Where the water comes in: meter box or well house
On city water in Olympia, Lacey or Tumwater, water arrives through a meter in a box near the street; on a rural lot it comes from a well, often with a small well house over the pump and pressure tank. This first stop covers both sides: whose pipe is whose, testing a well, and finding leaks.

On city water, the meter and the pipe on the street side belong to the city, and only city staff turn the valve in the meter box; your own valve sits on the house side. Start with who owns which pipe and the meter leak check. On a well, the water is yours to test: Washington's Department of Health suggests coliform and nitrate tests every year, explained on the well testing page, and a shared well serving several houses may be a Group B system with county rules of its own.
