RD1800™ Series Spray Heads
Low-Flow Service Indication Stream
Exclusive Flow-Shield Technology delivers a
low-fl ow service indication stream when a nozzle
is removed. As a result, system performance is
maintained, water is saved and you don’t have to
wait until you have brown grass or dead plants to
notice something’s wrong.
Triple-Blade Wiper Seal
The RD1800™ series features an exclusive
Reclaimed Water Resistance
Triple-Blade Wiper Seal. The top seal ushes during
pop-up and wipes the stem clean during retraction,
preventing external debris
from entering. During
operation, the primary seal
combines with the stem’s
surface to eliminate fl ow-by.
The exclusive third blade
provides another line of
defense, in case the primary seal is damaged.
Reinforced Ratchet Mechanism
The RD1800’
s ratchet mechanism was designed
to improve ease of use and consistenc
y, hold its
setting over time, withstand years of chlorine
exposur
e and provide greater debris resistance.
Unique Debris Pockets
With each system start-up,
the RD1800’s unique
debris pockets hold grit in
place—removing it from
circulation and preventing
long-term damage.
