I live in a semi detached house, and for a couple of years now I have been hearing a knocking noise through the adjoining wall.
I can usually hear it twice a day for about an hour each time.
This would make me think it is related to their central heating system.
It comprises of 3 loud knocks, then silence for 10 seconds, then 3 loud knocks, then silence for 10 seconds, and so on. This continues until whatever is causing it switches off.
It is especially noticeable through the upstairs adjoining wall.
I have mentioned it to the neighbour, who said that it can't be his pump as that is fitted over the other side of the house.
Could this noise be a pump noise transmitted through their pipework and into a radiator on the other side of the wall?
This has only been noticeable over the last couple of years but is now gradually getting louder.
Could it be that their pump is faulty?
If so, how long before it breaks down altogether?
Any ideas as to what this could be would be extremely welcome.
