The RAIN BIRD A46610 is a non-potable snap-on cover designed as a replacement top cap for the 1800-NP series pop-up sprinkler heads used in non-potable water irrigation systems. This cover snaps directly onto the sprinkler body, providing a secure fit without tools. Its purple color coding follows industry convention for reclaimed and recycled water systems, allowing field technicians and inspectors to quickly identify non-potable zones at a glance. Irrigation contractors and landscape professionals install this part during sprinkler servicing, zone conversions, or system upgrades where compliance with local reclaimed water regulations requires proper component identification.
This snap-on cover is intended for use with RAIN BIRD 1800-NP series pop-up sprinkler heads installed in residential and commercial landscape irrigation systems operating on reclaimed, recycled, or non-potable water sources. It is a common replacement item during routine maintenance when existing covers become cracked, faded, or lost. Proper use of purple-coded components is often required by local water authority codes governing the use of reclaimed water in irrigation applications.
Designed as an OEM-style replacement snap-on cover for RAIN BIRD 1800-NP series pop-up sprinkler heads used in non-potable water irrigation systems.
Installation is performed by irrigation technicians or licensed landscape irrigation contractors. Before servicing any sprinkler head, shut off the irrigation zone valve and confirm the system is depressurized. The snap-on cover aligns with the sprinkler body collar and presses firmly into place by hand. Verify that the cover is fully seated and that no debris is caught in the snap joint before restoring system pressure.
