We came for a leak. The leak was a mainline break just outside of the manifold box. The cause (that we could see) was the box settling on the mainline. The mainline and lateral lines were drilled through the sides of the manifold box. We cut away the box to prevent this same issue again in future. We made the mainline repair, and properly installed a new manifold box. We were able to check the front system afterwards. We made an extensive drip repair (lateral lines are poly pipe), and changed a MP nozzle that had failed on zone 3. We changed a wry clogged nozzle on zone 2. We checked our work and spoke with the customer.
