so we have been working on a project that has an existing system. They are redoing the the landscape in the front yard so we are renovating and adding some zones. So yesterday I get a call that the landscapers were planting some screening trees by the road and found a bunch of buried valves. Turns out there was a curb stop and 10 zone manifold that was long since forgotten about. We cut out the valves and capped the main.
