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

Chemical Plants

The sink filled up and wouldn’t drain at all. I tried a few things myself first, but nothing worked. I had to call Matteo from Plumber to your Door who came within 2 hours and cleared it properly. He tested it more than once before heading out. Works perfectly now.

Plumber provided a quote after inspection, then raised price at the end of service. Do not recommend

I only realized the valve was stuck when I actually needed to shut the water off. Chris came later that day and didn’t make it a big job, just handled it and replaced it. What I liked is he checked it twice before leaving.

These guys did a great job of unclogging my kitchen sink. The blockage was way down the drain. They had to snake all the way through the basement. Came on very short notice and kept it clean. Would call again!

I honestly thought my garbage disposal was completely broken. Chris came by and showed me it was actually jammed. He got it running again without replacing anything. I appreciated the honesty because another company might have tried to sell a new unit. Very good service.

After working with other technicians before. I can say this has been the most smooth, efficient, reasonable, and friendly service I have received.  They were early for the appointment, which I am grateful for as most technicians were always 1-2 hour late from my experiences. Got straight to work and reasonable with pricing. Double, triple checking to see if everything is running smoothly. They communicate well through email and definitely provided the best customer service.  Highly recommend!

This will sound too good to be true as a rave, but I was going crazy with other plumbers who put me on hold, one who gave me an estimate of $1200...! I went with your firm, and George came early, sized up the problem instantly, brought in his equipment and solved in something like TEN MINUTES. And for a quarter of that other operation's outrageous estimate. He also fixed a smaller issue at no extra charge. I am EXTREMELY happy with the job done!

One of our heating lines was having a different pressure and certain areas weren’t warming properly. Plumber To Your Door sent someone who knew exactly what to check. The issue was corrected without replacing unnecessary parts. We’re satisfied with how it was managed. Good job.
