Provider-specific review
What the public record says about a leak adjustment
The reviewed Illinois American Water pages do not publish a complete East St. Louis leak-credit formula. A customer with a suspected hidden leak should stop the leak, retain plumber invoices or repair receipts, document the affected meter readings and dates, and contact customer service promptly to ask whether the district tariff permits an adjustment and what application deadline and proof standard apply.
Stop the loss
Shut off the failing fixture or supply and arrange a qualified repair.
Keep proof
Save dated invoices, parts receipts, photographs, and meter readings.
Request review
Submit the request promptly and keep paying any undisputed amount.
