Restaurant Plumbing
Restaurant Plumbing, done properly
A blocked floor drain or a failed water heater during the lunch rush costs more than the repair. We plumb and maintain restaurants, quick-service and fast food locations, cafés, bakeries and ghost kitchens across Toronto — from new tenant fit-outs that pass inspection the first time, to after-hours repairs that keep you trading.
We understand City of Toronto sewer-use requirements, grease interceptor sizing and maintenance, backflow prevention testing and the inspections that come with opening or renovating a commercial kitchen. See also our commercial plumbing services and our guide to grease interceptors for Ontario restaurants.

Restaurant Plumbing — frequently asked questions
Do you work after hours so we can stay open?
Yes. We schedule restaurant work overnight, early morning or between services whenever possible.
Do restaurants in Toronto need a grease interceptor?
Food service locations that discharge grease to the sewer generally need a properly sized grease interceptor that is maintained regularly under the City's sewer-use requirements. We can size, install and maintain it.
Can you plumb a new fast food or franchise location?
Yes. We handle rough-in and finish plumbing for new quick-service and franchise fit-outs and coordinate inspections.
Do you test backflow preventers?
Yes. We install and test backflow prevention devices and provide the test reports.
What if our floor drain backs up during service?
Call (416) 700-3040 any time. We clear the line, camera-inspect it and recommend maintenance so it does not happen again.
