Grease Trap Installation & Service in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
Grease traps capture fat, oil, and grease before they reach the city sewer. Without one, kitchen drains coat with grease, the city issues fines, and the line eventually clogs. Tornado Plumbing & Drains installs, services, and replaces grease traps for Toronto and GTA restaurants — under-counter units and exterior grease interceptors, sized to volume and code.

Grease trap cost
Pricing depends on size, type (under-counter or exterior interceptor), kitchen layout, and whether the work is new install or replacement. Cleaning and pump-out is priced per visit and usually scheduled monthly or quarterly depending on volume.
What to share when you call
- Restaurant type and kitchen volume.

- Whether you are doing new build, replacement, or service.
- Compliance status and any city notices.
- Photos of the kitchen and existing trap.

Toronto context
Grease trap and interceptor work in Toronto restaurants and food-service tenants is governed by Toronto Sewer Use Bylaw Chapter 681 — sizing has to match the kitchen, the cleaning frequency has to match the volume, and the documentation has to support a Toronto Public Health inspection. We handle the install, the service contract, and the paperwork.
What to confirm before approving grease trap work
- Sizing should match the actual kitchen volume, not just the smallest available.
- Cleaning intervals should be documented for compliance.
- Permits and city inspections should be coordinated.
Useful info on the call: kitchen volume, existing trap, and compliance status.
Frequently asked questions
How often does a grease trap need cleaning?
Most under-counter traps are cleaned monthly or every two weeks for high-volume kitchens. Exterior interceptors are pumped quarterly or per city schedule.
Do I need an under-counter trap or an exterior interceptor?
Volume drives the answer. Small to moderate volume kitchens often use under-counter traps. Higher volume or full-service restaurants typically need an exterior interceptor.
Can I clean it myself?
Some operators do, but city compliance often requires documented service by a licensed contractor. We provide the records that the city expects.
Will the city fine me if my trap is undersized?
Yes — under-sized or untreated grease can lead to violations and fines. Sizing correctly avoids that risk.
