Backflow Preventer Raleigh NC
The unwanted reverse flow of water or substances into a potable water system, poses a significant risk to water quality. To counter this, certified backflow preventers are crucial installations to prevent contamination in case of a backflow incident. The two primary hydraulic reasons for backflow are backpressure and backsiphonage.
Consider, for instance, the critical need to keep water in an irrigation system separate from potable water. Irrigation water, with its contact with pesticides and fertilizers, is unfit for human consumption.
Recognizing this, plumbing codes classify irrigation systems as hazards, necessitating separation through backflow prevention assemblies. These assemblies require periodic backflow prevention testing and maintenance by certified personnel to ensure ongoing protection.
Installation of these assemblies comes with specific criteria to guarantee continuous functionality. They are typically installed above ground and, in many cases, outside. In winter, when irrigation systems are shut off, some installations require the water to remain on, leading to the need for enclosures to protect the assemblies from environmental effects.
