The short answer
In Mercer Island, 3% of housing was built before 1940. A bill that climbs with nothing damp indoors points to the private side of the meter, outside the building, where water drains away without ever showing.

Mercer Island is a mostly post-war town: 3% of its housing was built before 1940. A leak on a newer service line is usually a joint or a stone against the pipe, not age.
What this site is
AcousticLeak is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. We carry out no work and no leak location, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. Nothing here is a statement about what your own utility will credit; only your utility can tell you that.Mercer Island in numbers

Mercer Island is in King County, Washington. Its ZIP code is 98040. We route leak detection calls from 98040.
How it is actually found
Acoustic listening on the fittings, then correlation between two points on the line, narrows a leak to within a meter or so before anything is opened. Ground-penetrating and tracer-gas methods follow where listening cannot.
The adjustment is worth asking about
Many utilities will adjust a bill once for a hidden leak that has been repaired, on evidence. The terms are set by your own utility and nobody else can tell you what they are.
