Control and Elimination of Cross Connections: Panel Discussion

This panel discussion of the control and elimination of cross connections covered the following topics: backflow prevention devices such as a double check valve assembly, and the reduced‐pressure backflow prevention device; air gap separation as compared to backflow prevention devices; standards for backflow prevention devices; and, a proposed manual of recommended practices for backflow control. Conclusions indicated that any one of the three backflow prevention devices discussed will provide full protection as long as the device continues to function as it was intended to. Thus, a major problem in backflow prevention is the critical need for a regular maintenance program, and it is recommended that a permanent committee on cross‐connection control be established.
