impact head question
Iam currently using a impact head on a spike attached to the hose like the ones at fred meyers (not and inground one). The coverage is great with just one of them in the middle of my 40 x 40 square lawn. If I want to go inground is it as simple as running one line to one pop-up impact head in the middle of the lawn. Sorry that just seems to simple, there must be a catch. Any advice would be great, thanks.
