A backflow valve (also known as a check valve or backflow preventer) is a mechanical device used in plumbing systems to prevent the reverse flow of water. It ensures that water only flows in one direction, protecting the water supply from contamination or contamination risks.
Backflow can occur when there is a sudden change in pressure, like when water pressure in the municipal system drops (due to a pipe break or high demand) and allows water from potentially contaminated sources, such as a sink or irrigation system, to flow back into the clean water supply.
Backflow valves are essential for maintaining clean and safe drinking water in both residential and commercial plumbing systems.
