- Very unlikely. The collapsing bubble effect, although much more destructive
- to pipes than water hammer, sounds pretty innocuous, sort of like sand is
- running in the water stream.
-
- The clanking of hot water and steam pipes I believe to be due to the thermal
- expansion of the pipes. This explains why the effect is most prominent when
- the furnace comes on after a spell.
