Hydro-Rain HRS-200 spray bodies optimize pressure for standard spray nozzles and high-efficiency rotator nozzles. Pressure regulation saves water by controlling flow, reducing misting, and improving distribution uniformity.

Hydro-Rain HRS-200 caps have PR molded into the cap to indicate the presence of pressure regulation. They are also color coded for easy field identification. Light grey for adjustable pressure regulating spray bodies and purple for reclaimed water.

The EPA WaterSense Certification logo is visible on the HRS-200 PR spray sprinkler body boxes along with the date of assembly.
