I even have a lever shootout lined up with KarlSchneider (Mr. SO espresso), two grinders, a Gaggia Factory (La Pav), Gaggia Achille, Elektra and a Cremina. We will see how it matches up.

On the down stroke water is pulled out of the HX reservoir and pushed into the piston. There is no static pressure. If you lift the lever half way and let go, it just hangs there, lift it all the way and it just hangs there, no water. I am still trying to figure it out myself. No water is drawn, drips, leaks etc from the group until the lever is pulled down. During that stroke water is pulled from the HX water tank into the boiler HX.
The action reminds me of the old hand pump water wells.
I have a parts diagram that will be posted to the bench thread in time.
