This tough-to-beat Rain Bird sprinkler is ideal for installation on sloped layouts. The built-in Seal-A-Matic technology is capable of holding water within the system even up to 2.1m of elevation change.
For a low-cost alternative, the HydroSure Mini Pro Rotor arrives complete with check valve to prevent water pooling at sprinkler sites up to elevation changes of an impressive 3 metres!
Seal-A-Matic Check Valve
Holding up to 7 feet (2.1m) of elevation change to prevent puddling and erosion caused by low head drainage, the 3500 series rotor with SAM technology keeps water within the system after switch off.
Uniform Spray Patterns
Consistently keep your lawn green and healthy whilst using less water – Save water and money!
Complete with six Rain Curtain Nozzles to deliver water with superior distribution and uniformity over the entire radius.
Each nozzle is engineered with Rain Curtain technology to emit large water droplets resistant to misting and evaporation.
Gentle, close-in watering eliminates dry spots around the rotor, prevents seed wash out and ensures water is delivered to the right place.
Oversized Wiper Seal
The multi-functional wiper promises a durable, leak-free seal and protection for the internals against debris.
Not only does the Rain Bird wiper seal promise 2x the sealing surface of the leading competitor, but its pressure-activated design also prevents puddling and guarantees pop-up retraction every time.
Sprinkler Performance
Capable of outputting a radius between 4.6 to 10.7m, the reversing full and part-circle operation emits an adjustable arc between 40º - 360º
The self-cleaning adjustment screw allows you to reduce the radius by up to 35% so the watering pattern does not overthrow the required watering area.
Arc factory setting at 180º for convenience.
To adjust the arc, use the Rain Bird Rotor Adjustment Tool (not included).
Long-Lasting Features
With proven performance, Rain Bird rotors have a 13-year reliable history tested in millions of operations.
Features an easily removable filter screen for simple maintenance and prevents the drive from clogging.
The internal stainless steel retraction spring guarantees positive pop-down.
Providing an exposed surface area of 2.9cm, the rubber turret cover prevents debris from entering the unit.
Complete with a water-lubricated gear drive for ultimate durability without wear.
Specification
Operational Pressure Range: 1.7 Bar to 3.8 Bar (100 to 380kPa)
Precipitation Rate: 0.37 to 0.83 inches per hour (9 to 21mm/h)
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 /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 anIrrigation 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.

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.
How do I Lift the Riser of a Pop-up Sprinkler?
To lift the riser of a rotor sprinkler, most require a Key inserted into the turret top of the sprinkler to lock into the mechanism and allow easy uprooting of the riser by hand. Any maintenance or switching of nozzles is often carried out in this way. Alternatively, ask a friend to switch the system on manually and catch the riser as it lifts during system operation.
