City of Lewisville Backflow Testing approved testers

This page mirrors cached entries from the governing authority's published tester list. Sponsor-only inventory stays off public pages and inside the private admin workflow.

Official list entries

Authority-first tester table

Use the governing authority list first. Provider profiles and sponsor routing remain secondary to the official approval context.

No local official entries are cached yet

This route is live because the official program path is strong enough, but the file registry does not yet cache individual tester entries for this utility.

Utility workflow

Stay on the official compliance path

The utility page remains canonical. This tester surface should only help the user take the next step after the exact reporting and deadline path is clear.

  1. Confirm the property falls into one of Lewisville's listed hazard categories or has received a City notice.
  2. Use a Texas-licensed tester who is currently registered with the City of Lewisville.
  3. Submit the completed test through BSI Online within ten days of the test date.
  4. Use the tester list carefully, because not every tester is licensed for every assembly type.
