The See Full Description
Features patented, Triple-Blade Wiper Seal for precisely balanced flushing, flow-by and debris protection to optimize performance and durability at pop-up and retraction. Pressure Regulating to ensure nozzle pressure remains at an average of 2.1 Bar.
The HydroSure Pro S Spray Body is a low-cost alternative that arrives complete with built-in pressure compensation regulating water output regardless of location or elevation whilst reducing water consumption and minimising wind drift.
Product Features
PRS Model Pressure Compensating Sprinkler
Regulating pressure to an average of 2.1 bar, the PRS model features a built-in pressure regulator that increases nozzle efficiency by up to 50% in high-pressure applications.
With pressure regulation built in each emitter will output the same amount of water regardless of location or elevation in the system.
Built-in Flow-Shield technology delivers a low-flow service indication stream when the nozzle is either damaged by footfall.
Seal-A-Matic (SAM) Check Valve
Eliminate water pooling at sprinkler sites, the built-in SAM technology traps water in the lateral pipes even in elevation changes of up to 4.2 metres!
Drainage from spray heads at lower elevations is prevented, reducing water wastage and landscape damage due to flooding or soil erosion.
Triple-Blade Co-Molded Wiper Seal
The pressure-activated wiper seal eliminates flow-by ensuring a water-tight seal enabling more heads installed per zone.
Dual seals flush out the system during pop-up and retraction promising protection against grit and debris entering the sprinkler whilst the primary seal eliminates flow-by.
Features a unique, built-in debris pocket that collects grit, removing it from your system and preventing long-term damage.
Prevents Stick Ups
Engineered to withstand the most challenging landscapes promising optimal performance and unmatched durability at both pop-up and riser retraction.
Built to cope with high operating pressures used in most commercial systems, the Rain Bird 1800 series is made from superior corrosion-resistant steel parts and time-proven UV-resistant plastics.
Easy Sprinkler Alignment
The internal ratchet mechanism ensures easy nozzle pattern alignment without tools. Simply adjust the watering direction by turning the riser by hand.
For long-lasting performance and accurate spray patterns, the ratchet ring is engineered from reinforced materials promising minimal disruption from harsh weather.
No Tools Maintenance
Arrives complete with a Pop-Top Flushing Plug to block debris from entering the sprinkler during system maintenance.
Easily removable without any tools, the flush cap can be simply unthreaded to reveal a male thread for installation of a Rain Bird Spray Nozzles or Spray Heads from leading brands (sold separately).
When flushing the system during and at the end of the watering season, remove the nozzle at the end of a lateral line and replace with a flush cap. Manually turn on the valve to flush the system and re-install the spray nozzle.

Pop Up Spray Bodies Frequently Asked Questions
Why is Water Pooling Around the Sprinkler Site?
Underground systems require frequent flushing to prevent dirt from clogging the nozzle or damaging the seal. Flush the system and clean the rotors if necessary to remove any sitting sediment.
Any damage to the riser caused by a mower or footfall will cause mechanical malfunction and disfigured spray patterns. Check each nozzle and turret on top of your sprinklers to ensure they are intact.
The area around a sprinkler site may become boggy/waterlogged indicating a loose connection between the swing joint/fitting or a break in the pipe network. To repair a leak, use a Compression Joiner, Joiner depending on the pipe used or install PTFE Tape around any male threaded connection to ensure a watertight seal.
Water leaking from sprinkler sites even when the system is switched off indicates a problem called low head drainage. A pop-up sprinkler with a Check valve will prevent water pooling from sprinklers installed at the lowest elevation.
My Sprinklers are not Working the Same as when Purchased!
Over time a sprinkler may experience a build-up of sediment and debris that blocks the nozzle outputs or damages the riser retraction mechanisms inside the sprinkler. Flush the system and clean out the rotor sprinkler as explained in our Sprinkler Maintenance Guide.
Prevent debris build-up by installing an Irrigation Filter at the start of the system. • Alternatively, leaking connections or a pipe supplying the sprinkler may have split. The water lost from connections that are not watertight will cause pressure loss and reduce performance.
Why are my Underground Pipe Connections Leaking?
An area that is boggy or waterlogged indicates a leaking connection or a pipe that may have split. Most connection points can be tightened by hand or by adding two wraps of PTFE Tape around male threads or replacing connectors that over time, have snapped.
When fixing your pipe network, depending on the pipe you are using to supply your system will indicate the type of connector you need to repair the damage.
My Sprinkler Does Not Cover the Range/Radius Outlined in the Specifications
A variation in flow rate or pressure drop from the water source will also reduce the performance of sprinklers – Check the flow rate from your tap remains high enough during the time of day your system is set to run using our Calculating Flow Rate from the Water Source Guide.
On windy days, the spray pattern from your sprinklers may alter even when using nozzles with built-in wind resistance. Alternatively, running a system at a bar pressure that is too high, will create misting – Consider installing a Pressure Reducer regulated as specified in the sprinkler specifications to minimise spray pattern wind drift.
