Both Contractors and DIYs alike normally use 25mm black Poly pressure pipe (which has a bore size of approx 20mm) from the water connection point to the on/off manual or automatic control valves, then 19mm black “low density” poly pipe from the valves out to the sprinklers. Pipe with a bore size of approx 25mm is the next size up, for those people with higher flowrates (which means you may be able to run more sprinklers at once) and/or longer pipe runs where you would lose a lot of pressure in smaller pipe.

There are three main options of connecting to your water supply:

1. Connecting straight to the tap with pressure pipe, low density pipe, manual multi-outlet distributors, manual timers or battery-operated automatic timers.
2. Connecting behind the tap so that your tap can still be used for other things. You will then need to put on a 2nd tap or an ‘approved’ shut-off valve of some description.
3. Connecting into your house mainline, somewhere between the water meter and the front of the house. In Brisbane, this mainline is usually 20mm or 25mm Poly pipe, Copper or Galvanised Iron.
   

Additionally, there are a number of ways of controlling the on/off operation of your different sprinkler zones:

1. Manual twin tap and multi-outlet distributors connected straight to your garden tap. The final shut-off operation should be controlled by the garden tap as these valves are not pressure rated.
2. Manual in-line valves. The final shut-off operation should be controlled by the garden tap as these valves are not pressure rated.
3. Manual pressure-rated ball valves.
4. Battery-operated single & multi-station automatic controllers and valves. In most cases these are of a lesser quality than the 24vac controllers.
5. 24vac Automatic controllers and valves. The controller plugs into your 240volt power point then has a transformer reducing the power supply to a safe 24vac.
   

• Water supply (Water connection point to the control valves).
• Manual or Automatic sprinkler zone control, whichever is applicable.
• The sprinkler zone which includes sprinklers, sprinkler pipe and fittings.

• Do not exceed 80% of your available Flowrate from your tap. The leftover pressure will go toward propelling the water outwards.
• Do not exceed the Flowrate shown for the pipe size you select. Total sprinkler flowrate will be calculated by adding together all the individual sprinkler flowrates within a zone.
• Do a Head to Head sprinkler layout along a lateral run. This means sprinklers with a 5mt radius should be spaced no further than 5mt apart creating at least 100% overlap.
• Group your sprinklers within a zone according to their style of watering and application e.g. keep your lawns and gardens separate. The five main sprinkler groups are:
  
  
  • Garden micro sprinklers.
  • Static (non-rotating) lawn sprinklers.
  • Mid-range single jet rotating lawn sprinklers.
  • Mid-range multi-jet rotating lawn sprinklers.
  • Longer range single jet rotating lawn sprinklers.
