(a) Backflow prevention assemblies required by this chapter shall be installed at a location and in a manner approved by the Superintendent of Water, or his or her authorized representative and shall be installed by and at the expense of the water consumer. In addition, any backflow prevention assembly required by § 1046.28(a), (b), (c), (d), (e), (f), and (g) shall be installed at a location and in a manner approved by the Superintendent of Water, or his or her authorized representative as required by R.C. § 6111.15 and #3745-95 of the Ohio Administrative Code.
(b) Backflow prevention assemblies installed on the service line to a consumer's water system shall be located on the consumer's side of the water meter, as close to the meter as is reasonably practical, and prior to any other connection.
(c) Pits or vaults will generally not be approved for the installation of any backflow prevention assembly. However, retrofit of an existing fire suppression system with double check detector check backflow prevention assembly may be allowed in a pit or vault if the pit or vault already exists and the pit or vault meets all the following requirements:
(1) Pits or vaults shall be of water-tight construction, be so located and constructed as to prevent flooding and shall be maintained free from standing water by means of either a sump pump or a suitable drain. Such sump pump or drain shall not connect to a sanitary sewer nor permit flooding of the pit or vault by reverse flow from its point of discharge. An access ladder and adequate natural or artificial lighting shall be provided to permit maintenance inspection and testing of the backflow prevention assembly.
(2) If a pit or vault is approved, it shall be understood that when a major system renovation is undertaken these double check detector check backflow prevention assemblies will be moved out of the pit or vault to a suitable location approved by the Superintendent of Water, or his or her authorized representative.
