Hunter Pro-Spray PRS

Hunter Pro-Spray PRS sprinkler bodies comply with new mandates for pressure regulation

Throughout the nation, state legislatures and regulatory agencies are increasingly mandating the use of pressure-regulated irrigation products to maximize water-use efficiency.

To meet these stringent new requirements for water conservation, irrigation product manufacturer Hunter Industries offers a full suite of pressure-regulated Pro-Spray sprinkler bodies — the first in the industry to be WaterSense Certified by the U.S. Environmental Protection Agency (EPA).

Several states and the District of Columbia have introduced pressure regulation requirements for irrigation spray bodies offered for sale that comply with the water efficiency and performance criteria of the EPA WaterSense Specification for Spray Sprinkler Bodies:

  • Vermont: Sold on or after July 1, 2020
  • California: Manufactured on or after October 1, 2020
  • Colorado: Sold on or after January 1, 2021
  • Hawaii: Sold on or after January 1, 2021
  • Washington: Manufactured on or after January 1, 2021
  • Massachusetts: Sold on or after January 1, 2022
  • Washington, D.C.: Sold on or after March 15, 2022

To help comply with these mandates, Pro-Spray PRS30 and PRS40 sprinkler bodies from Hunter Industries have built-in pressure regulation technology that saves up to 30% more water compared to systems without pressure regulation. Brown and gray caps make the products quick and easy to identify for compliance. 

Pressure-regulated Pro-Spray PRS30 and PRS40 Sprinkler Bodies provide a range of benefits, including the same body across all models for easy retrofits, a co-molded wiper seal for leak-free operation even with a loose cap, and optional FloGuard technology for additional water savings in the event of a missing nozzle.
