  • Step 1. Install a water saving dripper system

    If you are tired of hand watering your garden, install a water saving dripper system and you won't even have to turn on the tap.

    Dripper systems are low cost, easy to install, and easy to use.

  • Step 2. Saving water

    A dripper system, if properly installed, can use a fraction of water than sprinklers that produce a fine spray. Having the water drip directly onto the plant roots in the garden bed and shrubberies reduces the effect of water wastage due to wind and overspray. These systems are low cost, easy to install and easy to use.
  • Step 3. Plan out your garden

    You need to determine how much tubing is required by drawing an outline of your garden including features such as your house, taps and what plants are where.

    A quick drawing of the layout of the area you want to irrigate & dash; showing house location, north garden bed, approximate measurements, plant types and tap location.

  • Step 4. Install your system

    To install your watering system, unroll the tubing and let it unkink in the sun. Following your system plan, lay out the tubing and other components near where they'll be used. Make sure you fit a backflow valve to all taps you'll be using on the watering system - these are compulsory in some states. This should stop contaminated water from flowing into your household irrigation pipes. Areas with high water pressure may require a pressure reducing valve.

    Once you have finished, make sure you flush the system to remove debris which could block the flow of water. Once flushed, attach the stopper to the end of the tube.

    Connect your tap timer to the tap then connect it to the driptube, then set the program.Your system will now operate automatically.

    Lay pipe in a grid formation 300mm apart.

  • Step 5. Automation

    There is a wide variety of timers you can choose from a 2 hour timer to a fully automatic LCD electronic timer.

    Note: Early morning watering and covering your system with mulch is recommended to reduce evaporation.

    It is a good idea to clean out and check your system as drippers can become blocked. At least once a year, unseal the end of the system and flush it through.

    A range of drip tubes and weeping hoses are available at Bunnings.

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint Test.
