My Hunter sprinkler heads don't pop up high enought to get a good spray over the grass. Is there a way to add an extention or do I have to dig them up and raise the entire head?
Either way you have to dig up the head to raise it or to add an extention. They make a pvc riser extension 3/4" MPT X 3/4" FPT that work well for rotors. 1/2" MPT X 1/2" FPT work well for sprays. Verify the size first.
