What is water backflow?

Imagine your clean drinking water flowing backwards – that's backflow. Instead of dirty water draining away, it can reverse direction, potentially contaminating your water supply and forcing a service shutdown.

.

How Does it Happen?

Any connection between your clean water system and a non-potable water source (like fire sprinklers or irrigation) creates a potential pathway for backflow. This is called a cross-connection. When pressure changes occur within the system, contaminants can enter the clean water supply through these connections.

.

A Brief History of Backflow Prevention

• Early Days (1930s): Rudimentary pressure vacuum breakers were developed in Los Angeles, marking the first attempts at backflow prevention.
• Evolution of Double Check Valves (1930s-1950s): Double check valves emerged and gradually evolved into their modern form, becoming the primary backflow prevention device for many years.
• Advancements (Mid-20th Century): The introduction of Reduced Pressure Zone (RPZ) devices and the categorization of different hazard levels significantly improved backflow prevention technology.
