Potosi ground conditions make confirmation worth the extra care.
In Potosi, clay-rich soil changes through the seasons. A long hot, dry spell draws moisture from the ground, so soil shifts or pulls away around buried pipe. After substantial rain, that soil takes on water and moves back. Those changes work against buried lines and connections, especially where the pipe has little room to move with the ground.
The same conditions can make an outdoor wet area difficult to read. Rainwater can leave soil wet without there being a pressurized plumbing leak, while a leaking supply line can keep ground saturated after the weather has changed. We look for evidence that separates those possibilities before a slab is opened or ground is excavated.
A house in Potosi can also have a longer buried run between the water connection and the building. That leaves more pipe outside the walls to assess. An exterior leak can waste water and leave persistent saturation in the ground without producing the wall or ceiling staining often associated with an indoor leak.
