Did you know that different types of sprinklers have different watering rates? Check the best setting for your sprinkler system.

Ensuring your irrigation system is not over watering your garden and lawn can save a lot of water!

Use the videos below to find the recommended run times for watering your garden, depending on which sprinklers you have, or to find the best sprinkler type for your gardens needs.

Seasonal sprinkler run times

As the seasons change, so do the water needs of your lawn and garden. The table below shows the adjustments that should be made to your irrigation controllers ‘Seasonal Adjustment’ setting to avoid over watering.

No matter what the season, your controller should always be turned off when it’s raining.

Testing your sprinkler application rates

Catch cups (graduated measuring containers) are a valuable tool for testing how efficiently an irrigation system is operating and the sprinkler application rates.

To test, you should:

  • spread catch cups or containers of the same size randomly around the watering zone
  • make sure they are at least 1 metre from the closest sprinkler
  • time how long it takes the sprinklers to fill the catch cups to the depth of 10mm – this is the standard drink for an area of sandy soil.

Once you have your reading, adjust your irrigation controller to allow for a standard drink of 10mm using the time taken to fill the cups.

Uneven results?

If there is a significant variation in the depth of water captured by the catch cups then your sprinkler system is not applying the water evenly and should be checked for design or maintenance faults. If you need help with this, find your closest Waterwise Garden Irrigator or Waterwise Irrigation Design Shop.

Once the faults have been corrected run the test again to determine how long to run your sprinklers to deliver the recommended application rate.
