A. Each new or existing single-family residential service connection shall be reviewed using the technical manuals for possible cross-connections and may require an approved backflow prevention assembly per GHMC 13.06.130 adjacent to the water meter on the consumer’s side of the service connection. If a single-family residential service connection includes an irrigation system, a double check valve backflow prevention assembly shall be installed adjacent to the water meter on the consumer’s side of the irrigation system service connection.

Each new non-single-family residential service connection shall install an approved backflow prevention assembly per GHMC 13.06.130 adjacent to the water meter on the consumer’s side of the service connection. If the use for all inhabitable spaces within a non-single-family residential structure is not known at the time of plumbing permit application, a reduced pressure backflow prevention assembly shall be installed adjacent to the water meter on the consumer’s side of the service connection.
