(A) No person shall install or maintain a water service connection to any premises where a booster pump has been installed on the service line to or within the premises, unless the booster pump is equipped with a low pressure cut-off designed to shut off the booster pump when the pressure in the service line on the suction side of the pump drops to 20 pounds per square inch gauge or less.
(B) It shall be the duty of the water customer to maintain the low pressure cut-off device in proper working order.
(Prior Code, § 52.083) (Ord. 95-38, passed 12-18-1995) Penalty, see § 52.999
(A) Yard hydrants or hose bibs which would be used by the customer to provide water to mix pesticides, fertilizer or other chemicals for direct use or aerial application to surface areas shall be equipped with an antisiphon vacuum breaker or where a cross-connection could occur.
(B) All underground lawn and garden sprinkler systems shall be equipped with an approved backflow prevention device, but annual testing is not required.
(Prior Code, § 52.084) (Ord. 95-38, passed 12-18-1995) Penalty, see § 52.999
(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.
(Prior Code, § 52.085) (Ord. 95-38, passed 12-18-1995) Penalty, see § 52.999

(C) The Director of Public Works shall keep a current list of all certified suppliers and their appropriate list of makes and models of backflow prevention devices which the Director of Public Works has deemed approved.
(D) (1) The Director of Public Works may require a strainer and a manufacturer’s air gap device of approved type and size to be installed in conjunction with required backflow prevention devices.
(2) The installation of strainers shall preclude the fouling of backflow device(s) due to foreseen and unforeseen circumstances occurring to the water supply system such as water main repairs, water main breaks, fires, periodic cleaning and flushing of mains causing fouling of backflow device(s).
(3) A manufacturer’s approved air gap device will ensure that the proper air gap maintained at all times.
