Testing your irrigation (video transcript)

This is a transcript for our animation that explains how to test your irrigation to check for leaks.

Irrigation systems are the biggest water guzzler in the home! Irrigation can use up to 130 litres of water per minute, or over 5,000 litres per week. This equates to 260,000 litres per year, which is the same as filling up almost 5 swimming pools – imagine how much that might cost!

You can test your irrigation system if you are worried about possible leaks or faults by following these steps:

  1. Make sure you test on your rostered watering day either before 9am or after 6pm.
  2. Set each watering station to two minutes.
  3. Take a reading of your water meter before running the first station, noting both the black and red numbers. You can use one of our irrigation test card to record the readings.
  4. Write down the reading again once the two minutes has run through, and calculate how much water was used.
  5. Repeat this for all stations.

If one or more of the stations recorded a significantly higher amount of water passing through, then you may have a leak or a fault.

What to do:

  • Replace worn nozzles and broken seals.
  • Check the battery backup of your irrigation system – if the battery has died, or there has been a power blackout, your irrigation system may have re-set itself to a different watering schedule
  • You can contact a Waterwise Garden Irrigator to find and repair leaks or set your irrigation controller.

If the test shows no real change to your water use, you can still save water by reducing your set sprinkler times by 2 minutes per station - see what a difference it makes! You can check the recommended reduced watering times for your sprinkler type on our website.
