Why You Should Care About Backflow Testing in Your Home
Backflow happens when dirty water flows the wrong way and mixes with your clean water. This can be dangerous because it could bring harmful chemicals, waste, or bacteria into the water you drink and use every day. That’s why backflow testing is so important—it helps keep your water safe.
Back-Siphonage and Backpressure
There are two main ways backflow can happen. One is called back-siphonage, which is when a drop in water pressure causes dirty water to get sucked into the clean water pipes. The other is called backpressure, which is when water is pushed backward into your clean supply, usually because of equipment like boilers, pumps, or irrigation systems that can fluctuate water pressure in your water system.
It helps keep your water safe.
To stop this from happening, there are special devices you can install in your home. Some are simple, like leaving a gap between a faucet and a sink (called an air gap), while others are mechanical valves that help keep the flow going in the right direction. In many places, including Ontario, certain types of these devices are required and must be tested each year to make sure they’re working properly.
Even with the right equipment in place, problems can still pop up. Parts can wear out or break over time, and things like corrosion or buildup can affect how the system works. If these issues aren’t caught early, they could lead to contaminated water in your home.
Many common household items—like sprinklers or garden hoses—can cause backflow if they’re not installed correctly or don’t have the right protection. That’s why it’s a good idea to have your system checked once a year by someone who knows what they’re doing.
