After finding out that old Boema machines have the Procon rotary pump mounted under the sink got me looking at the issues of plumbing in prosumer machines most of which use vibrating pumps.
From what I have read vibrating pumps are not really designed to operate with mains pressure inlets whereas with rotary pumps this is highly desirable. Also given that most prosumer machines are too small to fit a standard Procon pump would it not be desirable to fit the pump under the sink? Would this up the performance of these machines while improving their reliability?
