Preventing Drain Clogs in Commercial Kitchen Sinks
Running a commercial kitchen? Then you know every second counts — and drain clogs can bring your operations to a standstill. Recently, our plumbers were called to a restaurant in Oakville where a steel wool scrubber had completely blocked the sink drain, halting kitchen flow during lunch rush.

Common Causes of Commercial Sink Blockages:
- Steel wool pads
- Grease buildup
- Food debris
- Broken drain components
Preventive Tips:
✅ Use drain baskets to catch solids
✅ Avoid flushing steel scrubbers or packaging

Safe biological enzymes can help break down organic buildup without damaging your pipes. - Flush the Sink with Boiling Water
At the end of each shift, flushing the drain with hot water helps remove soap scum and grease residue. - Train Staff on Proper Waste Disposal
