elevation changes up to 14’ (4.2 m). One of
the strongest springs in the industry.
• Prevents drainage from spray heads at
lower elevations. Stops water waste. Ends
landscape damage due to ooding and/
or erosion.
• Helps retain water in lateral pipes which
reduces wear on system components by
minimizing water hammer during
start-up.

1800 PRS Series
Designed for areas with high and/or widely
uctuating water pressures, the 1800 PRS
Series has all 1800 Series features plus:
• PATENTED PRS pressure regulator built
into the stem. No parts to be installed at
the site. Saves time and money.

30psi (2.1 bar). Spray nozzles perform
best at 30psi. Ensures maximum nozzle
performance, even with varying inlet
pressures. Maintains constant pressure
regardless of nozzles used.
• Restricts water loss by up to 70% if nozzle
is removed or damaged. Saves water and
money. Reduces possibility of accidents
and property damage. Recommended for
vandal-prone areas.
• Ensures consistent performance
throughout zone if nozzle is removed or
damaged. Keeps plant life covered by
other spray heads properly irrigated.
• Ends misting and fogging caused by high
pressure. Stops water waste. Ensures
