boiler problem

Maybe it is an open system, "raised pressure then dropped off" Is there still water at the bleeder of suspect radiator? How many stories above boiler? Do you have a small round tank at boiler, appx 12-16" diameter either right by boiler side or at ceiling above boiler appx 12" diameter by 3-4ft long? Any water leaks at boiler or out of safety relief? All pertinent questions. Tim

    boiler problem

    i had radiator which was not bleeding or heating to the top.i looked at the pressure and it was 9. i called a technician and he showed me how to put water into the system. he raised the pressure and the radiator bled and heating well. but now the pressure has gone down to 9 again. last year i had a new "backup flow valve"?put in. sorry, (i'm not sure of the correct name).so that is not the problem.
    i called a helpline and they said i needed a plumber to drain the water tank. can you give me any ideas? thanks,
