The Best Methods of Backflow Prevention and Why It MattersPosted by July 7th, 2016
Backflow is a very important concept to understand for those who have pipes that supply water. Backflow occurs when dirty water travels backward through the pipes, entering the clean water. This obviously leads to contamination and sanitation concerns. Backflow may even bring invisible contaminants into your pipes, causing damage to the health of your residents or customers without your knowledge. Luckily, experts have developed effective methods of backflow prevention.
In nearly every case, backflow will occur because of a drop in the water pressure. When this happens, the water from a dirty source will be sucked back into the system, mixing with the clean water supply. Unfortunately, drops in water pressure are more common than most home or business owners realize. They can happen if a fire hydrant nearby is opened, a water main breaks, or there is an issue at a pumping station nearby. Because backflow is typically caused by water pressure drops, most backflow prevention methods rely on preventing or at least tracking this drop and taking action automatically.
At Cynergy Mechanical Ltd., we can also help with backflow prevention systems for multi-residential sites. There is a bylaw in Toronto that requires annual testing for backflow systems such as these, so make sure you contact us yearly to take care of this important maintenance task.
