Backflow Prevention Devices Sample Clauses

The Backflow Prevention Devices clause requires the installation and maintenance of equipment designed to prevent the reverse flow of water or other substances into the potable water supply. In practice, this means that property owners or tenants must ensure that appropriate backflow prevention devices are fitted to plumbing systems, particularly where there is a risk of contamination, such as irrigation systems or industrial connections. The core function of this clause is to protect public health and safety by preventing contamination of clean water sources, thereby complying with regulatory standards and reducing liability for waterborne hazards.

An air gap separation, to be approved, shall be at least twice the diameter of the supply pipe, measured vertically above the top rim of the vessel, but in no case less than one inch. 2. A double check valve assembly or a reduced pressure principle backflow prevention device shall be approved by the Superintendent of Water, and shall appear on the current list of approved backflow prevention devices of the Ohio Environmental Protection Agency. 3. In interchangeable connection, to be approved, shall be either a swing type connector or a four-way valve of the lubricated plug type that operates through a mechanism which unseats the plug, turns it ninety degrees and reseats the plug. Four-way valves shall not be used as stop valves but must have separate stop valves on each pipe connected to the valve. The telltale port on the four-way valve shall have no piping connected and the threads or flange on this port shall be destroyed so that a connection cannot be made. B. Existing backflow prevention devices approved by the Superintendent of Water or the Director of the Ohio Environmental Protection Agency at the time of installation and properly maintained shall, except for inspection, testing and maintenance requirements, be excluded from the requirement of Section 8.A of this regulation providing the Superintendent of Water is assured that they will satisfactorily protect the public potable water system. Whenever the existing device is moved from the present location or requires more than minimum maintenance or when the Superintendent of Water finds that the maintenance of the device constitutes a hazard to health, the device shall be replaced by a backflow prevention device meeting the requirements of these regulations.
