What is Backflow?

Backflow is the unintended reversal of the flow of water from any source in a water system. It occurs when the supplied water pressure is lower than the internal plumbing system. Incorrect backflow may allow contaminated water from your industry to be drawn back into the water supply system. As a result, it can cause significant health issues and legal problems for the industry owner.

What Causes Backflow?
There can be many causes of Backflow in the industries that work with unique processes, chemicals, equipment, agriculture and manufacturing. Water distribution systems are designed so that water flows in only one direction. However, it is possible for the system of delivery to breakdown or develops complications that stop the water from flowing in its intended direction. When this occurs, water ends up flowing in the opposite direction.

Listed below are the major causes of backflow in commercial properties.

  • Certain circumstances, such as a burst pipe or use of a fire hydrant in the street, may cause the pressure to drop which causes the water to flow reverse.
  • Back pressure is the term used for the pressure that pushes gas or water in the ‘wrong’ direction. This most often happens when heaters are not provided with efficient vents or outlets. It causes the pressure inside to rise at the time when the water is being heated up.
  • Back siphonage arises when the pressure in the water supply piping becomes significantly lower than the external pressure causing water to flow the other way.
  • Sewerage pipe damage
    The sewerage pipes are carrying the wastewater from your home to the local water system. Because everything is subject to wear and tear, these pipes suffer damage over time. Once they do, it will cause backflow. The signs are very obvious, so it is possible to take action right away. Foul smell and leaks from your drains are the primary indicators of sewerage pipes damage.
  • Local source damage
    There are also some rare occasions where the cause of the problem cannot be detected inside your property or business. Sometimes, there is nothing wrong with your plumbing system. The issues may lie in with the city or local sanitation, and a backup within the system may have caused the backflow into your business.


How to  Prevent Backflow?

All industrial properties are identified as a potential backflow risk and need to be aware of their responsibilities to prevent backflow. Backflow usually occurs during routine repair or maintenance or where connections have been illegally installed. To help prevent these incidents from occurring, more cities and municipalities are commanding that backflow prevention devices be installed.

A backflow prevention device works by preventing water from flowing in the opposite direction  through a series of check valves. Backflow is particularly at risk during times of changing water pressure or other fluctuations and changes. With a correctly installed and properly maintained backflow preventer, your water is clean, clear and safe from harmful contaminants.

Backflow Prevention Regulations

The water supply by law mandates that all industrial properties in Toronto should have backflow prevention devices. Contact us today for detailed information on various situations whereby your industries would be required to have a backflow prevention device installed and tested.

Backflow Prevention Devices for Industrial Business

The type of device that is suitable for your industry is based on the degree of hazard your industry presents to the water system.

  • High Hazard
    These valves will consist of Reduced Pressure Zone Device (RPZD), that are installed in high risk areas. These valves must be serviced and tested annually.
  • Medium Hazard
    These valves will consist of a testable double check valve (DCV), which are installed in areas that present a medium risk. This device prevents both siphonage and backpressure. These valves must be serviced and tested annually.
  • Low Hazard
    These are non testable devices which could be a backstop, vacuum breaker assembly (VBA) or dual check valves. They are installed in areas that present a low risk and if these devices fail to service, they are replaced.


Backflow Prevention Devices Testing Repair

Every industry that has a backflow prevention device installed needs to have the device tested by a certified plumber at least once every year. This will ensure your business meets all standards of compliance. Our team can perform your yearly testing and installing backflow systems that protect you and your industries.
