I wonder can anyone give me some advice over what has become a very annoying situation?
Approximately three months ago, what I assume to be water hammer started in the airing cupboard of my second floor flat. This manifested, and continues to do so, as a repeated, i.e. every 60 seconds or so, banging or knocking as if the pipes are moving or coughing,
The sound seems to occur primarily during the late evenings and at the night, usually between 01 00 - 04 30 hrs, although I have heard it during the day as well. The sound is also rather loud at approximately 50 decibels.
A plumber was unable to identify the specific cause of the problem but did determine that the stopcock was defective. However, this does not affect the water supply to, and within, my flat.
So, can anyone advise:

So, can anyone advise:
- Can a defective stopcock cause repeated water hammer?
- Why such water hammer frequently happens at the times described above?
- What can / should be done about this?
