Why Does My Commercial Kitchen Drain Smell Bad?
Persistent drain odour from kitchen floor traps is an FSSAI violation and a sign of grease buildup inside your pipes.
A foul smell from your commercial kitchen drain in Bangalore is not just unpleasant — it is a documented FSSAI non-conformance and a direct indicator of grease biofilm coating the inside of your drain pipes. Standard surface mopping and chemical cleaners cannot reach or remove this biofilm layer.
What Causes This?
- 1Grease and fat deposits coating pipe walls and decomposing under bacterial action, producing hydrogen sulphide gas
- 2Dry floor traps — the water seal has evaporated, allowing sewer gas to rise directly into the kitchen
- 3Organic matter (food waste, proteins) trapped in drain grates or the first 1–2 metres of pipe
- 4Biofilm layer lining the pipe walls — invisible to the eye but a continuous source of sulphurous odour
- 5Inadequate ventilation in the drain system causing pressure that pushes sewer gas upward into the workspace
How Serious Is This?
FSSAI classifies persistent drain odour as a Category B non-conformance during kitchen inspections in Bangalore. If the inspector records this, you face a corrective action deadline and potential licence suspension on repeat violations. Beyond compliance, hydrogen sulphide released from decomposing grease is toxic at high concentrations and creates a serious occupational health risk for kitchen staff working in enclosed environments.
How Clethorix Fixes It
CCTV camera inspection of all floor traps, drain channels, and the first 10 metres of pipe to identify the exact source and severity of the biofilm
High-pressure hydro-jetting at up to 3,000 PSI to mechanically scour grease deposits from pipe walls — the only method that fully removes the odour source
Bio-enzymatic treatment applied directly into the drain system — live bacterial cultures continue breaking down residual organic matter for 4–6 weeks after service
Before-and-after camera footage provided with a signed FSSAI-accepted hygiene compliance certificate within 24 hours
Prevention Tips
- Install grease traps on all kitchen outlet lines and schedule professional cleaning every 4–8 weeks depending on kitchen volume
- Pour 2–3 litres of clean water into each floor trap daily to maintain the water seal and block sewer gas entry
- Run a Preventix AMC with monthly bio-enzymatic dosing to prevent grease biofilm from re-establishing between service visits
- Train kitchen staff to scrape food waste off plates before washing to reduce the organic load entering the drain system
