Have you received a letter from your city or region? Many industrial, commercial, institutional, and part 3 residential properties across Ontario now require backflow testing and device installation as mandated by the following regions:







What Is Backflow?

When there is more pressure in a private water system than usual, the water will flow in the opposite and unwanted direction.    


Backflow can contaminate the water from the private system forcing its way into the city’s system. You can not use this kind of water for human consumption, since it is completely toxic and unsuitable. There are two reasons for backflow happening. The first reason is a water main break or the other one, high demand at a water hydrant. 

There is always a necessity for testing the water since you cannot understand and be sure when the backflow is going to happen.     

Here are the most specific and important criteria that should be considered:

  • Checking the check valves in order to prevent backflow

  • checking the air-ports for getting open when they are needed

  • Checking the relief valves in order to get open before the pressure between the check valves is less than 2 PSL below the pressure at the inlet device.
