I posted this on the irrigation forum too for their opinion. I have a customer that will be installing a sprinkler system and new sod. I will be doing the sod, and another company will be doing the sprinklers. What would be the easiest installation? Sod first? sprinkler system first? I was considering doing the old sod removal then letting the sprinkler system go in then finishing the sod installation over that. Good idea or no?
