Tulsa Backflow Testing

Protect What Matters Most—Keep Contaminants Out

Once contamination enters the line, cleanup isn’t easy—and health risks rise fast. Pressure changes, outdoor tap misuse, and outdated hardware can all allow unsafe water to backtrack into what should be a clean supply. The cost of ignoring it? Unexpected fines, failed inspections, or worse—an undetected exposure risk for anyone using the taps.

Mullin Plumbing provides reliable prevention you don’t have to think twice about. Our certified specialists inspect, install, and test with full code compliance and no guesswork. If you’ve received a notice or just want to be sure your lines are secure, call 918-215-2608 today. It only takes one visit to confirm that your protection is in place—and built to last.

Residential vs Commercial Risk Points Aren’t Created Equal

Backflow issues in residential spaces tend to originate in irrigation lines, hose bibs, or improperly installed water heaters. Without a check assembly in place, contaminants like fertilizer, pool treatment chemicals, or stagnant garden runoff can be pulled into the supply. These conditions often go unnoticed until annual testing—or a boil order—makes the danger obvious. Early prevention through device installation near pressure-sensitive zones is one of the most effective safeguards.

In commercial environments, the stakes multiply. Kitchens, fire suppression systems, industrial boosters, and multi-point restroom setups create complex pressure zones with multiple cross-connections. One faulty valve or worn assembly can compromise more than a single tap—it can expose everyone in the building. At Mullin Plumbing, we account for fixture load, elevation pressure shifts, and usage patterns to map out the best approach. Whether it’s an assisted living facility, a restaurant, or a retail space, we bring clarity and control to every install and inspection.

Certified Testing, Installation & Repairs That Keep You in Compliance

When it comes to protecting clean supply lines, code compliance is only the beginning. Our certified plumbers handle everything required to pass inspections, maintain device reliability, and correct cross-connection hazards at the source. Every job is done cleanly, with full documentation and minimal disruption to your day.

    We install testable, code-approved backflow preventers at irrigation tie-ins, fire lines, commercial kitchens, and water supply entries—tailored to your layout and pressure zone.
  • Annual Compliance Testing and Paperwork Submission
    Our certified testers arrive on time, run detailed diagnostics, and submit signed results to your utility provider or municipal agency—so you never miss a deadline.
  • Quick Turnaround Repairs and Retesting
    Failed inspection? We isolate the issue, replace worn valves or check mechanisms, and retest for immediate clearance.
  • Cross-Connection Point Audits
    We evaluate irrigation, booster pumps, and fire loops to flag backflow potential before it becomes a liability.

Why Backflow Risks Aren’t Just Theoretical

Backflow contamination doesn’t always start with a dramatic event. All it takes is a temporary pressure dip, an open hose left in a pool, or a malfunction in a nearby irrigation line. When those conditions align, water that’s meant to leave your property can reverse direction—and pull pesticides, fertilizers, or waste material into what’s supposed to be clean. You won’t always see it. You won’t always smell it. But the risk is very real.

That’s why so many local codes require annual backflow testing. Cross-connection issues have caused outbreaks in restaurants, apartment buildings, and even small residential neighborhoods. Once the line is compromised, cleanup goes beyond a single property—it affects entire supply chains. At Mullin Plumbing, we catch these vulnerabilities before they put anyone at risk. Every test, replacement, and installation we perform is guided by regional code and decades of practical experience.

Temo and Chris from Mullins Plumbing were fantastic! They came out the same day, communicated clearly, and quickly found the problem. The smell in our house turned out to be from a P-trap that had been installed incorrectly, and they resolved it right away. They also located some ductwork that needed to be reconnected, which was a huge help. Fast, professional, and knowledgeable, highly recommend!
