Commercial kitchens in Florida face plumbing requirements that go well beyond residential standards. Whether you are opening a new restaurant in Melbourne, renovating an existing commercial kitchen in Palm Bay, or adding a food prep area to a business, understanding these requirements is essential for passing inspections and avoiding costly violations.
At Inlet Mechanical, we handle commercial kitchen plumbing installations and compliance work throughout Brevard County. Here is what business owners need to know.
Commercial Kitchen Plumbing Florida: Grease Trap and Interceptor Requirements
Every commercial kitchen in Florida that produces grease-laden wastewater must have a grease trap or grease interceptor. This is not optional — the Florida Building Code and local health department regulations require grease management to protect the municipal sewer system.
Interior grease traps are smaller units installed under or near the kitchen sink. They are suitable for low-volume operations like coffee shops, delis, and small cafes. Exterior grease interceptors are large underground tanks required for full-service restaurants and high-volume food preparation facilities.
Brevard County requires regular grease trap maintenance and documentation. Most jurisdictions mandate pumping every 30-90 days depending on the size and volume of the operation. Failure to maintain grease traps can result in fines, and a grease blockage in the sewer main can result in liability for cleanup costs.
Backflow Prevention
Commercial kitchens must have backflow prevention devices on their water supply connections. These devices prevent contaminated water from flowing backward into the potable water supply — a serious health hazard in food preparation environments.
The Florida Plumbing Code requires specific types of backflow preventers depending on the hazard level. Commercial dishwashers, chemical dispensing systems, and any connections to non-potable water sources all require appropriate backflow protection.
Backflow preventers must be tested annually by a certified backflow tester, and test reports must be submitted to the local water utility. Brevard County actively enforces this requirement, and non-compliant businesses risk having their water service interrupted.

Frequently Asked Questions
Do commercial commercial systems require different maintenance than residential?
Yes, commercial systems are larger, more complex, and subject to stricter building codes and inspection requirements. They often run longer hours and serve more occupants, requiring more frequent maintenance. Florida commercial properties must also comply with ADA requirements, backflow prevention regulations, and occupancy-specific fixture counts.
How can I minimize business downtime during commercial kitchen plumbing florida?
Scheduling work during off-hours or slow periods reduces disruption. A licensed contractor can often phase the work to keep portions of the building operational. Preventive maintenance contracts are the best strategy — catching issues early prevents the unplanned downtime that comes with emergency failures.

Drain and Vent Requirements
Commercial kitchen drains must be sized to handle the high volume of wastewater produced during peak service hours. The Florida Building Code specifies minimum drain sizes based on the number and type of fixtures — a three-compartment sink, for example, requires a larger drain than a residential kitchen sink.
Floor drains are required in commercial kitchens for sanitation and safety. They must be properly trapped and vented to prevent sewer gas from entering the kitchen. Floor drain grates must be removable for cleaning, and the drains themselves require regular maintenance to prevent buildup.
Proper venting ensures drains flow freely and prevents vacuum locks that can cause slow drainage. Commercial kitchen vent systems are typically more complex than residential systems due to the number of fixtures and the volume of water flowing through them simultaneously.
Hot water requirements for commercial kitchens exceed residential standards. Dishwashers must receive water at 140-160 degrees Fahrenheit, and final rinse temperatures must reach 180 degrees for proper sanitization. This typically requires a commercial-grade water heater and a booster heater for the dishwasher.
If you are planning a commercial kitchen project in Brevard County, start with a plumbing consultation before construction begins. Retrofitting plumbing to meet code after the fact is significantly more expensive than designing it correctly from the start.
