Remember that the water flow rate you get is determined by two factors, the
head pressure of your water supply and the conductance of your plumbing
loop. You can increase flow by increasing either. The former is increased
by a stronger pump. The latter is increased by increasing the diameter or
reducing the length of the water lines, which includes removing scale or
blockages from the lines.
