Is the housing in 85255 all one vintage?
Close to it: about 43 percent of the homes in 85255 went up in the 1990s. That is a tight concentration for a Valley ZIP code.
A block of housing that size from the 1990s means the pipe repeats too. Repetition is the one thing that makes a leak predictable.

Less likely along the run, not less likely overall. The median in 85255 is 1999; in 85254 in Phoenix, 8 miles off, it is 1986. Young systems fail at their connections instead, and a fitting loses water just as fast.

Why would a leak in 85255 leave no mark indoors?
Further than most people expect. 85255 is about 88 square miles of ground. So the private line from the meter to the house is often a long buried run.
Past the meter it is yours, however far it goes. Across 88 square miles a loss can be entirely invisible. Sometimes a patch of ground stays greener than the rest, and sometimes nothing.
So we start with the route rather than the sound. Knowing the route turns a yard into a line. See underground leak detection.
Is all of 85255 inside a city?

The damp is in my unit but my neighbour thinks it is their pipe. How is that settled in 85255?
Under pressure, one line at a time, before ownership comes into it. About 32 percent of 85255 is attached or multi-unit. Where it appears says nothing reliable about whose pipe lost it.
Will you dig or open a floor in 85255 to find out where the leak is?
