BACKFLOWS Meaning and
Definition
-
Backflows refer to the process or occurrence in which a fluid, especially water, flows in a direction opposite to its intended or normal flow. It is a phenomenon that takes place when the usual or desired flow direction is interrupted or reversed due to various factors or problems within a piping system or plumbing apparatus.
Backflows can occur through a cross-connection, which is an unintended point of contact between potable water and a source of contamination or pollutant. This can happen when there is a pressure drop in the water supply, causing the reverse flow of water and potentially allowing contaminants to enter the clean water supply system. Examples of cross-connections include irrigation systems, fire sprinkler systems, and industrial or commercial processes that involve chemicals or non-potable water.
The occurrence of backflows poses a serious risk to public health and safety, as it can result in waterborne diseases or contamination of the drinking water supply. To safeguard against backflows, backflow prevention devices are utilized. These devices, such as backflow prevention valves or vacuum breakers, are installed at specific points in the plumbing system to prevent the unwanted reversal of flow and protect the potable water supply from contamination.
Regular inspections, maintenance, and testing of backflow prevention devices are essential to ensure their proper functioning. Backflow prevention programs and regulations are enforced by local authorities to ensure the safety and integrity of the water supply system, minimizing the risk of backflows and associated hazards.

Etymology of BACKFLOWS
The term "backflows" is a compound word composed of two parts: "back" and "flows".
The word "back" originated from the Old English word "bæc", which means the rear part of something or the opposite direction. It can be traced back to the Proto-Germanic word "bakam".
The word "flow" comes from the Middle English word "flowen", derived from the Old English word "flowan". Both words refer to the movement of a liquid or gas in a specific direction.
So, when combined, "backflows" simply refers to the reversal or movement of a liquid or gas in the opposite direction than intended.
