Backflow Basics 

What is a backflow assembly, and why do I need one?

Put simply, a properly working backflow prevention assembly keeps water downstream from mixing with water upstream.  Any debris in the line, wear or damage to seals, or failure of other internal components, can allow water to pass freely and contaminate the public water system with microbes and hazardous chemicals.  This can happen with lawn sprinkler systems, hoses immersed in chlorinated pools or watering troughs, fire sprinkler systems, soda machines, dental or medical clinics that work with body fluids, etc.

Annual testing ensures that your assembly is working correctly.  The State of Texas requires backflow assemblies to be tested at least annually.  As certified backflow testers, we test the valves and then report the results to you and the water district.

To schedule backflow testing or to have backflow devices installed or repaired, call us at 972-723-5535 or email us at backflow@alliedflow.com.
