 Thump noises
Author: Blackmask (CA)

I live in a condo on the first floor. I can hear thumping sounds in the wall. It is so bad that nails are popping out of drywall. I can feel the vibration it is like the earthquake. The interesting part is I can hear the thumping/pipe clinking sounds when upstairs neighbor is not at home. Does that mean my pipes are also connect to downstairs neighbors? I don't know what to do anymore. Plumbers have no clues beside telling me to open the walls.

Yes, your pipes are interconnected with your neighbors' pipes both upstairs and down.

This issue 'may' be caused by a 'worn out' angle stop ANYWHERE in the building.

I have seen this EXACT problem caused by a toilet angle stop 'somewhere' in the system.

Since you are in a condo and the maintenance dept. (if any) can not fix the issue and the problem may be caused locally (your unit) or an other (unknown) unit OR may be a 'common' element issue you may consider MOVING.

a cut or a loose washer can cause a problem like your.
most likely a toilet fill valve "ghost flushing".

A bad toilet fill valve can cause noises even when no one is home.
