Backflow Repair & Installation in Phoenix, AZ
A backflow preventer is the brass assembly, usually near the irrigation meter, that stops sprinkler water from flowing back into the drinking water supply. Arizona requires it to be tested every year, and when it fails, someone has to fix it. Pro Turf repairs, rebuilds and replaces irrigation backflow assemblies for HOAs, apartment communities and commercial properties across the Valley. We don't do the annual test; we're the crew that fixes what the test finds.

What Arizona requires
Under Arizona's backflow rule (A.A.C. R18-4-215), backflow assemblies must be tested at least once a year, and again after they're installed, moved or repaired, by a certified tester. Valley cities, including Mesa, Gilbert and Tempe, run backflow programs that send notices when a test is due, and overdue tests can lead to enforcement, up to water shutoff. Two Valley-specific hazards: brass assemblies are a target for theft, and the occasional hard freeze can crack an unprotected one overnight.
Backflow assemblies are part of the irrigation system, so repairs often go hand in hand with commercial irrigation repair. Our grounds maintenance crews can also flag damage or theft they spot on regular visits, before the next test does.

Common questions
Do you do annual backflow testing?
No. Annual tests must be done by a certified tester registered with your water provider, and cities like Mesa and Tempe publish lists of registered testers. We handle what comes after a failed test: repairs, rebuilds and replacements.
My backflow preventer failed its test. What happens now?
The assembly has to be repaired or replaced, then retested by a certified tester, with the passing results sent to your water provider. Most failures come down to worn checks, springs or seals, which a rebuild can often fix without replacing the whole assembly.
Should we rebuild or replace a failed backflow preventer?
Rebuilding usually makes sense for a newer assembly in good shape. Old, corroded, freeze-damaged or discontinued assemblies are usually better replaced. We'll tell you which and why before any work starts.
Our backflow preventer was stolen. What should we do?
Call us and your water provider. Some cities, including Tempe, require a permit and the same type of assembly for a replacement, and every new assembly has to be tested before it goes back into service.
Do commercial irrigation systems need a backflow preventer?
In most cases, yes. Plumbing codes require backflow protection where irrigation connects to drinking water, and Valley water providers require those assemblies to be tested every year.
Can you install backflow assemblies on new projects?
Yes. We install backflow assemblies as part of irrigation installations, turf conversions and landscape renovations, and replace undersized or outdated ones while we're there. Where your city requires a permit, we'll flag it up front.
