San Antonio Backflow Testing & Certification
Texas requires your irrigation backflow preventer to be tested every year by a licensed tester. AAIS is TCEQ-certified — we test, certify, and file the paperwork with SAWS or your water provider, so you stay compliant and your drinking water stays protected.
State-licensed & certified
TCEQ-Licensed Backflow Testers
In Texas, only a licensed Backflow Prevention Assembly Tester (BPAT) can legally test or repair your backflow assembly. AAIS is certified and licensed by the TCEQ — BPAT# BP0018846 — so your test is valid, accepted by SAWS and area water providers, and done right the first time.
What Backflow Is — and Why Testing Is Required
Backflow is when water reverses direction and flows backward into your clean water lines — pulling in whatever’s in your irrigation system: lawn chemicals, fertilizer, pesticides, and bacteria from the soil.
It usually happens during a sudden pressure drop — a water-main break, a fire hydrant being flushed, or heavy demand nearby. Your backflow preventer is the one device standing between that contaminated water and the water your family drinks.
That’s why the State of Texas (TCEQ) and the City of San Antonio (SAWS) require your assembly to be tested every year by a licensed tester. AAIS handles the whole thing — test, certification, and filing — so you never have to think about it.
Why Annual Backflow Testing Is Required
It isn’t just a good idea — it’s the law in San Antonio and across Texas.

On-Site Testing
A certified tester checks your assembly for leaks, pressure loss, and backflow risk — usually done in under an hour.
Pass — Certified & Filed
If it passes, we file the certification report with SAWS or your city and hand you a copy for your records.
Fail — Clean & Retest
If it fails, we disassemble, clean, and retest at no extra charge — which often fixes the problem on the spot.
Repair or Replace (Only If Needed)
If a repair or replacement is needed, we explain why and quote it up front. No work is done without your approval.

A Homegrown Business, Not Just Another Contractor
Chris Mayberry started All American Irrigation Systems in 2003, at just 18 years old, passing out flyers door-to-door in the neighborhood he grew up in. Over 20 years later, AAIS is one of the most trusted irrigation companies in the San Antonio area — relied on by HOA boards, national brands, and regional property groups, with a team that still shows up with the same pride and professionalism on every job.
