    I have an oil fired boiler with forced hot water
    Cast iron radiators with a dual pipe system & diverter valves on main pipe
    Each radiator has an ON/OFF valve on the radiator
    Many do not work & are open all the time
    Heat works just fine

    I'm having two radiators moved, & the on/off valves doe not work
    We never turn them off or on
    Shining a flashlight down the pipe/valve I can't even see any way that it closes to stop water

    Should I have the valves replaced ?
