Popup Lawn Sprinklers
How do pop-up sprinklers work?
All the pipes and sprinkler heads are buried beneath the turf surface, completely hidden away keeping your lawn looking neat and tidy. When the system is turned on, the pop-up sprinklers rise from beneath the ground and then retract back down when the system is turned off, usually by an automatic timer.
What are the required components?
- Back-flow prevention device
- Popup sprinkler body
- Swing arms
- Low density poly pipe
- Low density fittings
- Irrigation Controller
For a larger lawn (greater than 10 m x 10 m) we recommend the Hunter PGJ, PGP, I-20 and I-25 sprinklers. They come complete with a range of nozzles that spray from 5 metres distance with a 0-360 degree adjustable arc coverage.
For a smaller lawn (less than 10mx10m) we recommend the Hunter ProSpray Pop ups and MP Rotator nozzles . There is a large range of rotator nozzles that can spray from 2.5 m to 10.7 m radius and various adjustable and no adjustable arcs.
Before you get started there are a couple of things you need to do:
- Measure your water flow rate from the water source you will be using. We can hire our a flow meter for you to measure your flow rate if you're not sure how.
- Draw a plan of the area you want to water to map out where your pop ups will be placed.
For more information on flow rate and drawing plans please click here.
When selecting nozzles, "Head to Head" coverage of sprinklers is important, they should be installed so that one sprinkler sprays onto the adjacent sprinkler.
Please see the drawing below which shows a 10m x 5m lawn area with 6 sprinkler heads.
It is better to spray from the edge of the lawn inwards to eliminate spraying hard surfaces. If the area is wider than the radius of the sprinklers used, then more sprinklers should be placed in the middle of the lawn.

Swing Arms or articulated risers are a great component to help adjust the height of your sprinkler body and get into corners without the extra digging.
Pipe - You will need to dig a trench around your lawn area to lay the low density pipe that will be connected to your main water source. The pipe size we recommend for domestic lawns is 19 mm (3/4") low density poly pipe.
Connect your sprinklers to the main line with low density fittings and then adjust and tune the nozzles to make sure they are spraying in the right direction and to the correct distance.
Smart Control - We recommend installing an irrigation controller that connects to a local weather station and automatically adjusts to the local weather conditions (see "Installing an Irrigation Controller") or tap timer with a rain sensor that will turn your system off when it is raining.
