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.

25-year workmanship warranty
Every job Tornado Plumbing & Drains completes in Toronto and the GTA — repair, install, replacement, drain work, sewer work, fixture work — is backed by a 25-year workmanship warranty. The written terms are provided with every quote. If our work fails within 25 years of the install date, we come back and make it right.
Sizing and placement decide whether it works
A grease trap only does its job if it sits in the right spot in the drain run and is matched to your peak flow. Every greasy fixture — prep sinks, the three-compartment wash sink, the dish pit, and kitchen floor drains — has to tie in upstream of the trap, while toilets and hand sinks stay out of it. We confirm the retention volume and the required flow-control fitting against your fixture units so the unit captures fat, oil, and grease instead of letting it slug through during a dinner rush, and so the pump-out interval is realistic rather than a unit that needs servicing every few days.
When a kitchen needs grease trap work
- Opening a new commercial kitchen where the building permit or health inspection requires a grease interceptor before you can operate
- Repeated kitchen drain or floor-drain backups from grease coating the line between the sink and the main
- An existing undersized trap that fills within a day or two and forces constant pump-outs
- A cracked or corroded old steel interceptor that is leaking or no longer sealing at the lid
- A notice from Toronto Water or your landlord that the current setup is not compliant with the sewer use bylaw
- Adding a fryer, wok line, or extra prep sinks that exceed what the existing trap was sized for
- Persistent sewer odour in the kitchen from a missing, bypassed, or dried-out trap
What's included
- On-site assessment of your fixtures, peak flow rate, and available space to size the trap or interceptor correctly
- Permit application and coordination with the City plumbing inspector and Toronto Water sewer-use requirements
- Supply and installation of the under-counter unit or in-ground exterior interceptor, with proper venting and a flow-control fitting
- Tie-in of all greasy fixtures (prep sinks, wash sink, dish pit, floor drains) ahead of the trap and downstream to the sanitary line
- Final inspection, leak and flow testing, and a record of trap size and recommended pump-out interval for your maintenance log
- Removal and disposal of any old or failed interceptor, plus site cleanup
- Written 25-year workmanship warranty on the installation

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.
- Existing grease trap (size, age, condition).
- Whether you are doing new build, replacement, or service.
- Compliance status and any city notices.
- Photos of the kitchen and existing trap.
- Operating hours and access.
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.
