Work out where you want your sprinklers to go, making sure the arc for each one overlaps the area of lawn they're covering. Dig a trench around the perimeter of the lawn and calculate how many sprinklers you will need.
When everything is in place, flush the system to get rid of any dirt. Attach the small risers to each pop up sprinkler unit and screw them into the joins.
Now, using your spade, backfill the trench with soil to cover up the whole watering system.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. 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.
