Backflow Prevention

Backflow is the unwanted flow of contaminated water reversing into your clean potable water supply system. Backflow is typically caused when there is an abnormal drop in water pressure and contaminated water is siphoned back into your clean water supply. This is typically referred to as back-siphonage and/or back pressure.

I would like to give a big thanks to Sébastien C and Vincent B who Tourangeau sent to fix my plumbing issue. For the past three weeks I had lost hot water pressure in my house. Their plumbing skills were put to the test since I live in a house built in 1958. I was pleasantly surprised that they figured out the issue so quickly and fixed the problem. Excellent work!
