Rain Bird B65521NP Falcon 6504 Pop-up Rotor 4 Inch

Product Description

The RAIN BIRD B65521NP is a Falcon 6504 series pop-up rotor sprinkler head built for professional irrigation installations. This unit features a 4-inch pop-up height, a pressure-compensating (PC) internal assembly, a stainless steel (SS) riser, and a non-potable (NP) designation, making it suitable for reclaimed or recycled water systems. The 1-inch inlet connection accommodates standard commercial and residential mainline sizing. Irrigation contractors and landscape professionals install this rotor in turf and large-area coverage applications where consistent distribution uniformity is required across varying inlet pressures.

This rotor is designed for large turf areas, sports fields, parks, and commercial landscape zones where uniform water distribution across wide radii is a priority. The pressure-compensating feature helps maintain consistent output even when system pressure fluctuates across zones. The stainless steel riser provides added durability in high-traffic or abrasive soil environments. The non-potable designation and typically purple or marked components signal compliance with reclaimed water system requirements where applicable by local code.

Key Features

• 4-inch pop-up height for coverage above dense turf canopy
• Pressure-compensating (PC) design maintains consistent flow across variable inlet pressures
• Stainless steel (SS) riser construction for enhanced durability and corrosion resistance
• Non-potable (NP) rated for use in reclaimed or recycled water irrigation systems
• 1-inch inlet connection compatible with standard commercial mainline piping

Compatibility

Designed as an OEM-style component within the RAIN BIRD Falcon 6504 rotor series for professional large-turf irrigation systems.

Installation Notes

Installation should be performed by a licensed irrigation contractor in accordance with local plumbing and irrigation codes. Shut off system water supply and relieve line pressure before replacing or installing the rotor head. Verify that the irrigation zone is designated and plumbed for non-potable use before installing NP-rated components, as mixing potable and reclaimed water lines may violate local code. Use pipe thread sealant rated for irrigation fittings on the 1-inch inlet connection.
