DBPR compliance checker, tank sizing, hot water requirements & free quotes
🍳 Mobile Food Unit System Planner
Florida has one of the largest food truck markets in the USA — over 20,000 licensed mobile food units. All must comply with FL DBPR (Dept. of Business & Professional Regulation) plumbing requirements. Use this planner to design a compliant system.
🔑 FL DBPR Core Plumbing Requirements — At a Glance
3-compartment sinkRequired for all cooking MFUs
Separate handwash sinkAlways required — dedicated only
Hot water at handwashMin 100°F, max 120°F
Hot water at 3-compartmentMin 110°F for wash
Fresh water tank minimumPer use calculation (typically 20–50 gal)
Gray water tankMust be 15% larger than fresh tank
Potable water linesFood-grade materials only
Water heaterTankless or tank — must maintain temp
Commissary affiliationRequired by FL for all MFUs
⚠️ Commissary Requirement — Often Missed
Every FL mobile food unit must be affiliated with a licensed commissary where it prepares food, stores supplies, and dumps gray water. The commissary must have a licensed kitchen and proper plumbing. Your truck's plumbing system must be designed to work with your commissary's hookup points. Failure to maintain commissary affiliation = immediate permit revocation.
✅ FL DBPR Plumbing Compliance Checker
Walk through the required plumbing elements for your FL mobile food unit. A DBPR inspector will check all of these during your plan review and inspection.
✅
3-Compartment Sink (Wash / Rinse / Sanitize)Each compartment large enough to submerge largest utensil. Drain boards on both sides. Food-grade plumbing. Connected to gray water tank or drain.
✅
Dedicated Handwash SinkSeparate from 3-comp sink — cannot be shared for any other purpose. Must have hot (100–120°F) and cold running water, soap dispenser, paper towels. DBPR inspectors check this strictly.
✅
Hot Water Heater — Continuous SupplyMust maintain minimum 100°F at handwash, 110°F at 3-comp wash sink. Tankless water heaters are popular in food trucks for space savings — must be sized for simultaneous use at both sinks. Propane or electric.
✅
Fresh Water Tank — Food Grade, NSF-ApprovedTank must be NSF-61 certified food-grade material. Sized for full day of operation. Minimum 15 gallons for beverage-only units; 20–50+ gallons for full cooking. Must have fill port and vent.
✅
Gray Water Tank — Minimum 15% Larger Than FreshFL DBPR requires gray water tank to be at least 15% larger than fresh water tank to account for wash water expansion. Must be sealed, no leaks, must not be connected to any exterior drain while in transit.
⚠️
Food-Grade Water Supply LinesAll lines carrying potable water must be NSF-61 certified (typically food-grade PEX, CPVC, or stainless braided). No standard PVC or galvanized for potable water in an MFU. Lines must be insulated to prevent freezing (less of a concern in South FL).
⚠️
Water Pressure — 20 PSI Minimum at All FixturesFL food code requires minimum 20 PSI at all plumbing fixtures. Onboard tanks must use a pump (typically 12V RV pump, 3–5 GPM). Pump pressure switch set to maintain pressure at fixtures during peak use (both sinks running).
⚠️
Backflow Prevention at City Water HookupIf unit has a city water hookup port, a backflow preventer (vacuum breaker or check valve) is required at the inlet. Prevents contamination of public water supply when truck disconnects under pressure.
❌
All Drains Routed to Gray Water Tank — No Open DischargeZero discharge to ground, pavement, or storm drains while operating. All sink drains must be plumbed to the gray water holding tank. Discharge to ground is a DBPR violation and can result in permit revocation.
❌
Tank Labeling — Required by FL CodeFresh water tank must be labeled "POTABLE WATER." Gray water tank must be labeled "WASTEWATER — NON-POTABLE." Fill ports must be clearly identified and color-coded (blue = potable, black/gray = waste).

What affects the price?
Pricing depends on the size and layout of your home, the pipe materials and fixtures you choose, your Florida region and local labor rates, and permit fees. Work that is more complex or harder to access generally costs more.
Can I DIY this, or should I hire a licensed plumber?
In Florida, minor maintenance may be DIY, but anything beyond that generally calls for a licensed plumber, and many jobs require a permit and inspection. When a permit, gas work, or your main water or drain lines are involved, hire a Florida-licensed plumber.
Does homeowners insurance cover it?
It depends on the cause and your specific policy. Sudden, accidental damage is more often covered than gradual wear-and-tear or maintenance - confirm the details with your insurer.
How long does it take?
Timelines depend on scope - many routine jobs take a few hours to a day, while larger projects run longer. Your licensed plumber can confirm after assessing your home.
