(A) All proposed installations of fire suppression systems shall be reviewed by the Director of Public Works to determine the appropriate type of backflow prevention assemblies required.
(B) All proposed fire suppression systems requiring an antifreeze solution shall use a pharmaceutical grade antifreeze. The customer shall provide to the Director of Public Works annually a certification identifying the type of pharmaceutical grade antifreeze which is used. A double check valve backflow prevention device shall be installed in an approved manner.
(C) A double check valve of an approved type shall be installed on all proposed fire suppression systems not utilizing antifreeze, but this may be done only when there are no other cross-connections.
(D) (1) All existing fire suppression systems shall meet the requirements of divisions (B) or (C) above, whichever applies. An inspection by a certified fire suppression specialist shall be done to determine whether pharmaceutical grade antifreeze(s) have been utilized. This shall be done at the expense of the customer.
(2) If it cannot be certified that only pharmaceutical grade antifreezes have been used, then a reduced pressure principle backflow prevention assembly shall be installed as approved by the Director of Public Works. This also shall be done at the expense of the customer.
(E) In the event cross-connections such as those found in using auxiliary water supply systems or in providing other water additives such as foaming agents are necessary for the proper operation of the fire suppression system, then a reduced pressure zone backflow prevention assembly shall be installed in an approved manner unless the agent possesses a non-health hazard. If the agent possesses a non-health hazard, then a double check valve assembly can be used.
