Some photos of new Rocket Giotto Evoluzione - with plumb in. Just upgraded from PID-controlled Silvia.
There really is a noticeable difference in the cup (and channeling is history!)
On the filter cartridge head:
The left gauge is the inlet water pressure to the house - normally 60-85 psi.
The right gauge is the outlet pressure from the pressure regulator - set to 30 psi.
I've installed a shut-off for the water supply inlet to the filter cartridge so that I
can isolate the espresso machine from the water supply, for extended periods if necessary,
without having to shut off the cold water supply for the sink.
The white plastic shut-off valve coming out of the bottom pressure regulator outlet
has a quick-disconnect hose fitting. This permits easy installation of a short length
of plastic hose that empties into a bucket, to purge carbon fines after installing a
new filter cartridge (without having to disconnect the espresso machine's supply hose).
