SUCCESS...The suspected System 1 water leak has been isolated!
Our water volunteers, along with the meter can project investment (hardware, software, training, etc.), quickly located the leak area. The water to that property has been shut off and the homeowner notified.
The LevelCon tank monitoring system is reporting 19 inches after being near empty overnight!
Thanks for your patience and responses from many of you about suspect areas.
