I don't know what you consider complex, but it's probably a good 300-400' of lines around the front and back yards with one going under the driveway. Lots of fun when that one went right after we moved in. The one that tripled the water bill was caused by a rock that shifted and ruptured a pvc pipe by the driveway. But the leak was right under a bush and it was low pressure, so the water never made a puddle we could see. It just stayed like a swamp under that bush. The control box was replaced once. I think we paid $900 to have some of the lines replaced and leaks repaired. There are now two more leaking that I'll have to do some digging to track down.
