water hammer with large radiator
We have a one pipe steam system. We have this large radiator on the second floor, 15 sections. We are experiencing very loud water hammer as it starts to heat up. It also doesn't get warm all the way across.
Unfortunately, the return line runs across the middle of the house under the floor boards so we can't see if that line is tilted properly. I haven't tried to raise the radiator yet, however, it is tilted properly back to the return.
We can't really tell if the water hammer is coming from the radiator itself or the return lines somewhere. It's so loud we actually just shutoff the intake to this radiator last winter.
It also has a shiny new adjustable vent the same as we've used on all the other radiators.
I could try a smaller radiator that I have kicking around. I don't think we really need this large radiator where it is since it's an open space and we've got two other smaller radiators in 2 rooms connected to this one. We could eventually move it. Thoughts on next steps? Try raising the radiator first? Try the smaller radiator?
