B. Application. These Rules and Regulations shall apply to all Premises served by the City's public potable water system.
C. Policy. The Water Purveyor shall be responsible for the protection of the public water supply system from Contamination due to back-pressure or back-siphonage of contaminants through the Customer's water Service Connection.

The water Consumer shall immediately install such approved assembly or method at his own expense. Failure, refusal or inability on the part of the Consumer to install such assembly or assemblies immediately shall constitute grounds for discontinuing water service to the Premises until such assembly or assemblies have been installed and tested per this regulation.
