Our Medical Gas installation Process

Every medical gas installation is completed with careful planning, precision and quality workmanship.

1. Consultation & Planning 
We review your project requirements and develop an installation plan that meets your facility's needs.

2. Medical Gas Piping Installation 
Our certified medical gas plumbers install the piping system and components in accordance with state regulations and industry standards.

3. Pressure Testing 
Before the system is placed into service, we perform pressure testing to verify the integrity of the piping and identify any potential issues.

4. Independent Third-Party Testing & Verification 
An independent third-party verifier conducts the required inspections and testing to confirm the system meets all applicable codes and performance requirements.

5. System Certification & Project Completion 
Once the system passes verification, it is certified for use and the project is completed.

After Installation: Once a medical gas system has successfully passed third-party testing and certification, it remains sealed to preserve gas purity and prevent contamination. The system is only opened again if repairs, renovations or future modifications are required.

Why Certification Matters

Patient Safety
Proper installation is critical to maintaining the purity of medical gases and preventing contamination within the system. Certified medical gas plumbers follow proven procedures that help ensure oxygen, medical air, vacuum and other systems operate reliably when healthcare providers need them most.

Code Compliance
Medical gas work is subject to state and industry requirements, like NFPA 99 compliance. Our certified medical gas plumbers use approved installation methods and follow applicable codes to help ensure every project is completed correctly and passes required inspections and third-party verification.
