Portland Water Bureau owns the water main in the street and the section up to the meter at your property line — everything from the meter to your house belongs to you. On a typical Portland lot that's 50–75 feet of buried supply line, and on older inner-east-side properties (Irvington, Sellwood, Eastmoreland, Ladd's Addition) it's almost always still the original galvanized steel.
Galvanized service lines fail one fitting at a time, sometimes years before the rest of the run gives. We see plenty of older lines that have one bad joint at the meter pit or a single failed coupling mid-run, and otherwise sound pipe on either side. A spot repair on a line like that can buy you anywhere from another year to another decade — and we'd rather make that fix than quote a full replacement when a small in-place repair solves the actual leak.
When the line is past saving — multiple failure points, a leak we can't isolate, or end-of-life across the run — we'll say so plainly, and we have a separate estimate for that. Either way, you see what we found and you decide.
