What does it mean when you hear knocking in your walls?
Tapping in walls could be attributed to the presence of pests such as mice, rats, termites, and wasps, to mention a few. Expansion and contraction of pipes could cause tapping or clicking sounds that may be heard through the walls. Heating ducts may also emit tapping sounds as the heating system turns on.
What does it mean when a knock comes from the wall?
Sounds like a “water hammer” issue in your plumbing. Probably you need to replenish all the plumbing system “air chambers” with air. Your plumber should be able to fix that without open any wall holes. Here is a quick fix you could try:
What makes a knocking noise when you turn on the water?

Where does the knocking sound come from in a condo?
The condo is a newer unit (2004) on a first floor. My tenant has been complaining of an occasional knocking sound coming from the upper half of an interior wall. We have run all the water in the unit and in the unit above it continuously, flushed toilets, etc. and have not found a correlation as to when the knocking comes.
What should I do if my water main is knocking?
Open the lowest faucet (it’s usually outside or in the basement) and let all the water drain out. At this point the air will be “refilled” in the air chambers Turn the lowest faucet off (the one you opened in step #3) and turn the water main back on Let the top faucet run until it stops sputtering, then turn it off
Why are my water pipes knocking against the wall?
Loose supply pipes knocking against a wall. What it is: Over time, the pipes that supply your fixtures with hot and cold water can work themselves loose from their straps (often from water hammer. See below.) Then the high water pressure that passes through the pipes causes them to knock against the wall that they’re supposed to be secured to.
