HERE’S WHAT OUR CUSTOMERS ARE SAYING ABOUT PRECISION
™
SERIES SPRAY NOZZLES!
“I was skeptical that putting 30% less water down
would keep the turf in good condition. If I reduced
my time by 30% with the old nozzles, I’d be growing
straw. All I can say just by my observation is that it
works. So far it looks great.”
Bill Bobbit

“We are finding that with the new water windows,
if you have the old-style nozzles or high-eciency
competitive nozzles, you cannot complete your wa-
ter cycle to meet a water district’s water window.”
Eric Anderson

“For us, usually it’s not about pressure, it’s about the
volume of water available. There was one job where
I was going to install four valves, 2 in front and 2 in
back, with these nozzles, I was able to use just two
valves, 1 in front and 1 in back, and cut my cost in
pipe and valves in half.”

1” PER HOUR MATCHED PRECIPITATION AND ONE-FOR-ONE RETROFIT
Perfect when upgrading conventional, higher flow spray nozzles…Look for the “O” stamped on top of the nozzle.
HIGHER OVERALL IRRIGATION EFFICIENCY FROM 4-15 FEET
Precision Series Spray nozzles perform more like a small rotor. The H²0 Chip enables the nozzles to achieve distances of throw
equivalent to those of conventional spray nozzles – but with one-third less flow and higher overall irrigation eciency.
We ensure that our research is unbiased when we
make tests. We have seen a uniformity coecient
greater than 80% on the Precision Spray Nozzles,
which we’ve never had on square spacing.”

“DU before the swap was 44%. After changing to
Precision Spray Nozzles (No other changes or adjust-
ments were made), DU went up to 73%. An increase
of 29%! Using the 2009 YTD ET/Rainfall data, this
could represent a savings of almost 11,000 gallons
for this single zone!”

“I am absolutely thrilled by the installation of the
Precision Spray Nozzles. I am getting water where
the gardener said I never would. I asked him to com-
pletely do my back yard with these nozzles. I live in
an area that we can only water three days a week.
But every inch of my backyard now gets watered.
And even though it’s been hotter than blue blazes,
my lawn is greening up.”

“What I found in general was they had a much higher
uniformity than regular spray nozzles. They were
also consistently at about a 25% less application
rate overall, compared to regular spray heads. Run-
ning these nozzles side by side with regular nozzles
they keep the lawns green in the same number of
minutes with these using less water. Because these
nozzles are proving to have a better uniformity rate,
you can cut down the amount of time and still have
the same results.”
