Your backflow device is the first line of defence to protect you and your family’s drinking water. Water leaks, water main breaks or drops in pressure can cause water from your municipality to back up into your home and that water could contain harmful contaminants. A backflow prevention company like Alberta Indoor Comfort (previously Sears) can help ensure you and your family get clean, safe drinking water every time you turn on the tap.

When to Get Your Backflow Device Tested

In many places, homeowners and business that have backflow devices are required to have them tested regularly. Your municipality probably has a schedule for when people need to get backflow preventers tested, but usually it’s once a year. If you’re not sure when or how to get your device tested, call a reputable backflow repair company and ask them for help.

How Backflow Testing Is Accomplished

Backflow testing is a simple task, but one a certified inspector must do. The inspector shuts off the #2 valve and puts a test kit on the device. The testing kit samples the water left in the backflow, and after they do the test, they turn the water back on.

Does your kitchen always stink of garbage? Our garbage disposal services may solve that problem.

Dangers of Backflow

As mentioned, backflow occurs when there is a sudden change in water pressure, such as when a firefighter is using a hydrant. The pressure change causes water to flow back into the opposite direction, and most times, this water is filled with chemicals and other contaminants that aren’t safe for drinking. The problem is that people rarely know they’re drinking contaminated water until it’s too late. While it’s rare, some people have contracted fatal illnesses from contaminated water, which is why it’s essential for the health and safety of your family to have adequate backflow preventers and to ensure they’re fully functional.
