How to install fixed pipe irrigation
Dig a trench around the perimeter
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.
Cut PVC pipes to length
Insert T pieces at sprinkler positions
Install the solenoid valve at the water source
Prime and glue the joins
Attach the sprinklers
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.
Backfill the trench
Now, using your spade, backfill the trench with soil to cover up the whole watering system.
Check the system is working properly
