RD1800 Series Spray Heads

Robust design for harsh applications

Every landscape has elements that wear on your spray heads over time—from sand and grit to high water pressure and harmful chemicals in reclaimed water.

RD1800™ was designed with these incredibly harsh conditions in mind. As the next evolution in spray heads from Rain Bird—the industry leader in sprays—RD1800 was built with exclusive materials and features that stand up to the challenges of any setting (see Features below for more information about what sets the RD1800 apart)
