Backflow Prevention Testing

Backflow testing is one of the most important tests concerning the flow of water in your plumbing system you can do. These tests will tell you if the directional is correct or not. Though this may seem like an arbitrary test oh, The direction your water flows affects its cleanliness and usability.

Why is it So Important?

Backflow is the tendency of the directional flow of water to reverse. This means the direction in which the water in your pipes flows is turned on itself and the liquid begins to travel back to where it originated from.

This reversal increases the chances of the water intended for drinking, bathing, washing household items to become contaminated in a residential setting, or chemicals ending up in unwanted places in a commercial setting.
