# 5 Easy Steps to Calculate Water Savings

## Estimated Water Savings Using Rain Bird® TSJ-PRS Series Pressure Regulating Swing Joints

Rain Bird's TSJ-PRS Series Pressure Regulating Swing Joints control and maintain pressure for rotors with 3/4" and 1" inlets. In very high pressure or fluctuating pressure situations, the TSJ-PRS ensures optimal droplet size and eliminates misting, resulting in improved uniformity and reduced water consumption. For you that means water savings. Enter the information from your system below and see how much water you can save.

 Calculate your estimated cost savings: Please select a TSJ-PRS Series Model:   TSJ-075-PRS (45 psi) TSJ-100-PRS (70 psi) Step 1: Enter the pressure (psi) at the rotor inlet:   (Either enter the average dynamic pressure for the rotors 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:  (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: Enter Average Watering Time per Day (min.): Step 4: Enter Average Number of Watering Days per Week: Step 5: Enter 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.
