Here is just one of the problems that we have been having. Trying to keep the sod wet at all times until it takes root is a challenge because we don't have as many quick couplers to hand water as we need. We have to mainly rely on our sprinkler system and you can see what happens when a sprinkler gets plugged or the valve doesn't come on for a day. (Note the sprinkler in the center of the brown spot)
