How our tools work

The checker maps your state selection to the usual responsibility split, the state's lead service line page, and utility programs we found. It is a starting point for research, not a substitute for the official utility rule for a specific property.

Start with your state if you only need the common pattern: utility side, homeowner side, curb stop, meter, and where local rules often differ.

Then search your city, county, utility, or ZIP to confirm the office that actually serves your address. If a property line, curb stop, easement, meter setting, or private road is involved, always check the official utility or public works office before arranging repairs.

Nothing you type into a tool is saved on our servers unless the tool says so. Letter builders and checklists run entirely in your browser.
