A lawn sprinkler helps you water your garden. For large areas, several sprinklers can be connected in series. You can find the how-to in our instructions in a simple and understandable way.

In a nutshell

  • frequent pressure loss in the course of a series connection
  • Lawn sprinkler with inputs and outputs suitable for direct passage of the supply line
  • more even pressure supply of the series connection by adjusting the configuration

Series connection explained

Daisy-chaining your sprinklers means you're using a single line that feeds all of the individual irrigation elements in tandem. All objects are controlled one after the other, so that a schematic representation ultimately depicts the eponymous row.

Notice: Of course, the sprinklers can easily be placed anywhere in the garden. Only the supply takes place via a single line because of the sequence.

Which lawn sprinklers can be used?

In principle, all types of lawn sprinklers can be connected in series, regardless of the way the water is distributed. However, some models have a great advantage for the series supply: In addition to the input for the supply line, they also have an output. For models without this feature, you must use an auxiliary construction described in Variant 2 of the instructions for switching in a supply row.

Instructions: Switch lawn sprinklers in series

Now let's look at how you can easily daisy chain your lawn sprinklers together.

Standard variant: "Real" series connection

"Real" series connection of lawn sprinklers

The basic requirement for a real row of all lawn sprinklers is that your model has an inlet and outlet. All objects can then be connected using line segments and set up in a series connection:

  • first position sprinklers at desired locations in the garden
  • Determination of the line route, ideally the shortest possible connection paths between the supply and sprinkler 1, sprinkler 1 and sprinkler 2,…
  • Remove drain plugs from all sprinklers except the last one
  • Connect water supply and sprinkler with pipe segments
  • Check that the connections are secure and correctly closed
  • Carry out a function test by releasing the water and, if necessary, adjust the position and alignment of the sprinklers

Tip: Some leaks only become visible after long-term operation, for example due to damaged seals that are temporarily still working. Therefore, carry out another visual inspection after the first few hours of operation.

Variant 2: Central supply line

With little effort, the supply structure described can be applied to lawn sprinklers without a separate line outlet on the one hand, but can also be optimized with regard to optimum pressure in the entire system on the other. For this purpose, instead of a supply line looped through the sprinklers, a central line is set up, from which branch lines branch off to the individual sprinkler elements:

  • Specify sprinkler locations
  • Define the course of the supply line with the passage of all sprinklers
  • connect a short branch line to each watering object
  • Equip the free ends of these stub lines with a T or Y piece
  • Set up the supply line using line segments: water connection to sprinkler 1, sprinkler 1 to sprinkler 2,…
  • Check the system for function and leaks by means of supervised commissioning

Variant 3: ring line as an improvement

Lawn sprinkler with ring line

Depending on the cross-section of the line, the length of the line and the number of garden sprinklers connected, both the real series connection and the supply via a central supply line can have the effect that the pressure decreases from sprinkler to sprinkler. The effect can be observed directly in the garden. The lower the pressure, the shorter the range of the lawn sprinkler. As a result, identical objects cover smaller and smaller areas of the garden as soon as you connect them in series. A simple addition that expands the series connection to a ring line promises a remedy:

  • Connect end of line to hose segment (last sprinkler or last fitting of service line)
  • Return hose segment to water supply
  • Establish a connection using a T-connector

Now your irrigation system is supplied with water from both sides, so that there is a much more constant water pressure in the entire irrigation row.

Notice: Extremely long ring mains can still show a pressure drop with increasing distance from the supply. However, the system dimensions required for this should be rather unusual in domestic gardens.

frequently asked Questions

What are pressure-regulating lawn sprinklers?

These sprinklers have a simple pressure limiter themselves. In this way, the line pressure can be increased without changing the preset range. The result is the possibility of being able to offer the same usable water pressure on every object, even in long rows. These sprinkler types actually make it unnecessary to expand the row to form a ring line.

What is the alternative to the supply chain?

An example of an alternative supply option to the real supply series or the ring line is the star-shaped structure. A distributor is placed directly at the water connection, from which each garden sprinkler is supplied with the same amount of water via its own line.

Is the series supply suitable for permanent installation?

The water supply for your lawn sprinklers can be installed both temporarily and permanently in the form of a series system. Especially in the case of the version with a central line and branches per sprinkler, however, the effort is comparatively high, so that this design appears to be particularly suitable for permanent installations of fixed irrigation systems.
