Pipes clanging/banging - need help- 4 questions
We have a one-pipe steam steam system with one boiler servicing 12 units (10 with steam, 2 basement units with hot water return). There is a radiator on the first floor that sounds like someone is inside the metal with a hammer and at time it is frightening and sounds like it is going to break. The sound resonates to the basement units and always happens when the heat goes on. We asked that the boiler be skimmed regularly. They drained water out the other night since it appears to over-fill (someone installed an auto feeder to a boiler that cannot use one so we have to hit the reset button continually when it shuts off). It still makes these cranking, wrenching sounds at all times of day and in the middle of the night. My questions are:
1) Will regular skimming of boiler fix this alone? If so, how often? We have a Weil-McLain Series 5 Gas-Fired Boiler.
2) The radiator valve and/or vent is not opening and closing properly on the banging radiator. The radiator is very old. One plumber lifted it out of the floor to install a new valve that didn't close initially. Now the plumber says it is a vent that is not working and to replace it requires more work (not sure what as he no longer services the building). Does this make any sense?
3) The thermostat is manual and not locked (not my idea) and when people get cold, they bump it up one notch - sometimes two. The noise follows. Should the thermostat be in the hands of any condo owner to change at will?
4) We had a pipe in the basement break recently and spread black sludge all over the residents' floor. It was hot and and dirty and very scary. Fortunately, no one was hurt by this. However, the sludge build up from the boiler to this basement unit could happen again. Does not skimming the boiler regularly cause more sludge and jeapordize the integrity of the heating pipes?
Any recommendations would be appreciated.
