Clicking from built-in steam riser

DebiMemmolo

I just finished a remodel in a 100 year old building with a 1-pipe system. We replaced the old radiators with Charleston Pro by Steam Radiators. We have one rise, in a wall, that clicks during the cycle. When I place my hand on the wall, I can actually feel a vibration. If I move my hand along the wall, the intensity changes. I assume there's something rubbing against something in the wall. I work from home and it's driving me mad. Mad enough that I am about to cut into the wall in an attempt to stop it.

I know water hammer can be hard to locate, but this is a different sound. And, I can feel the vibration. Should I open the wall?

Thanks for the help!

That's almost certainly an expansion noise -- particularly if it is early in a heating cycle. Look around and see if you can figure out what the riser is rubbing against and either move it enough to clear or put a rubbing piece in -- I use pieces from plastic milk bottles.

Thanks Jaimie. My issue is that it's in a wall. Sounds like a hole is in order. That's probably cheaper than a stint at the psych ward.

Start in the cellar if you can that binding could be where it passes through the floor.
Is the pipe original to the system? Or was it replace, moved or anchored during the wood phase?
Check where it passes through the floor to the radiator as well. Good luck
