Hopefully you are all set by now. Unclear from your post if there is an issue with system or system configured wrong...
If it were me, I would:
- find the manual that tells me how to setup and test the sprinkelrs... OR
- I would give your builder a call and ask for help. Our builder was always very nice. I suspect they will send out someone to give you a sprinkler orientation OR
- find a neighbor, if your neighborhood is like mine, folks will be more than happy to help
Let me know if none of that works....
