During the follow up visit, the issue that the client was concerned about in zone one was unrelated to the new spray head that was installed in the backyard. The flex line on two barbed elbows that were threaded into lateral PVC lines had come loose underground and were leaking on the right hand side of the house in zone one. The appropriate repairs were made for the two leaks, and an overall system check was completed. No other major issues were found throughout the property.
