Estimated Water Savings Using Rain Bird 5000/5000 Plus PRS Series Rotors

5000 PRS Water Savings

Rain Bird's 5000 PRS and 5000 Plus PRS in-stem pressure regulator ensures maximum nozzle performance, even with varying inlet pressures. By maintaining a constant optimum pressure of 45 psi at the nozzle, 5000/5000Plus PRS rotors end misting and fogging caused by high pressures. For you, that means water savings.

Calculate your estimated water savings:


Enter the pressure (psi) at the nozzle (45-100 psi):

(Either enter the average dynamic pressure for the rotor on one zone or enter the average dynamic pressure for all the rotors on the entire system. If the dynamic pressure is not available, enter the system's static pressure. The static pressure will overstate the water savings, but it will still provide an estimate of the potential water savings.)


Enter the GPM @ 45 psi: 

(If you entered the pressure for one zone above, enter the GPM for that zone. If you entered the pressure for the entire system above, enter the GPM for the entire system).


Enter Average Watering Time per Day (min.):


Enter Average Number of Watering Days per Week:


Enter Average Watering Weeks per Year:

The initial system waste is:


The yearly water savings is:


(Due to varying conditions, your actual water savings may be different.
