Rain Bird Xerigation RETRO-1800 - Drip Conversion Kit for 1804/1806/1812 Spray Heads

Transform spray zones into efficient drip irrigation

The Rain Bird 1800-RETRO Xerigation retrofit kit is designed to simplify converting a conventional spray zone into a low-volume drip setup. By dropping inside compatible spray heads, this kit helps you switch to drip tubing without extensive re-piping. It’s compatible with Rain Bird 1804, 1806, and 1812 spray bodies, making a retrofit straightforward for many existing irrigation layouts.

With its compact internal assembly, the retrofit integrates cleanly into your current system. The result is a streamlined path from your supply line to drip tubing, enabling more precise water delivery where you need it most.

Key benefits

• Permits convenient conversion to drip tubing when used with compression adapter.
• Provides 30 psi pressure regulation and a 200-mesh (75 micron) screen.
• Internal assembly drops into any 1804, 1806, or 1812 spray head body.
• If retrofit flow is less than 3 GPM, replace electronic valve with Rain Bird Control Zone Kit.

How it helps your garden or landscape

Where you once relied on spray zones, you can explore a gentler, more controlled drip approach that targets root zones and plant beds. The kit’s pressure regulation helps avoid overwatering in delicate plantings, while the 200-mesh screen helps reduce debris entry. The compact fit means less clutter around your sprinkler head and easier maintenance over time.

What’s included and compatibility

• Internal assembly compatible with 1804/1806/1812 spray heads.
• Low-profile 1/2" FPT x Barb Elbow fitting and 1/2" FPT x Barb Tee fitting for easy drip tubing connections.
• Designed to support flow rates from 0.5 to 6 gpm.

Consider this retrofit as a flexible option for mid-season irrigation adjustments. If your retrofit flow approaches the lower end of the range, you may want to explore zone control options from Rain Bird for optimized performance.
