Utility: City of Fort Worth Water Backflow Program
Last verified: 2026-04-04
Due basis: All backflow protection assemblies must be tested on installation, repair, or relocation and annually after that. Commercial-class irrigation backflows are also tested annually.
Highlights
- Fire protection sprinkler backflows are still in the annual testing program.
- Testing or repair must be done by a BPAT who is a full-time employee of a fire protection sprinkler company licensed with the State Fire Marshal's Office.
- Inspection paperwork must be complete and available onsite.
Workflow
Workflow
- Confirm the fire line assembly is tied to the proper plumbing or fire permit path.
- Use a BPAT employed by a licensed fire protection sprinkler company.
- Keep the test report onsite and in VEPO so the City inspection does not fail for paperwork reasons.
Residential
- Homeowners can install an irrigation system at their own residence, but testing and inspection still route through Fort Worth's registered-BPAT and permit workflow.
- Residential users usually hit the City process when an irrigation assembly is installed, altered, repaired, or needs inspection closeout.
Commercial and managed properties
- Commercial properties carry the heaviest procedural load because annual testing, VEPO submission, and onsite inspection records all matter together.
- Incomplete paperwork can fail inspection even when the field work was already performed.
Tester routing
Use the governing authority's official tester list first, then only treat any sponsor placement as secondary routing.
