Components included:
3 x Hunter PRS-40 2.8 Bar Pro Sprays - 4" Pop-Up Sprinkler with Check Valve
A strong and versatile spray body promising years of reliable performance.
Engineered with built-in pressure compensation to regulate water pressure to a constant 2.8 bar for optimal nozzle performance enabling uniform and consistent coverage.
The included check valve eliminates water pooling at sprinkler sites located at the bottom of a slope. Once the system is switched off, it keeps the water within the pipe network and protects the landscape from damage and erosion whilst reducing water wastage.
3 x Hunter Swing Joints 1/2" x 1/2 " - 12" Long
For ultimate flexibility when placing your sprinkler head at its sub-surface location, this swing joint enables easy routing of sprinkler heads at any angle from the lateral pipe.
3 x HydroSure Tee Compression Couplings Female 25mm x 1/2" x 25mm
Enabling an easy one-step installation process, this compression tee fits standard-sized 25mm MDPE & HDPE pipe. Promising a watertight connection and a smooth internal bore for maximum water flow, this fitting helps to enhance emitter performance by limiting pipe friction.
PTFE Thread Seal Tape
No more time-consuming installation! Each male thread has been wrapped with PTFE tape for secure irrigation joints and ultimate protection against leaking connections.

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 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 or Barbed 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.
