In Texas, the water utility holds the property owner — not the tenant, not the plumber — legally responsible for annual backflow testing on every assembly on the property. Miss the deadline and the utility can shut off water to the entire building. This guide is the owner-side playbook: what you're on the hook for, how to build a compliance calendar, and how to work with testers so nothing falls through.
Your Compliance Obligations Under Texas Law
- Annual test on every backflow assembly, performed by a TCEQ-licensed BPAT.
- TCEQ-20700 (or city-specific equivalent) submitted to the water purveyor within 10 business days of the test.
- Failed assemblies retested within 30 days — extensions require utility approval.
- Records kept for at least 3 years and made available on TCEQ or utility request.
The 5-Step Annual Cycle
- Inventory: List every assembly by serial #, size, type (RPZ/DCVA/PVB), hazard classification, and last test date.
- Schedule: Book testing 30–45 days before the annual due date. Don't wait for the city notice — it arrives late.
- Verify submission: Confirm the utility received the passing report. "Tester emailed it" is not proof.
- Repairs: If any assembly fails, book the repair within the same visit if possible; retest within 30 days.
- Archive: Save signed reports in a shared drive accessible to your property manager and legal.
Portfolio-Level Budgeting for Texas Assets
| Property Type | Typical Assemblies | Annual Test Budget | Repair Reserve |
|---|---|---|---|
| Retail strip center | 1–3 | $150–$450 | $500 |
| Class B office | 3–8 | $450–$1,500 | $1,200 |
| Mid-rise multifamily | 4–12 | $600–$2,200 | $1,800 |
| Hospital / medical | 15–60 | $3,000–$12,000 | $5,000 |
| Industrial / manufacturing | 10–40 | $2,000–$8,000 | $4,000 |
Where Compliance Actually Breaks Down
- Ownership changes. New owner doesn't get the utility's notice sent to the old owner. Update the utility contact within 30 days of closing.
- Tenant improvements install new assemblies. That new RPZ on the coffee-shop TI now needs annual testing — but no one added it to the property inventory.
- Testers file the report to the wrong PWSID. In multi-jurisdiction metros like DFW, verify your PWSID once and put it in the property record.
- Failed test with no retest scheduled. Most shutoff notices come from missed retest windows, not missed annuals.
Working With Your Tester
Choose a Texas-licensed BPAT (verify on TCEQ's roster) who covers all the jurisdictions where you hold property. For DFW and Houston-area portfolios, one tester with multi-city coverage is dramatically simpler than juggling three testers. Ask for:
- Copy of current BPAT license and gauge calibration certificate
- General liability insurance certificate
- Digital delivery of the signed TCEQ-20700 to your compliance email
- Utility submission confirmation for every property

Frequently Asked Questions
Can a lease shift compliance to the tenant?
Cost can be passed through, but legal responsibility to the utility stays with the property owner. Verify completion regardless of lease language.
What if I bought the property mid-cycle?
Ask escrow for the last test report. If you can't find one, book a fresh test immediately — the utility clock doesn't restart on ownership change.
Does the utility notify me before shutoff?
Usually one written notice, then shutoff. Respond within 5 business days of any utility letter.
