Testing & Repair
By Property
We do same-day or next-day irrigation and sprinkler system backflow testing for HOAs, apartment communities and commercial sites across Fort Worth and DFW. The building keeps its water while we test, most failures are fixed before we leave, and your water utility has the passing report the day we test.

Texas requires a backflow assembly on every lawn sprinkler system tied to city water. On a commercial property, that assembly is tested every year, and again after it’s installed, repaired or moved. It keeps the chemicals and fertilizer in the soil from being pulled back into the drinking water when pressure in the main drops.
Only a TCEQ-licensed tester can run and sign the test, and that signed report is what your water utility’s notice is asking for. A landscaping crew can keep the sprinklers running, but it can’t sign the report unless someone on it holds the license.
Already past due? We’ll be there the same day or the next.
Same day or next day.
Book today, and a tester is at the property the same day or the next. Pick an open time on the booking page without waiting for a callback, or call and we’ll fit the site in. Sites that can’t have a crew on the grounds during business hours get early or weekend windows.
You don’t need to know which assembly the site has. Commercial sites are on file from city records, so we know exactly what to do and where it’s located. The truck brings the test gauge and rebuild kits, and the tester covers the PVB, RPZ or double check on the irrigation along with every other assembly at the address, in one trip.

About 20 minutes per assembly
The tester checks the sprinkler backflow preventer for freeze cracks and leaks, closes the irrigation line's shutoff valves and connects a differential pressure gauge to the test cocks. Then the gauge shows whether each check holds and whether the air inlet or relief valve opens when it should. Each assembly takes about 20 minutes.
Nobody has to stand by if we can reach the assembly; a locked cage or vault lid needs someone to open it. We check in with the manager when we arrive, and you know pass or fail before the truck leaves.
The building keeps its water. We shut off only the irrigation line, for about 20 minutes per assembly, so tenants keep their water.
Every assembly, one visit. Along with the irrigation assembly, we test the domestic line and fire line assemblies at the address on the same trip. More on backflow testing in Fort Worth.
Most failures fixed before we leave. Rebuild kits ride on every truck, and if a part has to be fetched, the retest is on us.
Filed the day we test. The passing report goes to your water utility the same day, and a copy lands in your inbox.
We remind you before the city does. Every assembly we test goes into our records with its due date, and next year’s reminder comes from us first.
One account for every property. The company is invoiced, we send a certificate of insurance on request, and every site and assembly sits in one place. Email the property list to team@abstexas.com and we’ll schedule them together.

Most failed irrigation backflows are fixed before we leave. The usual causes are a worn or hardened check disc, a weak check spring, a check that won't seat, or grit caught in a check or the relief valve. The tester pulls the bonnet, puts in new parts from the rebuild kit and runs the test again.
If a part isn't on the truck, we get it the same day, and you don't pay for the retest.
We rebuild before we replace. A cracked body or an old, corroded assembly gets a new one, and we install it ourselves. More on backflow repair.
Already failed a test? Call and we’ll rebuild it and file the passing report.
Once the assembly passes, the report goes to your water utility that day.
A copy lands in your inbox, and we keep one on file, so if the utility ever says a report is missing, those copies settle it. Our testers are on file with every utility we report to. In Fort Worth, that means filing through the city’s online portal, and we handle it for you.
If you manage more than one property, send us the list and we’ll schedule every site together. A large site can get dozens of assemblies tested in one visit, and every property and assembly shows up in one account with its due date. See commercial and property manager testing.
Luke Garner and Aiden Bristow run our tests, and both hold the TCEQ Backflow Prevention Assembly Tester license. We’re family owned, with more than 20 years in the trade and more than 10,000 backflow tests completed across the Metroplex. Customers rate us 4.9 stars on Google.

Yes. On a commercial property the irrigation assembly is tested every year, like the building’s other assemblies, and again after any repair. We run the test, your water utility gets the passing report that afternoon, and our reminder reaches you before the next one comes due.
Yes. The backflow preventer on a lawn or landscape sprinkler system is the irrigation assembly, usually a pressure vacuum breaker (PVB), sometimes a double check or an RPZ. It gets the same yearly test, and your water utility gets the same passing report. Fire sprinkler systems are separate: their backflow assembly sits on the fire line, and we test it on the same trip.
No. An irrigation test closes the shutoff valves on the line that feeds the sprinklers. The building keeps water for the whole test, about 20 minutes per assembly. Only a test on the domestic line cuts water to the building, and that line has its own assembly.
Only to open something. If the assembly sits in a locked cage or vault, have someone open it or leave access; otherwise we can work without anyone standing by. We check in with the manager when we arrive and tell you pass or fail before we leave.
Only if the person running it holds the TCEQ Backflow Prevention Assembly Tester license, because the utility accepts only a licensed tester’s signed report. Luke Garner and Aiden Bristow hold that license and run every test we do, and we file the report the same day.
An RPZ. Texas rules require one before fertilizer or chemicals go through a system on city water. The same goes for tying a well or a pond pump into it. In Fort Worth that RPZ goes at the meter. If the site doesn’t have one, we install it; if it does, we test it on the same visit as everything else at the site.
A little, depending on where it sits. Freezes aren’t a big worry here, but an assembly above ground in an open spot does best under an insulated cover, and a line that sits idle all winter can be drained. In Fort Worth, an RPZ in an insulated box needs a drain to open ground. After a rare hard freeze like February 2021, have it checked before the irrigation runs again, because a cracked body has to be replaced.
Yes. Send us the list of properties and we’ll schedule them together. Each report is filed the day that site is tested, and every assembly shows up in one account with its due date, so next year’s round is already lined up.
