Hunter Industries PROS04PRS40 Pop-up Sprinkler 4in 40psi

Product Description

The HUNTER INDUSTRIES PROS04PRS40 is a 4-inch pop-up sprinkler body with an integrated 40 psi pressure-regulating module, designed for residential and commercial irrigation systems. The built-in pressure regulator maintains consistent downstream pressure at 40 psi regardless of inlet pressure fluctuations, protecting nozzles from misting and overspray caused by excessive line pressure. This body accepts standard Pro-Spray compatible nozzles and is installed by irrigation technicians and licensed landscapers as part of a zone-level spray head layout. It is a core component in low-volume, efficient turf and shrub irrigation designs.

The PROS04PRS40 is suited for residential lawn irrigation zones, commercial landscape installations, and retrofit applications where high inlet pressure is a recurring issue. The 4-inch pop-up height positions the nozzle above short turf and ground cover during operation, then retracts flush to grade when the zone is off, reducing mowing interference and trip hazards. It is typically installed in zones designed for fixed or adjustable spray nozzles.

Key Features

• Integrated 40 psi pressure-regulating module controls downstream pressure at the head level
• 4-inch pop-up height suits standard turf and low ground cover applications
• Retracts flush to grade when zone is not active, minimizing surface obstruction
• Compatible with Pro-Spray series nozzles for flexible coverage patterns
• Helps reduce misting, fogging, and uneven distribution caused by high system pressure

Compatibility

Designed as an OEM-style replacement or new-installation sprinkler body compatible with Pro-Spray series nozzles used in residential and commercial irrigation systems.

Installation Notes

Installation should be performed by a qualified irrigation technician or licensed landscaper in accordance with local plumbing and irrigation codes. Shut off the irrigation zone valve and relieve line pressure before removing or installing any sprinkler body. Use Teflon tape on threaded fittings and avoid overtightening to prevent body cracking. Verify nozzle selection and arc adjustment after installation before returning the zone to service.
