What is a cross-connection?
A cross-connection is defined as any actual or potential physical connection between the public water system and any source that could contaminate the public water supply (i.e. plumbing fixtures, water utilizing equipment, or sprinkler systems). If improperly protected, contamination can result when a backflow event occurs; allowing contaminates to reverse flow from the fixture/equipment back into the customer’s water service and/or the public water system. Cross-connections, or potential cross-connections, are required to have devices installed to protect the quality of the water in the distribution system. These devices, called Backflow Prevention Devices, are installed on irrigation systems, fire sprinklers or other types of water uses where water could become contaminated.
