Many of our blogs and Facebook posts center on DIY projects and water reclamation/water recycling. Intentional water reclamation is a Good Thing. But when it's taking place unannounced through an unwanted hydraulic event called 'backflow'...well that's a bad thing. Backflow occurs when non-potable water enters one's water supply as a result of improperly connected and causes potentially deadly contamination. Understanding backflow and the fix – aptly named 'backflow prevention' – is important.
According to http://tripleabackflow.com, backflow happens when "man-made contaminants enter the drinking water through cross-connected plumbing on private property. contaminants can cause serious illness and the owner can be held liable for damages." In the vernacular, improperly connected plumbing causes your drinking water lines to hook up with your sewage, creating a condition where the good water and the bad water co-mingle in your drinking water. Yuuuuuck.
Cross-Connected Plumbing Defined
"A cross-connection is a point in the plumbing where ones drinking water is connected to a contaminated source and the contaminated water can flow back through the connection." Typically, cross-connections can include (but are not limited to) the following:
· Sprinkler systems
· Utility sinks/wash basins
· Water conditioners
· Boilers, cooling towers and chillers
Backflow Prevention – It Matters.
If you have a home or business sprinkler system (lawn or fire) or any other plumbing situation where potable water is connected to a non-potable application, a backflow prevention device is a requirement. Two types are available for use with sprinkler systems: a pressure vacuum breaker (PVB) for lawns that are mostly level and a reduced pressure assembly (RPA) for lawns that are hilly and uneven. Note that once you have a backflow prevention installed, state and city codes require the backflow prevention devices to be tested annually be a licensed inspector.
