I am building a new home. Could you tell me which manufactor has the highest flow rate showerheads? How can you “test” a showerhead before purchase? Which factor is more important for a great high pressure shower: flow rate of head or psi of line input? Thanks Dale
All showerheads are restricted to the same maximum flow. The only thing that is not regulated is how many shower heads you can put in the stall. If the head has a removable restrictor, then you can increase the flow by removing it. Flow volume is determined by both pressure and flow capacity. With a given shower head, and without a compensating flow regulator, if the pressure is increased flow will increase, and if the opening size in increased, flow will also increase, but pressure will decrease.
