What Is Commercial Plumbing?

Commercial plumbing is the installation, maintenance, and repair of plumbing systems in businesses and larger properties — restaurants, offices, retail, and multifamily buildings. It differs from residential work in scale and code: bigger pipe networks, higher water demand, backflow-prevention requirements, grease management, and stricter Florida code and inspection rules.

Why it needs a commercial-experienced plumber: a business plumbing failure isn't just an inconvenience — it can shut down service, trigger a health-code issue, or damage tenant spaces. The work has to be done right, fast, and to code, which is exactly what we do.

Repairs & Systems

We serve restaurants, retail and office buildings, medical and dental offices, and apartment, condo, and multifamily complexes — plus new construction and tenant build-outs. Need home service instead? See our residential plumbing.

Backflow Testing & Certification

Florida requires commercial properties with a backflow preventer to have it tested and certified every year, and Flow Pros is backflow certified to perform that testing. A backflow preventer stops contaminated water — from irrigation, boilers, or other cross-connections — from flowing back into the clean drinking-water supply.

We test, service, and certify your backflow assembly and file the paperwork so you stay compliant with state and local regulations. If a device fails, we repair or replace it and re-test. You can verify our license (FL #CFC1433820) with the state anytime, and your local water utility sets the annual filing deadline.

Grease Traps, Gas Lines & Underground Locating

Commercial kitchens and larger properties have needs a home never will, and these are the ones businesses call us for most.

  • Grease trap maintenance — keeping St. Pete restaurant kitchens compliant and clog-free, backed by hydro jetting for grease-packed lines.
  • Gas leak detection & repair — licensed work on gas lines serving kitchens, water heaters, and equipment.
  • Underground line locating — pinpointing water, sewer, and gas lines before any excavation to avoid costly strikes.
  • Commercial water heaters — gas, electric, tank, and tankless systems for high-demand properties.

Commercial Plumbing FAQs

What's the difference between commercial and residential plumbing?
Commercial plumbing handles larger, higher-demand systems in businesses and multi-tenant buildings, with bigger pipe networks and stricter code, including backflow prevention and grease management. Residential plumbing focuses on single homes. Commercial work also carries higher stakes, since a failure can shut down a business or cause a health-code violation, so it needs a commercial-experienced, licensed plumber.
How often does a commercial backflow preventer need testing?
In Florida, commercial backflow preventers must be tested and certified annually. Flow Pros is backflow certified to test, service, and certify your assembly, and we file the paperwork to keep you compliant. If the device fails, we repair or replace it and re-test. Your local water utility sets the exact annual deadline.
Do you service restaurants and grease traps?
Yes. We maintain grease traps and clear grease-packed kitchen lines for St. Petersburg restaurants, using hydro jetting to scour the lines clean. Regular grease maintenance keeps your kitchen compliant and prevents the backups that shut a restaurant down during service. We can set up a maintenance schedule based on your volume.
Do you handle new construction and tenant build-outs?
Yes. We handle commercial new-construction plumbing and tenant build-outs, from rough-in through fixture installation and final inspection. Whether it's an office suite, retail space, or restaurant, we coordinate with your timeline and do the licensed, permitted work so your build-out passes inspection.
Do you offer 24/7 emergency service for businesses?
Yes. Flow Pros provides 24/7 emergency commercial plumbing across St. Petersburg and Tampa Bay. A burst pipe, sewer backup, or water heater failure can halt your operations, so we prioritize business emergencies and dispatch a licensed plumber any hour. Call 727-265-9639.
