Do I need a drain permit for installing backwater valve in Toronto?

Installation of a backwater valve in multi-unit and non-residential buildings necessitates a separate drain permit. Please consult the Plumbing and Drain Permit Stand-Alone Application guide for details on submission requirements.

Premises that may Need a Backflow Device

The backflow of water can be a serious problem for Toronto’s water supply. According to the Ontario Building Code, building owners and site managers “shall ensure that backwater valves are installed in every plumbing fixture or branch line connected with a municipal drinking-water main, where necessary.” This is also true for other types of premises:

Cafes and Restaurants
Shopping Centres and High-rise Buildings.
Mechanic Workshops
Car Washes
Swimming Pools
Laundries and Dry Cleaners
Golf Courses or Sporting Ovals
Caravan Parks
Manufacturing Premises
Medical Facilities Such as Hospitals and Veterinary Clinics

I had to call a plumbing company because there was a bad smell coming from the kitchen sink that wouldn't go away. I'm really glad I called Plumber To Your Door. George arrived within 2 hours, found the cause much faster than I expected, and left the whole area clean when he finished. They even followed up afterward to make sure everything was still working well. I wouldn't hesitate to recommend them.
Enny, we truly appreciate your kind words and the time you took to share your experience with us. It means a lot to our entire team to know that we were able to help and provide a service that met your expectations.

We had an emergency situation when our main drain burst in the basement, and Plumbing truly came to the rescue. From the moment we called, they were responsive, professional, and incredibly reassuring during a very stressful time. Their team arrived quickly, assessed the situation with confidence, and got to work right away. What really stood out was their expertise and efficiency; they clearly knew exactly what they were doing, and they handled everything with care and precision. They also took the time to explain the issue and the repair process, which we really appreciated. Not only did they fix the problem promptly, but they also made sure everything was cleaned up afterward, leaving our basement and lawn in great shape considering the circumstances. It’s rare to find a company that combines skill.
