About LeadPipesCheck
Why this exists
People search "does my house have a lead pipe" after a letter from the utility, a pregnancy, a house they are about to buy, or a news story about their city. Most answers they find are either selling a filter or claiming to know what is under a lawn they have never seen. No public database can see your service line. What is public is how much lead your water utility measured in the homes it sampled - homes chosen because they are the likeliest to have lead plumbing. LeadPipesCheck puts that record in front of you for 48,467 community water systems, then shows the two-minute check that answers the question for your own pipe.
Where the numbers come from
Every system page reports EPA's Safe Drinking Water Information System (SDWIS): the 90th-percentile lead result for each Lead and Copper Rule monitoring period a utility has filed. 44,481 systems have at least one result; 3,986 have none on file and their pages say so instead of inventing one. How each number turns into a Test, Filter or check-your-line recommendation is in how to read a lead result.
What this site will not tell you
It will not tell you whether your house has a lead service line. That is in your utility's service line inventory, which every system had to publish by October 2024, or visible at the pipe where it enters your house. Every page says so, because a utility-wide result being low does not mean any one pipe is not lead.
Who runs this
LeadPipesCheck is an independently run site. It is not affiliated with EPA, any water utility, or any filter, testing or plumbing company. If a page ever carries a sponsored link, that is disclosed on the page itself and in the privacy policy.
Written by
Each system page is generated by AI software from the cited EPA data - no journalist or editor writes or reviews a page before it publishes. The lead results come from the utilities' own filings with EPA and the states, not from AI; the AI only assembles the sentences around them.
