Plumbing Code Update: Basics Of Cross Connection Control

“Cross connection” means a connection or potential connection between any part of a water supply system and another environment containing substances in a manner that, under any circumstances, would allow the substances to enter the water supply system by means of back siphonage or back pressure.
When potable water piping connects to various plumbing fixtures or water utilizing equipment a cross-connection is created. If improperly protected, contamination can result when a backflow event occurs; allowing contaminates to reverse flow from the fixture/equipment back into the potable supply water piping.

In this class we will:

• Review and discuss the corresponding code section for cross connection control.
• Review devices that automatically prevent backflow from a contaminated source into a potable water supply system.
• Review testable assemblies type backflow preventers consisting of an arrangement of components.
• Review methods, which prevent backflow from a contaminated source into a potable water supply system.
• Examine real life case studies of cross-connections and apply code knowledge as to how they may have been prevented.
