Backflow Prevention in Winnipeg

Homes in Winnipeg are among the many homes across Canada that are at risk of flooding. With the rainy season upon us, it’s important for you to be aware of the possible home risks associated with flooding – and it’s our job to fill you in when it comes to backflow. So without further ado, let’s get into it!

What is backflow?

In most cases, drinking water flows from a city’s distribution system into your property’s private water system. Backflow occurs when the water flow undergoes a reversal, typically because of changes in water pressure. This backflow can cause pollutants to enter your drinking water system. As winnipeg.ca puts it, “Ultimately, backflow has the potential to cause the contamination of the entire public water supply, posing a risk for anyone using the water for drinking, cooking, bathing, or other purposes.” Clearly, we don’t need to tell you that this is a big deal – but the good news is that most cities, Winnipeg included, have regulations and testing in place to ensure safe drinking water is accessible to their citizens. So while there’s no need to panic, there are still steps you should take to protect your home using backflow prevention.

How do I prevent backflow in my home?

If you purchased your home or moved into a new build, chances are good that your property had to satisfy testing requirements per the city’s Backflow Prevention Program. But to err on the side of caution, or if you live in an older home, it’s a good idea to check with the city to see what you may need to do, and depending on their answer, give We Love Plumbing a call for an estimate and to book the installation of your backflow prevention valve.

Didn’t you say this had something to do with flooding?

We sure did! Here’s how it works: Backflow valves are installed where the sanitary pipe exits your home. The valve normally allows wastewater to flow out of your property to the main sewer near your street. But if that sewer is backed up and the contaminated water flows back toward the house, the valve closes and thus prevents the water from re-entering, and flooding, your basement.
