Pro-Spray® PRS Spray Sprinklers Meet New State Mandates for Pressure Regulation

Tuesday, December 7, 2021

Across 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 spray bodies — the first in the industry to be WaterSense Certified by the U.S. Environmental Protection Agency.

Several states 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
  • Maine: Sold on or after January 1, 2021
  • Massachusetts: Sold on or after January 1, 2022
  • Washington: Manufactured on or after January 1, 2021

To help comply with these mandates, innovative Pro-Spray PRS30 and PRS40 spray 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 spray sprinklers 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 a factory- or field-installed check valve for added flexibility.

“We are all responsible for using water efficiently while supporting the development of green infrastructure,” said Kelsey Jacquard, Senior Product Manager. “We’re proud to provide the most advanced and comprehensive water-saving solutions in the landscape irrigation industry.”

The complete offering of Hunter Pro-Spray PRS spray sprinklers is available on the EPA WaterSense website and
