(a) The type of protection required under Section 1048.05(b) shall depend on the degree of hazard, which exists as follows:
(1) A required air gap separation and an approved reduced pressure principle back flow prevention device shall be maintained where a public water system may be contaminated with substances that could cause a severe health hazard;
(2) A required air gap separation shall be maintained or an approved reduced pressure principle backflow prevention device shall be installed where a public water system may be contaminated with any substance that could cause a system or health hazard or a pollutional hazard.
(b) The type of protection required under Section 1048.05(c) shall be a required air gap separation or an approved interchangeable connection.
(c) Where an auxiliary water system is used as a secondary source of water for a fire protection system, the provisions of subsection (b) of this section for a required air gap separation or an approved interchangeable connection may be waived by the Public Service Director and the Ohio E.P.A., provided:
(1) At premises where the auxiliary water system may be contaminated with substances that could cause a system or health hazard, a public water system or a consumer’s potable water system shall be protected against backflow by installation of an approved reduced pressure principle backflow prevention device;
(2) At all other premises, a public water system or a potable consumer's water system shall be protected against backflow by installation of an approved reduced pressure principle backflow prevention device;
(3) A public water system or a consumer's potable water system shall be the primary source of water for the fire-protection system;
(4) The fire-protection system shall be normally filled with water from a public water system or a consumer's potable water system;
(5) The water in the fire-protection system shall be used for fire protection only, with no other use of water from the fire-protection system downstream from the approved backflow prevention device.
(d) Type of Backflow Protection Required; Commercial Water Services.
(1) An approved backflow prevention device of the type designated shall be installed on each domestic water service connection to the following types of facilities unless the Public Service Director determines that no real or potential health, pollutional system hazard to the public water system exits.

(e) Type of Backflow Protection Required; Fire Protection Service. An approved double check valve assembly device or the use of a reduced pressure principle backflow prevention device shall be installed on each fire protection service to any premises unless the Health Commissioner determines that no real or potential health, pollutional or system hazard to the public water system exists. The double check assembly device must meet all of the following requirements before it can be approved by the City Water and Fire Divisions.
(1) Water from the downstream side of the double check valve assembly device shall be used for fire protection only.
(2) There shall be no regular use of water downstream from the double check valve assembly device other than for fire system make-up water.
(3) The fire system shall be filled with water from the public water supply only.
(4) The public water supply must be the primary source of water for fighting fires.
(5) The water system must contain no additives. Provided, however, where the fire protection system contains any of the following components a reduced pressure principle back flow prevention device shall be installed between such component and the rest of the water system so as to isolate such component from the rest of the water system:
Auxiliary Water System
Anti-Freeze Legs
Covered Gravity or Pressure Storage Tanks
Uncovered Storage Tanks or Reservoirs.
(f) The New Carlisle Fire Division shall maintain a current record of all double check valve assembly devices which area part of the fire sprinkler system.
