Backflow Testing

Backflow Testing

As a homeowner or business owner, you may have gotten a notice to test your backflow preventer. Many utility providers require annual testing of your backflow preventer device. But as you’re reading the notice, you’re becoming more and more unsure about what it is and what you need to do to get it done. Luckily, we’re here to answer the questions you might be asking yourself. 

 

This is a standard backflow device. (It is usually located under a green box or fake rock.)

 

 

 

 

 

 

 

A backflow preventer is a check valve unit installed on your pipes that allows water to only flow in one direction. Backflow preventers ensure that contaminated water does not reverse flow and enter in to the clean water lines. It can occur at any cross-connection between clean and dirty water lines. The dirty water may contain hazardous materials like human waste, pesticides, or chemicals, so you can see that a defective device can poses a very serious health concern. 
 
If you are in need of a backflow test for your utility company, we have you covered. We can test in the entire Mid South region and we have 5 licensed testers on staff.
