What are the types of installation used by all plumbing contractors and certified testers?

As a condition of service all new residential homes and renewals must be fitted with an appropriate backflow prevention device in accordance with the Rules and Regulations of the City.

An approved testable backflow prevention device must be installed on all, commercial, industrial, irrigation systems, fire suppression systems, residential apartment buildings which contain five or more individual units, are multileveled and are jointly metered residential, non-residential service lines. A service line providing water to a farm for any purpose other than the residence is also considered to be non-residential and requires the installation of a backflow preventer device.

After the backflow prevention device is installed and water service initiated, an initial test must be performed within 30 days by a certified backflow tester.
