Although the time period between calls has lengthened.

Far from an expert but when you purchase a whatever that part is called that allows the head to rise it comes with a plastic piece installed. You are supposed to run water to that part before installing the head. That way you blow out all the sand etc that might be in the line. You may need to do every head on that line-starting at the farthest head using one of those plastic pieces. "The service," I assume you are paying a flat fee. They do not want to take the time to do it right.
