Rain Bird Y34500 Part Circle Sam Pop-up Rotor

Product Description

The RAIN BIRD Y34500 is a 4-inch part-circle SAM (Seal-A-Matic) pop-up rotor designed for residential and light commercial irrigation systems. The integrated SAM check valve holds water in the lateral line after the zone shuts off, preventing low-head drainage on sloped terrain. This rotor delivers reliable, adjustable arc coverage and is installed by irrigation contractors and landscape professionals during new system builds or retrofit applications. At 0.34 pounds, it is a compact, lightweight head suited for turf and groundcover zones.

This rotor is intended for part-circle coverage zones where full-circle heads would cause overspray onto hardscapes or structures. The 4-inch pop-up height provides clearance for established turf, and the 1/2-inch female inlet threads to standard irrigation laterals. It is well-suited for residential lawns, commercial turf borders, and any installation where preventing low-head drainage is a priority on grades or slopes.

Key Features

• Integrated SAM check valve prevents low-head drainage on sloped installations
• 4-inch pop-up height for use in established turf areas
• Part-circle arc pattern reduces overspray onto non-target surfaces
• 1/2-inch inlet threads to standard PVC or poly irrigation laterals
• Lightweight at 0.34 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement for 4-inch part-circle SAM pop-up rotors with a 1/2-inch inlet in residential and light commercial irrigation systems.

Installation Notes

Installation is performed by licensed irrigation contractors or qualified landscape professionals. Shut off the irrigation system water supply and relieve line pressure before removing or installing any rotor head. Flush the lateral line before threading the rotor onto the swing joint or riser to prevent debris from entering the head. Follow local plumbing codes and manufacturer spacing guidelines for proper zone coverage and head-to-head spacing.
