What is backflow testing?

(and why does my city require it?)

Your home's irrigation system is connected to the same water supply you drink from.

Backflow is what happens when water flows the wrong direction through that connection – pulling contaminants like fertilizer, pesticides, or soil back into your drinking water.

To prevent this, most cities along the I-35 corridor require homeowners with irrigation systems to have their backflow prevention device tested every year by a licensed technician.

It's not optional. It's not something you can skip. But it is something we can make very easy.

Do I need annual backflow testing?

If you own a home with an irrigation or sprinkler system in San Marcos, Kyle, or New Braunfels, the answer is almost certainly yes.

Your municipality posts annual testing due dates and tracks compliance. If your backflow preventer hasn't been tested – or if the report doesn't get filed correctly – you're out of compliance and that can mean fines or water service interruptions.

We know the requirements for each city and handle the reporting directly. You don't have to figure out what's due or who to send it to.
