Grease Trap Service FAQ
How often should a grease interceptor be cleaned?
Most St. Louis kitchens fall on a monthly or quarterly cycle, but the governing rule is servicing before grease and solids reach 25% of the tank depth. We set frequency from your actual load.
Do you provide documentation for inspections?
Yes. Every service generates a dated ticket and manifest formatted for MSD and health-department review.
Can you service the trap outside business hours?
Yes. Most restaurant service happens before opening or after close so the kitchen never loses a shift.
