RD1800™ Series Spray Heads

Tough enough for your most challenging landscapes

Rain Bird RD1800 Series Spray Heads

Legislation, growing demand and a limited potable water supply have increased our reliance on alternative water sources. As a result, water used for irrigation is harsher today than ever before. You told us you need a spray specifically suited for the most challenging environments. You also want a spray that will conserve water and provide years of worry-free performance. The new Rain Bird® RD1800™ Series Spray is proof that we’ve been listening.

The Rain Bird RD1800’s exclusive Triple-Blade Wiper Seal prevents stick-ups. Its innovative design handles the thickest grit and most dramatic pressure variations with ease and its exclusive Flow-Shield™ Technology helps you identify and solve problems faster.

The Rain Bird RD1800 is available in both potable and non-potable versions.


RD1800 Triple Blade Wiper SealTriple-Blade Wiper Seal - With a patented Triple-Blade Wiper Seal that precisely balances flushing, flow-by and debris protection, RD1800 optimizes performance
and durability in all soil types.

Flow-Shield™ Technology - If a nozzle is ever broken or removed, patented Flow-ShieldTM Technology saves water by creating a low-flow service indication stream, letting you know there’s a problem before things get bad.

Unique Debris PocketsDebris Pockets - Debris pockets in the base of the spray collect debris and grit to prevent recirculation, which provides a longer life. So, when other stems and nozzles become clogged with grit, the RD1800 remains clear.

Chlorine- and Chemical- Resistant Materials - Exclusive models designed for non-potable water are made from the same durable plastics that are used in swimming pools, to outlast the unique challenges of recycled and reclaimed water. (Non-potable models only.)

Patented Purple Cap - Featuring the international Do Not Drink symbol and warnings in English and Spanish right on the cap, RD1800 eliminates the need for bulky clip-on warning caps. (Non-potable models only.)

Five-year trade warranty.
