Usually somewhere they had a heavy truck drive over the curb, etc. For all turf, bermuda and fescue (what we have here) we always use 4" and install them at ground level and properly compact the soil underneath them before tightly packing the soil around them. We have never had any problem with the spray being obstructed by the turf if the turf is kept at a healthy height. We primarily use 12's for beds. very rarely use 6's.
I suspect Large mowers are the culprit on turf areas..guys nowadays are using bigger and bigger equipment despite the size of the lawn...we try and use 6 " as replacments any chance so if they get pushed down, it won't make as big an impact in tall turf....also, when the seal or spring fails, the nozzle might actually be stuck above turf making it easier to see and avoid for the mowers
