Our training courses help you to understand the risk that Backflow poses and provides what remedial & cyclical procedures should be implemented to minimise the risk of Backflow.
What Is Backflow?
Backflow is an unwanted flow of water in the reverse direction. It can be a serious health risk for the contamination of potable water supplies with contaminated/foul water.
The undesirable reversal of flow of water or other substances usually occurs through a Cross Connection into the consumer’s potable water system.
Backflow may be due to either: Back siphonage; or Backpressure.
How Can It Occur?
For a drinking water (potable water) supply to become contaminated via backflow, two things need to happen simultaneously:
- A physical link (cross-connection). This may be provided by direct plumbing connection or submerged inlet
- A pressure differential. This may be caused by high pressure on the contaminated side (backpressure) or a negative pressure on the supply side (back siphonage)
Back siphonage means; backflow due to a reduction in system pressure in the supplier’s distribution system and/or consumer’s water system.
Backpressure means; a pressure on the consumer’s side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow. This could be caused by a pump, boiler, or other means.
