Calculate Cost Savings in 5 Easy Steps

K-Rain's super rugged and durable Pro S Sprays with in-stem pressure regulation ensures maximum spray head and nozzle performance, even with varying inlet pressures. By maintaining constant optimum pressure of 30 psi at the nozzle, the Pro S Spray heads eliminate misting and fogging caused by high pressures. That equals both water and cost savings. Enter the information from your system below and see how much water and money you can save:

Calculate your estimated cost savings:  
Step 1: Enter Nozzle Pressure (psi):

(Either enter the average dynamic pressure for the spray heads on one zone or enter the average dynamic pressure for all the spray heads 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 cost savings.)

Step 2: At 30psi 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: Watering Schedule (All 3 fields required):
 
  Average Watering Time Per Day (min):
  Average Number of Watering Days per Week:
  Average Watering Weeks per Year:  
Step 4: Select on of the unite Water Costs:  
  Unit Water Cost ($ per 1000 gallons): $
  Unit Water Cost ($ per HCF or CCF):     $
Step 5: Number of Sprinklers heads in a zone:  
  Cost difference between the K-Rain RN200 and other Rotary nozzels: $ per unit
     


The estimated water savings is:   GPM
The estimated yearly water savings is:   gallons
The estimated yearly cost of water savings is*: $
The estimated cost of upgrading to 1800 PRS is:  $
Estimated Payback Time:   years
months

*(there are many different conditions that can effect the actual cost savings.  Your Potential cost saving is only an estimate).
