text: I'm staying in a three story home with radiators and old plumbing (probably copper). I'm a guest and it's a rental with a management company (they fix a few things here and there but not most things).
  The noise happens intermittently all night every night. Likely also intermittently all day but I'm not usually in the bedroom at night. It's quite loud. I can hear it in the ceiling (or maybe walls) and it seems to come from different areas in tandem (like a call and response). Best description would be a clicking sound.
  I was thinking of trying to bleed the radiators but seems like it could also be the supply plumbing instead, so I'm not sure where to start or what to do. I don't know much about plumbing noises. There's at least 11 radiators in the house.
  Suggestions? Get ear plugs?
