Where the ZIP information comes from
The directory uses the plumbing offer coverage published in Lead Smart’s public coverage tool. Source rows were updated October 29, 2026 and retrieved October 30, 2026. Coverage can change.
| Measure | Count |
|---|---|
| Named city and postal labels | 15,858 |
| ZIP entries with city/state labels | 25,266 |
| Other entries without location labels | 109 |
| State/district directories | All 50 states and Washington, DC |
What a listing confirms
A listed ZIP appears in the source coverage snapshot. It does not book a visit, locate a technician, guarantee an arrival time, or confirm every street address. Call (888) 665-1813 to confirm the property, work requested, and appointment options.
If a ZIP is absent, the finder says it is not listed. You can call to ask about current options, but this directory does not describe that address as confirmed coverage.
Why names and boundaries differ
The source includes postal localities as well as municipalities. A mailing name, city limit, and utility boundary can describe different areas. Use the exact service ZIP and the supplier printed on the water bill.
109 source entries have no city/state label. The finder preserves that limitation without inventing a location. Inclusion in the feed does not validate a postal code.
What local guides add
The initial guides address specific local questions such as private sewer responsibility, water-line boundaries, utility reporting, or the work included in a prevention project. Each guide links to its official sources and explains their scope.
Read how the guides were prepared, including the use of public sources and AI assistance.
Where no local guide is listed, the state directory still shows the source ZIP entries. There is no separate walk-in office implied by a listing, and no job history, repair price, or household plumbing condition has been inferred from it.
