Product details

Our lawn watering kits provide a complete pop-up sprinkler system for domestic garden lawns. Each kit includes underground pipe, Hunter pop-up sprinklers, swing joints, fittings and tap connection parts, giving you a neat, hidden lawn irrigation system that can be connected to a hosepipe or upgraded with a pump, break tank and automatic controller.

- Designed by irrigation specialists
- Uses professional Hunter sprinklers
- Includes heavy duty underground pipe and fittings
- Can be upgraded with a Water Regulations-compliant pump and tank
- Valve box options for a fully automatic system

Benefits of lawn watering

Nothing looks better in the garden than a lush, green well watered lawn. Regular watering also ensures the grass stays in good condition even during times of warm weather and heavy usage. With a pop up lawn sprinkler system everything is hidden under the lawn with the sprinklers rising out of the lawn when watering. Watering is normally done very early in the morning before the grass is being used.

Lawn watering kit contents

These UK lawn watering kits are designed around high-quality Hunter pop up sprinklers and heavy-duty underground pipe, allowing the sprinklers to be connected neatly below the surface of the lawn.

The radius of pop-up can be adjusted between 4.9m – 11.3m, and its arc between 40 and 360 degrees. For watering larger areas the coverage of the sprinklers must be overlapped. As a guide and depending on the flow and pressure available the SLW3 kit will water an area of 10m wide by 26m at 2.8 bar pressure – download the Sample Sprinkler Layout PDF for more layout ideas. The system requires minimum recommended pressure of 1.7bar.

Kit	Sprinklers	Pipe included	Best for	Coverage (Full Circle)
SLW2	2	25m	Smaller lawns	9m x 16m
SLW3	3	25m	Larger single-zone lawns	9m x 24m
SLW6	6	2 x 25m	Larger lawns / two zones	17m x 24m

SLW2 – includes 25m of 20mm pipe, tap connector, 2 pop-up sprinklers with interchangeable nozzles, 2 swing joints, adjustable key for pop-up and compression fittings.
SLW3 – includes 25m of 20mm pipe, tap connector, 3 pop-up sprinklers with interchangeable nozzles, 3 swing joints, adjustable key for pop-up and compression fittings.
SLW6 – note this is two kit SLW3 kits. The maximum number of sprinklers that can be run on a single line is 3. Run SLW6 as two separate watering zones.

Options for your lawn watering irrigation kit

To comply with the UK Water Regulations a pump and break tank are normally required with a pop up lawn watering kit; these also have the benefit of boosting the pressure for the irrigation system, ensuring the sprinklers throw the water the correct distance. To create a fully automatic lawn watering system, an irrigation controller can be added to the pump and tank unit.

Automating your pop up lawn watering kit

The turf, grass and lawn pop up irrigation kit can be automated with a range of mains operated controllers or battery operated controllers. An auto sprinkler system saves hours of time and ensures the watering takes place a night when the evaporation levels are lowest. If a new lawn is being laid, an underground valve box can be incorporated into the design, allowing multiple areas to be watered from a single controller.

Battery controllers have the advantage that they are easy to install – the controller just fits into the valve box and works well if you just have one or two irrigation zones. Mains controllers will operate more valve boxes and have the advantage that they can be Wi-Fi controller, but they need a low-voltage (24 volt) multi-core cable to be run from each valve box back to the controller location. If you have a pump and tank unit, the controller can be pre-fitted onto the tank – please ask when ordering.

Frequently asked questions

Which lawn watering kit do I need?

The right kit depends on the size and shape of your lawn and the water pressure and flow available. As a guide, the SLW2 is suitable for smaller lawns, the SLW3 is suitable for larger single-zone lawns, and the SLW6 is designed for larger lawns or two separate watering zones.

How many pop-up sprinklers can I run on one line?

The number of sprinklers that will run from the water mains depends on your pressure and flow available. As a general rule, a maximum of three sprinklers should be run on a single line. The SLW6 kit should therefore be installed as two separate watering zones rather than one line of six sprinklers.

What water pressure do I need?

The minimum recommended pressure is 1.7 bar – however this is the pressure needed at the sprinkler head – you will need just over 2 bar available at the tap itself as there are some pressure losses in the pipework.

The sprinkler will throw further if there is more pressure – as a guide, the SLW3 kit can water an area of approximately 10m x 26m at 2.8 bar. The ‘Layout Drawings’ PDF shows layouts for both 1.7 bar and 2.8 bar.

How do I measure my water pressure?

You will need a pressure gauge to measure the available water pressure. It is important to test the pressure while water is flowing, not just when the tap is closed. A plumber may give you a static pressure reading, but this is not enough on its own because sprinklers need both pressure AND flow to operate correctly.

Access sells an EPTEST pressure test kit – this has full instructions on how to test the pressure and flow.

Can the lawn watering kit be automated?

Yes. The system can be automated using a mains-operated or battery-operated irrigation controller, with valve boxes used to control different watering zones.

Do I need a pump and break tank?

To comply with UK Water Regulations, a pump and break tank are normally required with a pop-up lawn watering system. This also helps boost pressure so that the sprinklers throw water the correct distance.

How deep should the trenches be?

In a domestic garden, the trenches can usually be around a spade’s depth deep — approximately 300mm.

If you purchase a trenching spade, this will cut a narrower trench, saving work and removing less soil. If the lawn is already established, remove the turf first. If the lawn is large, you can employ a landscape contractor.

How do I plan my sprinkler layout?

Irrigation plan for pop up sprinklers with pencil and compass The downloadable ‘Lawn Layout Drawings’ have a number of pre-drawn plans.

If you want to create a plan for your specific garden, the best approach is to draw a scale plan of the lawn on graph paper and then use a compass to draw out the sprinkler arcs – you need to overlap the sprinklers. A 10m radius sprinkler would be spaced anywhere from 10m apart (known as head-to-head as the spacing is the same distance as the radius) to 13m apart (130% of the radius).
