There are two main methods of sprinkler system installation: open trench and pulled pipe. Open trench typically uses PVC pipe and pulled pipe typically uses poly pipe. Other than the pipe and fittings, the main difference in installation will be that the pulled pipe system requires a hole and saddle tee at the location of each sprinkler head.

The steps for installing an automatic sprinkler system using an open trench method are:

1. Start with a good sprinkler system design (try searching "sprinkler system designer" for support options)

2. Make sure that you have all necessary tools, equipment, and permits

3. Have Blue Stakes mark all utilities prior to any digging

4. Install a backflow prevention device according to code

5. Place flags at the location of each sprinkler head

6. Mark and dig all trenches and valve manifold locations

7. Build and install valve manifolds (preassembled valve manifolds can make this easier)

8. Connect mainline pipe from water source connection to valve manifolds

9. Lay lateral line pipe from the valve manifolds to the location of each sprinkler head

10. Install tees and swing assemblies for each sprinkler head and flush lines

11. Connect sprinkler heads to swing assemblies; set head to level with ground

12. Install sprinkler timer/controller and connect sprinkler wire from timer to valve manifolds

13. Install nozzles on sprinkler heads

14. Install valve boxes (as required) and backfill all trenches

15. Run a zone by zone test and adjust nozzle patterns
