this means I have a high pressure system.  There are 2 pieces of
terminology commonly used with showers - pressure, and flow
rate. As I understand it, the flow rate determines how much
water can pass out of the shower per minute, and pressure
determines how much you can restrict the water's egress while
maintaining the flow rate.  Now, I want to get the most powerful

because I have a high pressure system. In my experience, though,
what makes a shower feel "powerful" is a third factor - the
water velocity. The velocity of the water coming out of the
shower head makes a major difference - if it's really fast,
that's what I call powerful, as it can give a really nice
