Product Overview

The Pressure Regulated spring-loaded pop-up with an Eco-Stream nozzle is setting a new standard for water efficiency in the turf & landscape industry. The multi-trajectory, rotating streams of the Eco-Stream Rotator apply water more slowly and uniformly than conventional sprays and rotors. The added pressure regulator ensures that each head sprays consistently (regardless of pressure) and reduces water waste from fogging. Fully adjustable spray distance from 8 ft. to 15 ft. and pattern adjustment 90 to 210°.

  • Ideal for watering lawns and gardens
  • Even watering for a lush green yard
  • 40 psi regulator - eliminate overspray and misting
  • Adjustable from 90 to 210°

Customer Questions & Answers

What is the GPM of these nozzles?

at 180 degrees and at 90 degrees
Asked by: PL
PL, that will depend on your water pressure. For the sake of this discussion, we'll operate under the assumption that your water pressure is 40 PSI. With a 180 degree spray arc, your sprinkler would use 0.37 GPM (with a spray radius of 14 feet). A 90-degree spray arc would use 0.19 GPM (with a spray radius of 14 feet). If you'd like further information, please feel free to contact our Support team at 1-800-488-6156. We'd be happy to help. Thanks!

Is this the pressure activated sprinkler for use on slopes or hills; once it stop no more water will run off?

Asked by: Rd
Rd, this pressure-regulated sprinkler ensures that the nozzle will not receive pressure over a certain range. If the flowing line pressure is over 45 psi, the head has a pressure regulator that will drop the pressure to 40 psi (+/- 5 psi). It cannot raise the line pressure if the pressure is lower than 40 psi, but it will prevent the sprinkler from getting too much pressure. To answer your other question, this specific sprinkler model does not have a check valve feature to prevent run-off on hills or slopes.

Customer Reviews

4 in. Adjustable Pattern Pressure Regulated Pop-Up Sprinkler with Eco-Stream Nozzle is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Work well. If you need sprinkler heads to cover lawns that do not have 90 degree corners these will do the job. I have used an earlier version of these heads for years and they give really good coverage for curved edges. They are easy to set up and provide uniform water distribution even without overlapping coverage.
