5 Easy Steps to Calculate Water Savings

Estimated Water Savings Using Pressure Regulated Rotors

In-stem pressure regulator ensures maximum nozzle performance, even with varying inlet pressures. By maintaining constant optimum pressure of 45 psi at the nozzle, pressure regulated rotors end misting and fogging caused by high pressures. For you that means water savings.

Enter the information from your system below and see how much water you can save!

PRB Example

Step 1. Enter the pressure (psi) at the nozzle (between 45 psi and 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.)
Step 2. 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).
Step 3. Average Watering Time per Day (min.):
Step 4. Average Number of Watering Days per Week:
Step 5. Average Watering Weeks per Year:

The initial system waste is:		GPM
The yearly water savings is:		gallons *

* Due to varying conditions, your actual water savings may be different. This formula is designed solely as a basis for estimating potential savings.
