Winston-Salem Backflow Prevention & Testing

What Is Backflow?

Backflow is a term used to describe the flow of water in the opposite direction of its intended direction. This can occur when the pressure in the water supply system drops, causing water to flow in the opposite direction. This can cause contaminated water to flow back into the clean water supply. Backflow can occur in any plumbing system, but it is most common in homes and businesses that have a cross-connection between the water supply and a source of contamination.

There are two types of backflow: backpressure and backsiphonage.

  • Backpressure occurs when the pressure in the water supply system is greater than the pressure in the plumbing system. This can cause water to flow back into the clean water supply.
  • Backsiphonage occurs when there is a sudden drop in pressure in the water supply system. This can cause water to be siphoned back into the clean water supply.

What Is a Cross-Connection?

A cross-connection is a connection between the water supply and a source of contamination. This can occur when a plumbing system is not properly installed or maintained. A cross-connection can also occur when a hose is left in a bucket of soapy water or when a hose is submerged in a swimming pool or hot tub. A cross-connection can also occur when a plumbing system is connected to a non-potable water supply, such as a well or a cistern.

A backflow preventer is typically made of brass or bronze and is installed in a vertical position. A backflow preventer is typically installed in a valve box or a meter pit.
