What's working for you guys? Currently I've been running a 6 man crew. One guy runs the pipepuller/trencher all day, the rest are connecting, backflow, valves, all that good fun stuff. We can get all pipes pulled & connected , valves wired and backflow hooked up in one day. The next morning...install all the heads and connect controller... test her out and good to go. For a typical residential 7 zone or so system. That is if everything goes as planned.... How are you all running your crews?
