What is the main purpose of installing backflow prevention assemblies?

Installing backflow prevention assemblies is fundamentally aimed at safeguarding the potable water supply from pollution or contamination. These assemblies play a critical role in ensuring that water flows in only one direction and that it does not reverse due to changes in pressure or other circumstances. By preventing the backflow of potentially hazardous substances from non-potable sources into the clean water supply, backflow prevention assemblies help maintain public health and safety standards.

Preventing contamination is essential because if backflow were to occur, it could lead to serious health risks from pathogens or chemicals entering the drinking water. This is particularly important in systems where there are potential cross-connections between potable and non-potable water sources, making the effectiveness of backflow prevention assemblies crucial for the integrity of the overall plumbing system.
