Replaced zone valve 4 that had broken and started leaking from root growth, in addition we redid all the connections watering proofing them in the junction box from the controller to the wiring for the yard. The water meter on the property isn’t working well, with the dial on the meter jumping (while we had a good amount of water running) while it’s supposed to smoothly move. This defect in the meter might be why the leak did not show up on the meter.
