A Gear-driven rotor with check valve to prevent water pooling at sprinkler sites and 5 interchangeable nozzles for flexibility in system design. See Full Description
The check valve ensures ultimate protection against low head drainage and water collecting at the lowest point in an irrigation system. HydroSure RPS 50 Sprinklers complete with check valve are capable of closing off the valve even up to 3 metres in elevation change.
Time-Proven Patented Reversing Mechanism
HydroSure, in partnership with K Rain’s 35 years of experience, have created a long-lasting pop-up sprinkler system that assures continuous reverse and return without sticking or wear. Features a 4-inch pop-up riser that keeps the rotating nozzle clean and fully operational over time. For ever-changing watering requirements, the stainless steel adjustment radius screw will stand the test of time even after multiple adjustments and the rubber turret cover seals out dirt for increased product durability. The sprinkler also features easy clean mechanisms that can be extracted and cleaned during system maintenance.
Easy Arc Setting
The RPS® features an easily readable indication nozzle arrow that points directly to where the spray pattern is set and the arc can be easily adjusted by turning the RPS key (not included) in the adjustment slot. The sprinkler should be adjusted from the right starting position before adjusting the arc between 40° and 360° with just the simple turn of a riser. The sprinkler arrives with a pre-set 40° arc setting preinstalled with a 1.5 nozzle.
Durable Pop-Up Sprinkler System
Manufactured with a five-year warranty and designed to provide year after year high performance and low maintenance. Engineered from corrosion and impact-resistant heavy duty ABS plastic for superior structural strength and enhanced weatherability for an underground system that can be trusted to last. The stainless steel spring is built for positive retraction of the riser when irrigation is complete ensuring protection against surface damage.
Low-Pressure Pop-up Irrigation System
Functions at optimal pressures between 2.1 – 3.4 bar making it the ideal solution for at-home garden watering and small commercial pop-up irrigation systems.
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 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.
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.
