Water flows by gravity down a roof tank and pumps to 4th storey below roof, is a pressure reducing valve needed if height of floor 3.5m?

There is insufficient information to determine the answer. What kind of pump? What are the pressure limits on the system? Does the pump run continuously or is the operation intermittent?

p = ρ g h
p = 1000*9.8*(4*3.5) = 137200 Pa = 1.354 atm
no need of pressure reducing valve
