Backflow Preventor

• (4) The Contractor V may install the cross-connection backflow prevention device as defined in this chapter on new installations. The retrofitting of a backflow device on an existing fire protection system will cause a reduction in available water pressure and probable system malfunction. The development of aboveground fire protection system hydraulic calculations is a task of the Contractor I and II, as defined in this chapter. Accordingly, a Contractor V is expressly prohibited from retrofitting cross-connection backflow prevention devices on an existing fire protection system, and only a Contractor I or Contractor II who is tasked to recalculate the system and take corrective actions to ensure that the system will function with the available water supply may retroactively install these backflow devices on existing fire protection systems.
