Spray heads are designed to operate at 30 psi and rotors are designed to operate at 45 to 50 psi. When sprays and rotors operate at pressures higher than designed, both flow rates and inefficiencies increase dramatically. By using pressure-regulated sprinklers flow rates are reduced, misting is reduced and efficiencies increase by 10 to 30 percent.
