What is a RPBPD and when are they required?
A reduced pressure backflow prevention device (RPBPD) prevents water from flowing in reverse and potentially contaminating the water in the District's mains. RPBPDs are required on all services in industrial and commercial areas, on residential services with houses greater than 3 stories or with residential fire sprinklers, and at all sites that also have a well or other potential water quality hazard. RPBPDs are installed and maintained by the District. RPBPDs are installed approximately 18-inches above ground and are typically located directly behind the meter preferably in landscaped areas.
