Claim 13:
14. A leak detection system for determining upstream leaks in a water distribution system, comprising:
one or more processors; and
one or more memories with code for:
measuring, using a first pressure sensor, a first pressure signal within a first plumbing system in a first building at a first location, wherein the first pressure sensor is within a first water device;
reporting a first pressure over time away from the first location;
measuring, using a second pressure sensor, a second pressure signal within a second plumbing system in a second building at a second location, wherein the second pressure sensor is within a second water device;
reporting a second pressure over time away from the second location, wherein the first plumbing system taps off the water distribution system away from where the second plumbing system taps off the water distribution system;
receiving the first pressure and the second pressure over time remote to one or both of the first water device and the second water device;
analyzing the first pressure and the second pressure over time, comprising algorithmically identifying a leak in the water distribution system outside of the first building and the second building;
approximating a location of the leak using a map and based at least in part on causing one or more operational adjustments of the first water device, the second water device, and/or a third water device to cause one or more changes to the water distribution system;
determining a temporal difference between a first pressure drop in the first pressure signal and a second pressure drop in the second pressure signal, and use the temporal difference to determine an estimated location of water movement causing the first pressure drop and the second pressure drop; and
when the estimated location is outside a plumbing system being analyzed, filtering out a corresponding pressure drop.
