I have five flower shaped over head shower for raindance mounted at the height 5metre and there are 7 such flowers with each flowers contains 25 nozzles. The pump is connnected at ground level to the tank.

What would be the pump capacity and dia of the pipe requires.

SA.

There should be stamp somewhere on the shower head stating water flow. But in any case, if I am not mistaken, these "star" shower heads are 2.5 g/m flow shower heads. They should operate under 15 lbs of pressure, no problem.
