1988 Donzi Ragazza 25 fresh water pressure? for accessories

[Mike LEI]

I have gone over this boat top to bottom and cant figure out how the potable water tank gets pressurized so that the shower by the swim platform and the two faucets will work? there is no dash electrical switch that I can find and nothing in the owners manuels
does anyone have any info on this?

The switch most likely is in the cuddy on the electrical panel, would be in the 12v section
