Fire Department Connection Assemblies

The ParkUSA® BackFlo™ is a water cross connection prevention system designed to protect the public water supply from hazardous cross contamination. Measures the volume of water usage for residential, municipal, commercial, and industrial applications.

Our modern community water supply system is designed to ensure that water flows to properties and buildings under pressure. This community water network contains many users where there is a risk to public health if there is a cross-connection between the water supply and a contaminated source. A cross-connection can occur where there is a pressure drop in the water main. This pressure drop causes a vacuum and siphons of entrainment water from end-users into the public water supply. The backflow preventer is generally located inside the property line of the end-user’s facility and is installed in a concrete vault or on a concrete pad for protection and accessibility.

Municipalities around the country may require unique cross connection arrangements and specifications. Engineers rely on ParkUSA’s code knowledge and technical expertise to specify the right equipment.

Simply stated, a backflow preventer is a check valve device that’s installed on a potable piping system that allows water to flow in one direction, but never in the opposite direction. Its sole job is to prevent drinking water from being contaminated due to backflow. Backflow of water is caused by the pressure differential between the upstream (water main) and the downstream of the backflow device.

Water pressure can be affected when: 

  • There is a break in the water main.
  • Water is being pumped from the main water supply during a fire.
  • A customer is using water at a higher pressure than the pressure supplied.
  • The water outlet at the property is higher than the water main, causing constant back pressure.​
  • Heavy water use downstream reduces water pressure upstream.​
