Thanks! I'll take a look for that.
I have a TORO system. One sprinkler head is installed at the intersection of the curb (about 4" high) and where our driveway meets the curb. We're very careful to avoid it when driving into our driveway. Unfortunately, I cannot say the same thing about other people that occasionally use our driveway to turn around and what not. The head is not damaged (yet) but it pops out at a slight angle so I think it's been run over (not while sprinkling of course, while in the ground). I'm trying to find so...
