Commercial floor drain cleaning
Floor drains take everything that hits the floor: grease, food solids, detergent, grit, mop water and whatever came off the last delivery.
In a commercial kitchen the floor drain is arguably working harder than the sinks. Mop water carries dissolved grease that cools and deposits in the trap, food solids wash in from prep and cleaning, and the whole assembly rarely gets more than a rinse. The trap fills, then the branch line, and then you are running a service with water standing on the floor.
Cabling a floor drain bores through the sediment and leaves the rest of it in place, which is why they come back so quickly. Pressure is what actually removes sediment, so these lines get jetted.
Signs it needs service
- Standing water after a wash-down
- Slow drainage during service hours
- Persistent odor near the drain
- Fruit flies or drain flies around the grate
- Backing up when another fixture runs
What we do
- Lift the grate and clear the basket and trap
- Jet the branch line through to the stack
- Check the trap primer where one is fitted
- Flow test under a real wash-down volume
Drain flies mean film, not filth
Drain flies breed in the organic film lining a drain, not in dirt on the floor, which is why mopping harder never fixes them. Removing that film with pressure removes the breeding site, and the flies go with it.

Questions about floor drain cleaning
How often should commercial floor drains be cleaned?
In a high-volume kitchen, quarterly is common. In a warehouse or a low-traffic washroom it may be annually. We camera and assess before recommending an interval rather than putting every client on the same schedule.
Why do my floor drains smell even after cleaning?
Usually a dry trap. Floor drains that get little water evaporate their seal in Florida heat and let sewer gas straight through. Where that keeps happening, a trap primer is the permanent fix rather than remembering to pour water down it.
