Class2 - A fire protection system that is the same as a Class 1 system; except that a booster pump is installed in the fire protection system, and no outlet is located between the booster pump and the Water System. (Note -Booster pumps alone do not affect the potability of the system. In Class 2 fire protection system, it is necessary to avoid low or negative pressures that can occur by excessive flow through the booster pump. A minimum pressure of 20 psig on the inlet side of the booster pump shall be maintained through proper design, construction, operation and maintenance in addition to the use of a low pressure cutoff switch, pump modulating valve, or other automatic device.) Class 3 - A fire protection system that is the same as a Class 1 system; except that a storage tank, fire pump that pumps from a covered above-ground reservoir or tank, or pressure tank is connected to the fire protection system. (Note - All storage facilities must be filled only from and connected exclusively to the Water System. Furthermore, water in 14 the storage facilities must be maintained in a potable condition.) Class 4 - A fire protection system that is the same as a Class 1 or Class 2 system; except that an auxiliary water supply is on or available to the properties, or there is an auxiliary water supply designated by the Utilities Department within a radius of 1,700 feet from a pumper connection to the fire protection system. (Note - Connection to an auxiliary water supply cannot exist in a Class 4 fire protection system.)

Class 6 - A fire protection system that is connected to a water service line from the Water System if the water service line is not used exclusively for fire protection. 4.7 BACKFLOW PREVENTION ON FIRE PROTECTION SYSTEMS The Water System shall be protected by an approved method of backflow prevention in water service lines to fire protection systems, regardless of backflow prevention requirements in other water services on the premises. A. Classes 1 & 2 An approved DDCVA is required as the minimum backflow prevention in the water service line to a Class 1 or Class 2 fire protection system, if the owner can document that there are no potential high hazards on the premises, and all fire protection system water storage vessels are maintained in a potable condition. An approved DRPZA is required in the water service line to the fire protection system if there is a potential high hazard on the premises. B. Class 3 An approved DDCVA is required as the minimum backflow prevention in the water service line to a Class 3 fire protection system, if the owner can document that there are no potential high hazards on the premises, and all fire protection system water storage vessels are maintained in a potable condition. An approved DRPZA is required in the water service line to a Class 3 fire protection system if the industrial or domestic water system could potentially be subjected to a high hazard. C. Classes 4. 5 & 6 An approved DRPZA is required in the water service line to a Class 4 or Class 5 fire protection system. D. Retrofit Of Existing Systems This applies to an existing fire protection system which is modified, extended, or enlarged. Such systems include a modification or 15 n extension to an exiting network (distribution piping, sprinkler heads control valves, etc. are added to or replaced in an existing system), or where an additional fire protection system (new feed line, riser, control valve, distribution piping, sprinkler heads, etc.) will connect to a fire main which has an existing cross connection control device. The minimum protection for cross connection control for existing systems is the same as listed for new systems, except as noted below for Class 1 and 2 systems only. The installation of properly sized assembly may cause an excessive pressure loss in some altered Class 1 and 2 systems. Such loss could make the system noncompliant with NFPA Pamphlets 13 and 14 as adopted. The Responsible Managing Employee shall document to the Approving Authority that reasonable modifications will not compensate for the additional loss. The documentation shall contain a listing of the minimum flow and pressure, headloss summary, desired and calculated sprinkler head output and a summary of the options examined to reduce headloss. For these installations, if not already installed, the existing cross connection control device will be replaced with two check valves in series (one of which can be the alarm valve), each valve meeting AWWA C508-82, UL 312-88, or UL 193-88, or • the latest versions thereof, and equipped with a resilient seating surface. The valves or adjacent piping shall be equipped with a sufficient number of resilient seated test cocks (minimum diameter of one quarter to one-half inch) to determine the effectiveness of each valve (there shall be no leakage past any check valve). Sufficient isolation valves - one valve upstream of the valves and one valve downstream of the valves - shall be present or added to the system to permit this testing. Existing fire protection systems which are not being modified, enlarged, or expanded are not required to upgrade to comply with this policy. 4.8 CONSUMER RESPONSIBILITIES The consumer shall: A. Eliminate all cross connections or install an approved backflow prevention assembly on the water service line. B. Immediately correct any malfunction of the backflow prevention assembly. C.
