the water is coming out of the group head, then that is as designed. If you look at the instructions for the machine, lifting the lever lets the water out (if the basket is full of espresso, this is how you begin the process to pre infuse it)
I'm assuming that since this is the second re seal that the water is coming out of somewhere else?
Yes, this is quite normal, when you lift the lever of a La Pavoni Pro all the way to the top, you start filling the group. I will usually count to 10 or 12 when pulling a double and look for the first beads of coffee to start making it through the filter though my bottomless portafilter before pulling the lever down to extract the espresso. This 10 - 12 seconds is what I consider the pre-infusion phase and I'll use closer to only 5 - 6 seconds for a single basket.
The water gushes out because the La Pavoni has a pressurized closed boiler to be able to steam milk and heat the brew water. The lever handle is only to apply pressure to the water in the group during the pull and doesn't actually pull any water from the boiler when pressing down, the cylinder is below the fill hole when you lower the lever.
