Editorial standards

We would rather say less and be right. Every guide and tool on Water Line Rules follows these rules.

Sources we use

We use official and authoritative sources first: utility customer responsibility pages, city and county public works departments, state drinking water agencies, statutes, regulations, court materials, and EPA guidance. When sources conflict, we note the local office that controls service for the address as the one to confirm with.

We cite the primary source whenever one exists: the statute, the agency page, the court rule, or the extension publication. News articles and industry groups are used only for context and are labeled as such. Each guide lists its sources at the bottom with links.

What we will not do

• We do not invent statistics, testimonials, reviews, expert quotes, or credentials.
• We do not present estimates as measurements. Where a number is a rule of thumb or a model, the page says so and explains the math.
• We do not accept payment to include, rank, or recommend anything in our guides.
• We never ask readers to click ads, and ads are always labeled “Advertisement.”

Tools and data

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.

Review and updates

Each guide shows the date it was last reviewed. We re-check sources when we learn a rule has changed and at least once a year. When a change matters to readers, we note it on the page.

Corrections

If you find a mistake, use the contact form and include the page and a source. Confirmed errors are fixed promptly, and substantive corrections are noted on the page with the date.

Limits

Water Line Rules is a general information site, not a law firm, utility, or government office. It is not legal advice and may not reflect every property-specific detail, utility tariff, or local exception. Before you repair, replace, or dispute a line, confirm the rule with the official office that serves your address.
