Casselberry’s public instructions contain a timing conflict. The customer-service page says a repair adjustment request should be made within 45 days after repair. The online form says it must be submitted within 90 days of the bill date with proof. Do not assume the longer period controls.
Use the earliest defensible date
Record the statement date, discovery date, repair date, and submission date. File promptly enough to satisfy both published instructions when possible, and ask the City in writing how it applies them to the account.
For a repaired leak, save pre- and post-repair photographs, invoice or parts receipt, repair description and date, meter readings, affected statements, and normal-use comparison periods. For unexplained high use, the City page gives a separate 30-day route; preserve meter checks, occupancy facts, irrigation records, and the precise question submitted.
Keep collection and review separate
The form describes processing in about 10 business days and says collection continues. Record those as two independent facts. A pending request is not an approved adjustment or a payment hold. Save payment confirmations, City correspondence, the calculation or denial, and the revised account ledger.
If the City resolves the deadline conflict for the account, attach that written answer rather than deleting the earlier pages. A complete file should show what was known, what evidence was submitted, when it was submitted, and how the City decided.
