Lead Pipe Lookup: Check Your Address

Enter your ZIP and street address to check whether your home has a confirmed lead, galvanized, or non-lead water service line per utility public records — now covering 62 large US water utilities across 2,800+ ZIP codes nationwide.

How this tool works
We republish lead service line inventory records that water utilities have published under federal and local disclosure rules. You enter your ZIP and street address; we check whether your specific address appears in the source dataset and show the material classification that the utility has on file.
  • Material classification on file (lead / galvanized / non-lead / unknown) for your exact address, when available
  • Statistics for your entire ZIP (how many addresses in your area have each material type)
  • Direct link to the original utility source so you can verify
Currently covering 62 large US water utilities across 2,800+ ZIP codes and 11.3 million addresses nationwide — including New York City, American Water (New Jersey + Pennsylvania), Houston, Miami-Dade, the Washington DC area (WSSC + DC Water), San Diego, Philadelphia, Detroit, Dallas, New Orleans, Omaha, Jersey City, Aquarion (Connecticut), Spokane, and many more. Additional cities are in development.

Coverage: 62 large US water utilities — including New York City, American Water (New Jersey + Pennsylvania), Houston, Miami-Dade, WSSC (DC suburbs), San Diego, Philadelphia, Baltimore, Detroit, Dallas, Fort Worth, Tampa, New Orleans, Omaha, Jersey City, Aquarion (Connecticut), Spokane, Milwaukee, Gwinnett County, Albuquerque, Indianapolis, Columbus, Cincinnati, Denver, Seattle, Washington DC, Pittsburgh, and more — at this time (2,800+ ZIP codes, 11,300,000+ addresses). If you live elsewhere, the federal EPA SDWIS database has utility-level lead service line counts on our main lead page.

Your privacy: Your street address stays in your browser. Only the ZIP code is used to load the dataset — we do not transmit, store, or log your specific address on our servers.

Why a lead pipe lookup matters

Lead exposure through drinking water has no safe level for children — even very low levels can affect IQ, attention, and academic achievement, per the CDC. The federal Lead and Copper Rule Improvements (LCRI), finalized in October 2024, requires every US public water utility to publish an address-level inventory of every service line by November 2027. New York City was an early adopter and has been publishing inventory data since 2019 under NYC Local Law 65.

Knowing whether your home has a lead service line is the first step. If your address is confirmed lead or unknown, common next steps include: requesting a free service line inspection from the utility, installing an NSF/ANSI 53-certified faucet filter, running water for 30 seconds before drinking after extended non-use, and asking about LCRI replacement timelines (utilities must replace 100% of lead service lines within 10 years under the federal mandate).

Frequently Asked Questions

Is my address really public information?

Yes. Water utilities are required by federal law (Lead and Copper Rule Revisions, 2021; Lead and Copper Rule Improvements, 2024) to publish service line inventory data, including each address with its material classification. NYC publishes this data through NYC Open Data under NYC Local Law 65 (2019). ZipCheckup republishes the same public records in a more user-friendly interface.

Can I have my record removed from ZipCheckup?

Yes. We honor opt-out requests within 7 business days. Visit the <a href="/tools/lead-pipe-lookup/opt-out/">opt-out page</a> for instructions. Note: opt-out removes the record from our display; it does not remove it from the original NYC DEP public dataset (only NYC DEP can do that).

What if my address shows 'Unknown'?

An 'Unknown' classification means the utility has not yet field-verified the material on that service line. Under the federal LCRI rule, all unknown service lines must be resolved by November 2027. If your home shows Unknown, you can request a free service line inspection from your water utility, or have a licensed plumber visually inspect where your water line enters your basement.

What if my address shows 'Lead'?

If your address is confirmed lead, your water utility is required to replace the service line at no cost to you as part of the federal mandate (timeline varies by utility — large utilities are required to publish a replacement schedule). You can also take immediate steps: install an NSF/ANSI 53-certified faucet filter (effective against lead), use cold water for drinking and cooking (hot water leaches more lead), run the tap for 30 seconds after extended non-use, and consider blood lead testing for children under 6 through your pediatrician.

Is the data current?

The source data was most recently updated by each utility on the date shown in the source attribution block under your result. Utilities update their public datasets periodically as service line inspections and replacements are completed. ZipCheckup pulls each dataset on a regular cadence to keep our display current.

When will other cities be added?

New York City (NYC DEP), Pittsburgh (PWSA), and Detroit (DWSD) are live. We are actively building integrations for additional utilities and the top 20 US water utilities by population. The federal LCRI rule requires all large utilities to publish inventories by November 2027, so coverage will expand significantly between now and then. Bookmark this page or follow us for updates.

Data Sources & Methodology

Data Sources

Methodology

When you enter a ZIP, we load the per-ZIP chunk of the corresponding utility dataset (typically 100-300 KB). We match your street address first by exact text match, then by street name + street number numeric match. All matching happens in your browser — your street address never leaves your device. The displayed ZIP-level statistics are pre-computed from each source dataset at build time. For utilities that publish separate public-side and private-side materials (e.g., Pittsburgh PWSA), we show both sides and a combined worst-case verdict. For utilities that publish a single federal-classification verdict per record (e.g., Detroit DWSD), we show that classification directly.

(1) Replacements completed after each utility's last source-update date are not yet reflected. (2) Address format differences (e.g., 'Saint' vs 'St', '123' vs '123A') may cause no-match outcomes even when records exist. (3) Multi-family buildings may show a single record for the whole building rather than per unit. (4) Administrative categories (e.g., NYC's 'Non-Applicable', PWSA's 'Abandoned', DWSD's 'Fire Line') are excluded from display. (5) Detroit DWSD publishes ~82% of records as 'Lead Status Unknown' pending physical verification — this is the federal LCRR/LCRI compliance baseline, not a data gap on our end.
