Hello, I have the problem ds I want to have more water at the shower, so a larger shower head mounted, and swups, more water but no more pressure, as far as clear, have a pressure water system. installed is a shurflo 7 the King with 7 liters the min and1,5 bar, so I thought a larger pump and the problem is fixed, said, a brought pump with, 19 liters the minute and max 5,1 bar. The water pressure is now absolutely great, as at home, however come t my water system to its limit in terms of pressure. now my question, why do I owe the good pressure, by the pressure increase itself or by the flow rate? Since I want to get a new pump, I would like to buy directly the right many thanks already. Josh
