What is a Backflow Prevention Device?

Why is it so important to replace a PVB right away if it is leaking or broken? Well, it all has to do with the important work this part does.

*Backflow preventers protect your drinking and household water from contaminants* that could be found in your irrigation system. Things like fertilizers, pesticides, and other products applied to your lawn inevitable enter your irrigation system. A backflow device ensures this water doesn't back up into your household water supply through the plumbing.

How Would Water From Irrigation Even Get Into the Plumbing?

Understanding the importance of a backflow device or pressure vacuum breaker requires a little science lesson.

spring texas pressure vacuum breakers for irrigationA "backflow" occurs when water pressure conditions fluctuate within the water system and the water flow reverses direction and causes a suction that will pull dirty water in - mixing it with the clean water supply. Keeping your family and pets safe from contaminants in the dirty water, requires a properly installed and functioning backflow device which could be a pressure vacuum breaker (PVB) or a reduced pressure zone valve (RPZ). Backflow preventers are required at most cross-sections in commercial, residential and industrial water systems to protect the municipal water supply. When unequal water pressure occurs or pressure fluctuates, the valve prevents dirty water from flowing backward into the clean water supply. Your irrigation system is a water system which requires a backflow preventer.
