    I'm confused by what you mean about increasing the pressure. I'm currently a 3rd year mechanic engineering student, taking fluid mechanics right now, and from my understanding is that mass flow rate must be conserved (conservation of mass). So the flow rate out of the shower head is dependent on the construction of the pipes, elevation, and initial flow rate supplied to the home.
    The possible ways to increase flow rate is either decreasing the pressure difference by lowering the elevation of the shower head, installing a pump in series, or increasing the city's supply flow rate. Changing a shower head that increases the flow velocity ( by decreasing nozzle area) shouldnt increase the pressure.
    Idk, I'm still learning. I could be wrong or I could be misunderstanding "pressure" for fluid velocity. I mean, higher velocity= higher force, and taken over an area ( your body) is higher pressure in a mechanical sense.
