Reasons for Backflow Testing

After a service interruption, backflow testing will help us figure out if the water supply in your home is safe for drinking, cooking and bathing. Whether there has been an extreme weather event, water main break, nearby construction or some other issue, any interruption requires backflow testing and certification to ensure the water is safe from bacteria and other harmful contaminants.

Backflow Testing Basics

The backflow testing process includes our technicians testing your water to determine what types of bacteria, sediment or debris are present in your water, and whether backflow has taken place. Although the thought of an interruption in water flow may not seem like a big deal, your water must be tested in order to determine if it is safe to use. Our technicians are certified to test for backflow and will show up at your home with a backflow testing kit to get to work.

Better Safe than Sorry

If you live in an area where backflow is common, you may want to consider having a backflow device installed in your plumbing system to help prevent this from happening in your home. If you are concerned that your home has a backflow problem, then it’s always best to err on the side of caution and call for professional service.
