2509.03 - Pressure reducing standpipe valves.
Pressure restricting type PRVs installed in Class 1 or 3 firefighting standpipe systems where the static pressure is less than 175 psi are undesirable, therefore:
2509.03.1 Flow restricting PRV. All flow restricting type PRVs found in existing Class 1 and Class 3 fire suppression standpipe systems for fire department use shall be replaced with standard valves, or the pressure restricting feature of the PRV shall be permanently disabled. Flow restricting type PRVs in existing buildings shall be replaced or modified to disable the flow restricting feature.
2509.03.2 Pressure regulating PRV. For Class 2 hose stations intended for occupant use where a pressure restricting type PRV is specified by the Ohio Basic Building Code, a pressure regulating type PRV shall be used in its place.
2509.03.3 Flow test. All pressure regulating type PRVs found in existing fire suppression standpipe systems, and all new installations shall be flowed in place, as installed, to verify that the installation is correct, that the device is operating properly, and that the inlet and outlet pressures at the device are in accordance with the design. This testing shall be repeated every 5 years. Initial testing of systems in existing buildings shall be completed by January 1, 1994. Bench testing of the devices is acceptable for subsequent tests, however, the initial testing of any device shall be in place as installed.
2509.03.4 Certification. All testing shall be conducted by and certified by licensed fire protection systems contractors. Static and residual inlet pressure and static and residual outlet pressure and flow shall be recorded on the contractor's test certificate.
2509.03.5 Documentation. The contractor's test certificates documenting all testing shall be provided to the Fire Prevention Bureau and a copy will be kept by the building owner or his agent and shall be kept on the premises available to fire inspection personnel at their request.
2509.03.6 Field adjustable. Where hose valve pressure regulating devices are installed on 2 1/2 inch outlets, they shall be field adjustable, capable of being adjusted through the full adjustment range by a 3/8 inch rod with a maximum required torque of 30 foot-pounds while flowing water. Field adjustment shall not require any hose valve disassembly.
2509.03.7 Approvals. Pressure-regulating devices shall be easily removed by the firefighter. The fire code official must approve PRDs prior to installation.
