Solutions for Repairing a Cross-Connection

Direct pipe cross-connections are prohibited due to the inherent threats to the safety of our water system.
It's easy to eliminate a cross connection if you discover it by disconnecting the pipe and re-routing or re-plumbing it.
As a last resort, installation of an approved backflow prevention device will provide a viable solution.
