Boots is right. The Sure Pop is a horrible sprinkler.
They do sell the 1800 Series at the Home Depot though. That should fix you up.
They only sell the 4 inch pop up.
If you need a different height go to an irrigation supply house such as Ewing or Hydroscape.
They'll be much cheaper there as well.
You could buy them online at

If you need a regulator on your system you'll have to call a guy if you can't do it.
Call a sprinkler guy not a plumber and not your gardener.
